[Background technology]

[0002] Battery supply has to meet several regulatory requirements, which vary depending on the chemical used in the battery. For example, in the automotive supply chain, chemical manufacturers provide standardized information using the International Chemical Product Data System (IMDS). Such a system allows data to be collected along the automotive supply chain. Participants in the automotive supply chain register with the IMDS service and keep their product entries in a central database provided and hosted by a third-party provider.

[0003] Systems like IMDS are static with respect to data, error-prone and cumbersome to handle and maintain. Due to the very specific and centralized setup of such systems, data exchange and sharing is laborious. To achieve a more efficient and reliable battery production, data exchange and sharing between value chain players needs to be simplified.

[0058] The following embodiments are merely examples for implementing the methods, systems, or computer elements disclosed herein and should not be considered limiting.

[0059] FIG. 1 shows a schematic diagram of a battery 10 having battery identification elements 12, 14.

[0060] The battery 10 may include a battery management system 16 and a number of battery cells 18 disposed within a battery housing 20. The battery cells 18 may be arranged within a battery pack or module having a number of the battery cells 18. The battery cells 10 may include an electrolyte 22, a negative electrode element 24, a positive electrode element 26, and a separator 28.

[0061] Depending on the application, the battery includes different material compositions for different components. For example, the battery may be a lithium-ion battery. The positive electrode element 26 may include an active material coated on a current collector foil, such as an aluminum foil or a copper foil. In addition, it may include a binder, polyvinylidene fluoride (PVDF) and carbon as a conductive agent. The positive electrode active material may include layered oxides (LiMO2 with M=Co, Ni, Al, such as LCO(LiCoO2), NCM(LiNixMnyCozO2), NCA(LiNixCoyAlzO2), etc.), spinels (LiMO2O4 with M=Mn, Ni, such as LMO(LiMnO4), etc.), or phosphates (LiMPO4 with M=Fe, Mn, Co, Ni, such as LiFePO4).

[0062] The negative electrode element 24 may include a negative electrode active material coated on a current collector foil, such as an aluminum foil or a copper foil. The negative electrode active material may include synthetic graphite, natural graphite, or a composition thereof. Additionally, the active material may include silicon, SiO2, lithium titanate (LTO), or a combination thereof. Additionally, the active material may include a binder, such as styrene-butadiene rubber (SBR), a polymeric thickener, such as carboxymethyl cellulose (CMC), and a carbonate as a conductive agent.

[0063] The electrolyte may include salts, solvents, and additives such as carbonates, esters, and ethers to provide electrical conductivity. A mixture of cyclic carbonates, such as ethylene carbonate (EC) and propylene carbonate (PC), and open-chain carbonates, such as dimethyl carbonate (DMC), may be included. Lithium hexafluorophosphate (LiPF6), lithium bis(trifluoromethyl)sulfonylimide (LiTFSI) and its derivatives (e.g., lithium bis(fluorosulfonyl)imide (LiFSI)), or lithium [tris(pentafluoroethyl)-trifluorophosphate] (LiFAP), lithium 4,5-dicyano-2-trifluoromethylimidazolide (LiTDI), lithium bis(oxalyl)borate (LiBOB), ethyl methyl carbonate (EMC), and / or diethyl carbonate (DEC) may be used as the conductive salt.

[0064] The separator divides the space between the electrodes and allows ions to pass through. Types of separators include microporous membranes, ceramic-coated separators, nonwoven mats, solid inorganic electrolytes, and polymer electrolytes. Polyolefin-based membranes (e.g., coated with PVDF or ceramic) may be used.

[0065] The battery identification elements 12, 14 may be physically associated with the battery 10. The identification elements 12, 14 may be physically attached to the battery housing and may be part of the battery management system 16. The identification elements 12, 14 may be located inside or outside the battery housing 20. The identification elements 12, 14 may be passive identification elements 14. The passive elements 14 may be located on the outer surface of the battery housing 20. The passive elements 14 may be based on markers embedded in the material. The passive elements 14 may include printed codes such as bar codes or QR codes. The identification elements 12, 14 may be active identification elements 14. The active elements 14 may be transmitter or transceiver tags such as RFID tags, enabling communication via, for example, NFC, Bluetooth, Zigbee, or other suitable short to medium range communication protocols. The identification elements 14 may be part of the battery management system 16, or a digital battery identifier may be stored in the battery management system 16.

[0066] The battery identification elements 12, 14 may be associated with a digital battery identifier. The digital battery identifier may be unique to the battery. The digital battery identifier may be further associated with data related to the identified battery. Such data may include any data collected during the production or life of the battery 10. For example, such data may include material data, such as material composition data collected during the production of the battery, or monitoring data collected during the use of the battery may be associated with the digital battery identifier.

[0067] The digital battery identifier may include at least one decentralized identifier. The decentralized identifier may include a unique identifier uniquely associated with the data owner and the identified battery 10. The decentralized identifier may include a Universally Unique IDentifier (UUID) or a Digital IDentifier (DID). The decentralized identifier may be issued by a central ID issuer or a decentralized ID issuer. The decentralized identifier may include authentication information for authentication of data associated with the identified battery. Through the unique association of the decentralized identifier with the battery 10, the identified access to data associated with the identified battery is controlled by at least one data owner. This is in contrast to a central authority scheme where the identifier is provided by a central authority and access to the data is controlled by such central authority. Decentralized in this context refers to the use of the identifier as controlled by any data owner. The data may be hosted in an associated database or under the control of the data owner. The identification elements 12, 14 may be configured to provide a digital battery identifier for accessing data associated with the identified battery.

[0068] In particular, the digital battery identifier may be associated with material composition data that defines the material composition of one or more components of the battery. The digital battery identifier may be associated with the battery 10, and the material composition data may define the material composition of one or more components of the battery 10.

[0069] FIG. 2 shows a schematic of a battery component 30 having identification elements 32, 34.

[0070] The battery component 30 may include one or more subcomponents of the battery 10. The subcomponents may include the battery management system 16, the battery housing 20, a battery module or pack having a plurality of battery cells 22, the battery cells 22, or a combination of such subcomponents. A battery component identification element 32, 34 may be associated with the battery component 30. The identification element 32, 34 may be physically attached to the battery component 30. The identification element 32, 34 may be located inside or outside the battery component 30. The identification element 32, 34 may be a passive or active identification element 32, 34 as described in the context of FIG. 1. The battery identification element 32, 34 may be associated with a digital battery component identifier. The digital battery identifier may include at least one distributed identifier associated with the identified battery component 30 as described in the context of FIG. 1. In particular, the identification element 32, 34 may be configured to provide a digital battery component identifier for accessing data related to the identified battery component, such as material composition data. The battery identifier may be associated with a component 30 whose material composition data defines a material composition.

[0071] 3a-3c show different computing environments, such as centralized, decentralized and distributed. The disclosed method, apparatus, system, use and computer elements may be implemented in a distributed or at least partially distributed computing environment. Data provision, determination and processing may be realized by different computing nodes, which may be implemented in a centralized, distributed or discrete computing environment.

[0072] Figures 3a, b show example embodiments of a centralized computing environment and a distributed computing environment having computing nodes. Figure 3c shows an exemplary embodiment of a distributed computing environment. Figure 3d shows an example environment for making data accessible. Such an environment may be implemented according to standards based on the International Data Space (IDS) and Digital Identifier from the W3C. Such an implementation helps to make data associated with a distributed identifier from a material provider accessible to a data consumer.

[0073] FIG. 3a illustrates an example embodiment of a centralized computing system 100 having a central computing node 101 (shown as a solid circle in the center) and multiple peripheral computing nodes 101.1-101.n (shown as solid circles around the edges). The term "computing system" is broadly defined herein to include one or more computing nodes, a system of nodes, or a combination thereof. The term "computing node" is broadly defined herein to refer to any device or system that includes at least one physical and tangible processor, and / or physical and tangible memory that may have computer executable instructions thereon that are executed by the processor. Computing nodes now take an increasingly diverse range of forms. Computing nodes may be, for example, handheld devices, production equipment, sensors, monitoring systems, control systems, home appliances, laptop computers, desktop computers, mainframes, data centers, or devices not traditionally considered to be computing nodes, such as wearables (e.g., glasses, watches, etc.). Memory may be in any form, depending on the nature and form of the computing node.

[0074] In this example, the peripheral computing nodes 101.1-101.n may be connected to one central computing system (or server). In another example, the peripheral computing nodes 101.1-101.n may be connected to the central computing node, for example, via a terminal server (not shown). Most of the functionality is performed by or obtained from the central computing node (also referred to as a remote centralized location). One peripheral computing node 101.n is expanded to provide an overview of the components present in the peripheral computing nodes. The central computing node 101 may have the same components described in relation to the peripheral computing nodes 101.n.

[0075] Each computing node 101, 101.1-101.n may include at least one hardware processor 102 and memory 104. The term "processor" may refer to any logic circuitry configured to perform the basic operations of a computer or system, and / or may generally refer to a device configured to perform calculations or logical operations. In particular, a processor or computer processor may be configured to process the basic instructions that run a computer or system. It may be a semiconductor-based processor, a quantum processor, or any other type of processor configuration that processes instructions. As an example, a processor may be or may include a central processing unit (CPU). A processor may be a graphics processing unit ("GPU"), a tensor processing unit ("TPU"), a Complex Instruction Set Computing ("CISC") microprocessor, a Reduced Instruction Set Computing ("RISC") microprocessor, a Very Long Instruction Word ("VLIW") microprocessor, or a processor implementing other instruction sets, or a combination of instruction sets. The processing means may be one or more dedicated processing devices, such as an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), a Complex Programmable Logic Device (CPLD), a Digital Signal Processor (DSP), a network processor, etc. The methods, systems, and devices described herein may be implemented as software in a DSP, a microcontroller, or any other side processor, or may be implemented as hardware circuitry within an ASIC, CPLD, FPGA. The term "processor" may refer to one or more processing devices, such as a distributed system of processing devices located across multiple computer systems (e.g., cloud computing, etc.), and is not limited to a single device unless otherwise specified.

[0076] Memory 104 may refer to physical system memory, which may be volatile, non-volatile, or a combination thereof. Memory may include non-volatile mass storage devices such as physical storage media. Memory may be a computer readable storage medium, such as RAM, ROM, EEPROM, CD-ROM, or other non-magnetic disk storage devices such as optical disk storage devices, magnetic disk storage devices, solid state disks, or any physical and tangible storage medium that can be used to store desired program code means in the form of computer executable instructions or data structures and that can be accessed by a computer system. Furthermore, memory may be a computer readable medium (also called a transmission medium) that stores computer executable instructions. Furthermore, upon reaching various computing system components, program code means in the form of computer executable instructions or data structures are automatically transferred from the transmission medium to the storage medium (or vice versa). For example, computer executable instructions or data structures received over a network or data link may be buffered in a RAM in a network interface module (e.g., a "NIC") and then eventually transferred to the computing system RAM and / or to a less volatile storage medium of the computing system. As such, it should be understood that storage media may be included in computing components that also (or even primarily) utilize transmission media.

[0077] A computing node 101, 101.1-101.n may include a number of structures 106 referred to as "executable components, executable instructions, computer executable instructions or instructions." For example, memory 104 of a computing node 101, 101.1-101.n may be depicted as including executable components 106. The term "executable components" or any synonyms thereof may refer to structures well understood by those skilled in the computing arts as structures that may be, or may be executed by, software, hardware, or a combination thereof. For example, when implemented in software, those skilled in the art will understand that the executable components structures include software objects, routines, methods, etc. that execute on a computing node 101, 101.1-101.n, whether such executable components reside in a heap of a computing node 101, 101.1-101.n, or whether the executable components reside on a computer readable storage medium. In such cases, one skilled in the art will recognize that the structure of the executable components resides on a computer-readable medium such that, when interpreted by one or more processors (e.g., by processor threads) of the computing nodes 101, 101.1-101.n, it causes the computing nodes 101, 101.1-101.n to perform a function. Such structures may be directly readable by a processor (as would be the case if the executable components were binary). Alternatively, the structures may be structured to be interpretable and / or compiled (either in a single step or multiple steps) to generate a binary that is directly interpretable by a processor. Such an understanding of example structures of executable components, when using the term "executable components," is well within the understanding of one of ordinary skill in the computing arts.Examples of executable components implemented in hardware include hard-coded or hard-wired logic gates that are implemented exclusively or nearly exclusively in hardware (e.g., in a field programmable gate array (FPGA), application specific integrated circuit (ASIC), or any other specialized circuitry). In this specification, the terms "component," "agent," "manager," "service," "engine," "module," "virtual machine," and the like are used interchangeably with the term "executable component."

[0078] The processor 102 of each computing node 101, 101.1-101.n may direct the operation of each computing node 101, 101.1-101.n in response to executing computer-executable instructions constituting executable components. For example, such computer-executable instructions may be embodied on one or more computer-readable media forming a computer program product. The computer-executable instructions may be stored in the memory 104 of each computing node 101, 101.1-101.n. The computer-executable instructions include, for example, instructions and data that, when executed by the processor 101, cause the general-purpose computing node 101, 101.1-101.n, the special-purpose computing node 101, 101.1-101.n, or the special-purpose processing device to perform a certain function or group of functions. Alternatively or additionally, the computer-executable instructions may configure the computing node 101, 101.1-101.n to perform a certain function or group of functions. The computer-executable instructions may be binaries (or even instructions) that undergo some translation (eg, compilation) before direct execution by a processor, such as intermediate format instructions such as assembly language (or even source code).

[0079] Each computing node 101, 101.1-101.n may include a communication channel 108 that allows each computing node 101.1-101.n to communicate with the central computing node 101. A "network" may be defined as one or more data links that allow the transmission of electronic data between computing nodes 101, 101.1-101.n and / or between modules and / or other electronic devices. When information is transferred or provided to a computing node 101, 101.1-101.n over a network or other communications connection (either wired, wireless, or a combination of wired and wireless), the computing node 101, 101.1-101.n properly considers the connection to be a transmission medium. A transmission medium may include networks and / or data links that may be used to transmit desired program code means in the form of computer-executable instructions or data structures and that may be accessed by general-purpose or special-purpose computing nodes 101, 101.1-101.n. Combinations of the above may also be included within the scope of computer-readable media.

[0080] Computing nodes 101, 101.1-101.n may further include a user interface system 110 for use in interfacing with a user. User interface system 110 may include output mechanism 110A as well as input mechanism 110B. The principles described herein are not limited to the exact output mechanism 110A or input mechanism 110B as this will depend on the nature of the device. However, output mechanism 110A may include, for example, a display, a speaker, a display, a haptic output, a hologram, etc. Examples of input mechanism 110B may include, for example, a microphone, a touch screen, a hologram, a camera, a keyboard, a mouse or other pointer input, any type of sensor, etc.

[0081] FIG. 3b illustrates an example embodiment of a distributed computing environment 100' having multiple computing nodes 101.1'-101.n', depicted by filled circles. In contrast to the centralized computing environment 100 illustrated in FIG. 3a, the computing nodes 101.1'-101.n' of the distributed computing environment are not connected to, and therefore are not under the control of, the central computing node 101. Instead, both hardware and software resources may be allocated to the individual computing nodes 101.1'-101.n' (local or remote computing systems) and data may be distributed to the various computing nodes 101.1'-101.n' to perform tasks. Thus, in a distributed system environment, program modules may be located in both local and remote memory storage devices. One computing node 101' is expanded to provide an overview of the components present in the computing node 101'. In this example, the computing node 101' has the same components as described in connection with FIG. 3a.

[0082] FIG. 3c illustrates an example embodiment of a discrete computing environment 103. As used herein, "discrete computing" may refer to any computing that utilizes multiple computing resources. Such utilization may be achieved through virtualization of physical computing resources. An example of discrete computing is cloud computing. "Cloud computing" may refer to a model that enables on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services). When discrete, a cloud computing environment may be distributed internally within an organization and / or across multiple organizations. In this example, the discrete cloud computing environment 103 may include the following computing resources: mobile devices 114, applications 116, databases 118, data storage 120, and servers 122. The cloud computing environment 103 may be deployed as a public cloud 124, a private cloud 126, or a hybrid cloud 128. The private cloud 124 is owned by an organization, and only members of that organization with appropriate access may utilize the private cloud 126, and data within the private cloud may be at least confidential. In contrast, data stored in a public cloud 126 may be open to anyone on the Internet. A hybrid cloud 128 may be a combination of both a private cloud 124 and a public cloud 126, allowing some data to be kept private while other data is made public.

[0083] 1 and 2, the battery or battery component identifiers provided by the identification elements 12, 14, 32, 34 may be processed at least in part in a distributed computing environment. The battery or battery component identifiers may be configured to access battery or battery component data, such as material data or material composition data.

[0084] Figure 3d shows an example environment for making data accessible according to standards set by the International Data Spaces Association (IDSA; e.g., IDS Reference Architecture Version 3.0 April 2019) or the W3C (Decentralized Identifiers (DIDs) v1.0, Core architecture, data model, and representations according to W3C Proposed Recommendation 03 August 2021). Such an implementation helps make data associated with decentralized identifiers from material providers accessible to data consumers.

[0085] The at least partially decentralized structure based on the distributed identifiers enables novel methods, apparatus, systems, computer elements, computer executable instructions, and their use in the battery recycling process described below.

[0086] FIG. 4 illustrates an example of ID-based data for at least one battery component, ID-based battery passport data, and an ID manager.

[0087] The ID may be a decentralized ID (DID). The ID-based battery passport may be a DID document associated with the DID. The ID-based owner data may be associated with at least one battery component, such as a battery material, a battery cell, a battery cell pack, or a battery. The ID-based battery component data may include an ID associated with at least one battery component, such as a battery material, a battery cell, a battery cell pack, or a battery, and may include an authentication mechanism. The ID-based battery component data may include battery data electronically associated with a physical entity of the at least one battery component. In this context, electronically associated may refer to data stored in a repository or wallet of the producer. Such data may be securely stored and / or managed on a system associated with the production facility, such as an organizational server or a client device. The ID-based battery component data may include a DID, a private key, and a public key. The ID-based battery component data may be owned and managed by at least one producer of at least one battery component. At least one producer of at least one battery component may own and manage an ID associated with at least one battery component as a DID entity, and a private key and public key pair associated with the DID. The DID may be understood as an identifier, and authentication information may be associated or uniquely linked to such identifier.

[0088] The DID entity may be at least one component of a battery, including a raw material, an intermediate product, a component, a component assembly, or a final product. The DID entity may be a raw material, an electrode active material, a battery cell, a battery cell pack, a battery, or any combination thereof. The DID owner may be a supply chain participant or a manufacturer, such as a chemical manufacturer, that produces a chemical. The DID owner may be an upstream participant in the supply chain of a chemical manufacturer, such as a supplier that supplies a raw material chemical or a precursor to a chemical. The DID owner may be a downstream participant in the supply chain of a chemical manufacturer, such as a customer that consumes a chemical to produce an intermediate product, a component, a component assembly, or a final product. The DID owner may be any participant in the supply chain, including a chemical supplier, an intermediate chemical manufacturer, an intermediate component manufacturer, a component manufacturer, a component assembly manufacturer, an electrode active material manufacturer, a battery cell manufacturer, a battery cell pack manufacturer, a battery manufacturer, or a final product manufacturer.

[0089] The DID may be any identifier associated with the DID entity and / or the DID owner. Preferably, the identifier is unique to the DID entity and / or the DID owner. The identifier may be unique at least within the scope in which the DID is expected to be used. The identifier may be a locally or globally unique identifier for any participant in the supply chain, including at least one component of the battery, including raw materials, intermediate products, components, component assemblies, or final products or their aggregates, a chemical manufacturer producing a chemical, an upstream participant in the chemical manufacturer's supply chain, a downstream participant in the chemical manufacturer's supply chain or their aggregates, a raw material chemical supplier, an intermediate chemical manufacturer, an intermediate part manufacturer, a component manufacturer, a component assembly manufacturer, or a final product manufacturer or their aggregates.

[0090] A DID may be a Uniform Resource Identifier (URI), such as a Uniform Resource Locator (URL). A DID may be an Internationalized Resource Identifier (IRI). A DID may be a random string of numbers and letters to enhance security. In one embodiment, a DID may be a string of 128 letters and numbers, such as a method-specific did, for example, scheme did:method name:did:example:ebfeb1f712ebc6f1c276e12ec21. DIDs may be decentralized, independent of centralized third-party management systems, and under the control of the DID owner.

[0091] The battery passport as a DID document 16 may be associated with a DID. Thus, the battery passport 16 may include a reference to a DID associated with the DID entity described by the DID document. The DID document 16 may include authentication information, such as a public key. The public key may be used by a third party entity authorized by the DID owner / subject 14 to access information and data owned by the DID owner / subject 14. The public key may also be used to verify that the DID owner 14 actually owns or controls the DID. The DID document 16 may include authentication information, authorization information, for example, to authorize a third party entity to read the DID document or parts of the DID document 16, without giving the third party the right to prove ownership of the DID.

[0092] The battery passport may include one or more representations that digitally link to product data or chemical product data, for example, by a service endpoint. The service endpoint may include a network address at which a service operates on behalf of the DID owner. In particular, the service endpoint may point to a service of the DID owner that provides access to the battery data. Such services may include services that read or analyze the battery data. The battery data may include chemical product declaration data, chemical product safety data, certificate of analysis data, emissions data, product carbon impact trace data, product environmental impact trace data, chemical product specification data, product information, technical application data, production data, material composition data, recycled content data, or combinations thereof.

[0093] The battery passport 16 may include various other information, such as metadata that specifies when the battery passport 16 was created, when it was last modified, and / or when it expired, or when at least one component of the battery was manufactured or shipped.

[0094] The DID and the battery passport may be associated with a data registry node, such as a centralized data service system or a distributed data service system, such as the distributed ledger or blockchain 10. Possible blockchain systems include Quorum, Hyperledger Fabric, etc. The discrete ledger or blockchain 10 may be used to store a representation of the DID 14 that points to the battery passport 16. The representation of the DID may be stored in discrete computing nodes of the discrete ledger or blockchain 10. For example, a DID hash may be stored in multiple computing nodes of the discrete ledger 10 and may point to the location of the battery passport 16. In some embodiments, the battery passport 16 may be stored in the discrete ledger. Alternatively, in other embodiments, the battery passport 16 may be stored in a data storage (not shown) associated with the discrete ledger or blockchain 10.

[0095] The discrete ledger or blockchain 10 may be any distributed, discrete network that includes various computing nodes that communicate with each other. For example, the discrete ledger 10 may include a first discrete computing node 12.1, a second discrete computing node 12.2, a third discrete computing node 12.3, and any number of additional discrete computing nodes, as shown at 12.4, 12.5. The discrete ledger or blockchain 10 may operate according to any known standard or method for discrete ledgers. Examples of conventional discrete ledgers that correspond to the discrete ledger or blockchain 10 include, but are not limited to, Bitcoin [BTC], Ethereum, Litecoin, etc.

[0096] FIG. 5 illustrates another example of ID-based data for at least one battery component, ID-based battery passport data, and an ID manager.

[0097] The example of FIG. 5 is essentially similar to the example of FIG. 4. The example of FIG. 5 is certificate-based using a central ID manager. The ID-based certificate data may include authentication data of the certificate owner and the certificate issuer. For example, a cryptographic signature from the issuer may bind the data owner's public key to the ID. The identifier may be a locally or globally unique identifier of at least one component of the battery, including at least one component of the battery (including raw materials, intermediate products, components, component assemblies, or end products, or a collection thereof); a chemical manufacturer producing the chemical, an upstream participant in the chemical manufacturer's supply chain, a downstream participant in the chemical manufacturer's supply chain, or a combination thereof; a raw material chemical supplier, an intermediate chemical manufacturer, a component manufacturer, a component assembly manufacturer, or an end product manufacturer, or a combination thereof. The identity subject may be at least one component of the battery, including raw materials, intermediate products, components, component assemblies, or end products. The identity subject may be raw materials, electrode active materials, battery cells, battery cell packs, batteries, or any combination thereof. The identity subject may be a supply chain participant or manufacturer, such as a chemical manufacturer producing the chemical. An ID Owner can be an upstream participant in a chemical producer's supply chain, such as a supplier that provides raw chemicals or precursors to produce a chemical.

An ID Owner can be any participant in the supply chain, including raw chemical suppliers, intermediate chemicals, intermediate part manufacturers, component manufacturers, component assembly manufacturers, and electrode active materials.

[0098] The ID may be a unique ID (e.g., a UID) as described in connection with the DID of FIG. 2. The certificate may be an X.509 certificate, such as X509v3.

The certificates may be associated with an identity manager, such as a certificate issuing service and / or a dynamic provisioning service that provides dynamic attribute tokens (e.g., OAuth access tokens). The information required to validate the certificates is provided via an authentication registry associated with the certificate issuing service and / or the dynamic provisioning service. For example, in the April 2019 IDSA Reference Architecture Model, Version 3.0, a data owner, a certificate authority (CA), a connector associated with a dynamic attribute provisioning service (DAPS), and a connector associated with a data consumer service are used to validate the identity prior to the execution of the data exchange (not shown). For this purpose, such connectors include one or more certificates, such as an X.509 certificate. In this manner, the connector possesses a unique identifier embedded in an X.509 certificate that identifies the connector instance.

[0100] FIG. 6 illustrates an example of a manufacturing facility that produces at least one component of a battery associated with a battery passport.

[0101] The manufacturing facility shown in FIG. 6 can manufacture at least one component of a battery. The manufacturing facility can manufacture an electrode active material, such as an anode active material or a cathode active material. The manufacturing facility can include one or more production plants. For example, a production facility for manufacturing an electrode active material, such as a cathode active material, can include at least one precursor electrode active material production plant, such as at least one precursor cathode active material (PCAM) plant for processing a transition metal into a precursor, such as a transition metal carbonate, oxide, or hydroxide, and at least one cathode active material (CAM) plant for processing a precursor, such as a transition metal carbonate, oxide, or hydroxide, into a cathode active material. In other embodiments, the production facility can manufacture a battery cell, a battery pack, a battery, or an end product including a battery.

[0102] The physical inputs to the production facility may include materials such as raw materials, intermediate materials, or components that may be assembled. The raw materials may be virgin or recycled raw materials. In the case of the cathode active material, the raw materials such as metals such as cobalt, lithium, copper, or nickel may be virgin or recycled materials. The physical inputs to the production facility may include individual battery components such as battery cells, battery packs, batteries, etc. that may be assembled.

[0103] The physical input may be associated with a distributed identifier, as described in the context of Figures 4, 5, 11, 12, 13. The physical input may be registered with the production facility. The registration may include providing a distributed identifier associated with the physical input. The providing of the distributed identifier may include reading a physical identifier element physically connected to the physical input, as described in the context of Figures 1 or 2. The providing of the distributed identifier may include accessing a database containing the distributed identifiers and obtaining the distributed identifier associated with the physical input.

[0104] Based on the provided distributed identifier, battery data associated with such distributed identifier may be accessed. Access may be granted through authentication and authorization based on authentication and authorization information associated with the distributed identifier. Based on the distributed identifier, battery data such as chemical product declaration data, chemical product safety data, analytical data certificate, emission data, product carbon impact data, product environmental impact data, chemical product specification data, product information, technical application data, production data, performance data, quality data, material composition data, recycled content data, or combinations thereof may be accessed. The battery data may be accessed via a data service associated with each distributed identifier and requesting access to the battery data controlled by a physical input data owner. The data owner may be a producer of the physical input. The data service may include computer executable instructions that operate at least in part in the distributed computing environment. Such computer executable instructions may be based on authentication information, authorization information, and / or a Json Web Token (JWT) that includes a digital representation that points to the battery data or a portion thereof. The digital representation may include an endpoint for data exchange or sharing (resource endpoint) or an endpoint for service interaction (service endpoint) that is uniquely identified via a communication protocol. A digital representation of the battery data or a portion thereof may be uniquely associated with the distributed identifier. The battery data may be used in a manufacturing process in a production facility.

[0105] The production facility may produce a physical output based on one or more physical inputs. The physical output of the production facility may be associated with a physical identifier. The physical output of the production facility may be physically connected to a physical identifier element as described in the context of Figures 1 and 2. The physical identifier may be assigned to identifier information associated with the distributed identifier. For such assignment, the physical identifier element may be read or a database including the physical identifier may be accessed. A request to provide a distributed identifier may be initiated to assign the physical identifier to the distributed identifier. In this manner, the distributed identifier may be assigned to the physical output. Providing the distributed identifier may include accessing a database including the distributed identifier and associated information, such as authentication information. Providing the distributed identifier may include accessing a distributed service to provide the distributed identifier and associated information, such as authentication information. In response to the request, a battery passport may be generated that includes the distributed identifier and data related to battery data of at least one component of the battery. The data related to the battery data may include a representation, such as a pointer or link, to the battery data. The distributed identifier may be associated with data related to the battery data of the physical output. The decentralized identifier may further be associated, assigned, or linked to the decentralized identifier of the physical input. The battery passport may be provided to the decentralized network for access by other participants or producers of the network. In this way, the chain of materials from input to output can be tracked and made available for further manufacturing steps without exposing the battery data in an uncontrolled way.

[0106] The above process steps may be executed via an operating system of the production facility. In this embodiment, the operating system may include a collector configured to collect battery data and / or physical identifiers as described above. The collector may be configured to collect battery data associated with components of the battery or associated with the production of components of the battery, the components of the battery being connected to or including physical identifiers. The operating system may include an ID reader, among others, configured to provide a physical ID of the physical input or output as described above. The system may further include an assigner configured to assign a decentralized identifier and associated information to the physical output as described above. The operating system may further include an ID provider configured to provide a decentralized identifier and associated information as described above.

[0107] FIG. 7 illustrates another example of a production facility that produces at least one component of a battery associated with a battery passport.

[0108] The process steps described in the context of FIG. 6 may be executed via an operating system of the production facility through interaction with an assigner, collector, or reader, or ID provider. In this embodiment, the operating system may be communicatively connected to the production facility and the assigner, collector, ID reader, or ID provider. The operating system may be configured to provide battery data from the production facility. The operating system may include a collector configured to provide battery data from the production facility. The operating system may include an ID reader configured to read a physical identifier element physically connected to a physical input or output. The assigner may be configured to assign a distributed identifier and associated information to a physical identifier of the physical output, as described above in the context of FIG. 6. The ID provider may be configured to provide a distributed identifier and associated information, as described above in the context of FIG. 6. The ID reader may be configured to provide a physical identifier of the physical input or output, as described above in the context of FIG. 6. The assigner, collector, ID reader, and / or ID provider may be configured as distributed services or applications running over a distributed network.

[0109] Figures 6 and 7 show only two embodiments and any combination of the system components shown in Figures 6 and 7 may be possible. For example, the ID reader may be configured as part of the operating system, while the ID provider and assigner may not be configured as part of the operating system.

[0110] Figures 8 to 10 show examples of tracking materials in the production of a battery, from raw materials, through the electrode active material and battery, to the final product. Figure 8 shows an example of tracking materials specifically in the production of the electrode active material.

[0111] In the manufacture of electrode active materials, raw materials may be provided as physical inputs. The raw materials may include transition metals such as cobalt, nickel, manganese, etc. The raw materials may include virgin or recycled materials. The raw materials may be associated with a distributed identifier. The distributed identifier may be associated with a digital twin of the raw materials. The distributed identifier may be associated with raw material data such as a tag of the virgin or recycled material, material properties related to environmental impact, or material properties related to origin.

[0112] The production of electrode active materials may include a two-step process: 1) production of precursor materials, 2) production of electrode active materials. To produce precursor materials, raw materials may be used as physical inputs. The precursor production operating system may access data related to the raw materials based on a distributed identifier, such as from a raw material provider. Such data may be used to operate the production. For example, if the raw materials are recycled materials, a production step of purifying the recycled material may be included. For example, if the raw materials are virgin materials, the purification step may be omitted. The precursor materials may be formed by co-precipitating raw materials, such as transition metals, as carbonates, oxides, or preferably basic or non-basic hydroxides. The production data from the precursor production may be stored and / or associated with the distributed identifier.

[0113] In a second step, precursor material is provided and an electrode active material can be produced. The precursor material can include precursors produced by a precursor production. The precursor material can include recycled precursor material or precursor material produced by a different entity. Such precursor material is associated with a distributed identifier via which data related to the precursor material can be accessible.

[0114] The precursor may be mixed with a lithium source, such as LiOH, LhO, U2CO3, and calcined (fired) at high temperatures. The lithium salt may be used as a hydrate or in a dehydrated form. Calcination (also called baking), commonly referred to as thermal or heat treatment of the precursor, may be carried out at temperatures ranging from 600 to 1000°C. The heat treatment may be carried out in a heating zone of an oven or kiln. During the heat treatment, a solid-state reaction takes place to form the electrode active material. The electrode active material may be packaged, for example, in powder form.

[0115] The produced and packaged electrode active material may be assigned a distributed identifier and associated information, as shown in Figures 4, 5, 11, 12, and 13. The packaged electrode active material may include a physical identifier element, such as, for example, a QR code, physically attached to the package. Such a physical identifier element may be assigned to a distributed identifier. The assignment of the physical identifier element and the distributed identifier may be performed via an ID generator / assigner running locally on the distributed system and / or on the discrete system.

[0116] For example, the packaging line may include a detector that detects a physical identifier on each package. Based on such recognition, the electrode active material production operating system may request provision of a distributed identifier, which may be assigned to the physical identifier. In response to the request, a battery passport may be generated that includes the distributed identifier and data related to the electrode active material. For such generation, data related to the electrode active material that was recorded before and / or during production of the electrode active material may be collected or accessed. Such data may be provided by the electrode material production operating system or a storage environment connected to the electrode material production operating system. This may include data collected and stored during precursor material production.

[0117] The data related to the electrode active material may include identifiers of raw materials used in the production of the electrode active material. The data related to the electrode active material may include data related to raw materials accessible via the raw material's distributed identifier. The data related to the electrode active material may include data related to the material composition of the electrode active material. The material composition data may be related to the chemical composition of the electrode active material. The material composition data may define at least one component of the chemical composition of the electrode active material, such as a transition metal-containing component. The material composition data may be associated with a positive electrode active material. In such an embodiment, the material composition may define the chemical composition of the positive electrode active material. Examples include lithium nickel manganese (NCM type), such as lithium nickel cobalt manganese oxide (LiNiCoMnO2), lithium iron phosphate (LPF type), such as lithium iron phosphate (LiFePO4 / C), lithium nickel manganese spinel (LiNi 0.5 Mn 1.5 O4) Lithium nickel manganese (LMNO type), lithium nickel cobalt aluminum (NCA type) such as lithium nickel cobalt aluminum oxide (LiNiCoAlO2), lithium manganese (LMO type) such as lithium manganese oxide (LiMn2O4), lithium cobalt (LCO type) such as lithium cobalt oxide (LiCoO2), or a combination thereof.

[0118] The data related to the electrode active material may include data related to characteristics related to environmental impacts, such as CO2 impact footprint and recycled content. For example, the data related to the electrode active material may define the recycled content of cobalt, lead, nickel, and lithium. Such recycled content may be directly associated with the distribution identifier of the electrode active material, or indirectly associated with the distribution identifier of the electrode active material, for example, via the distribution identifier of raw material or precursor material. The data related to the electrode active material may include data related to production conditions provided by the operating system of the electrode active material production. The data related to the electrode active material may include data related to the operating conditions provided by the operating system of the electrode active material production.

[0119] Figure 9 shows an example of material tracking in the production of a battery cell.

[0120] For the production of a battery cell, different materials may be provided as physical inputs from material providers. The electrode active material may be associated with a distributed identifier and associated information as shown in Figures 4, 5, 11, 12, 13. The distributed identifier may be associated with data related to the electrode active material or the digital twin of the electrode active material. The distributed identifier may be associated with the electrode active material data as described in the context of Figure 8.

[0121] Electrode manufacturing may include multiple steps based on the input materials. The input materials may be materials such as graphite, conductive carbon black, solvent, binder, and one or more additives for the positive electrode. The input materials may be materials such as LMNO, carbon black, solvent, and one or more binders for the negative electrode. The electrode production operating system may initiate the production process based on the operating parameters of the different process steps. The production process may include equipment for dry mixing the active material, additives such as carbon black and binder, equipment for wet dispersion, adding solvent, dispersing and homogenizing into a slurry, equipment for coating the slurry on one or both sides of foils (copper for the negative electrode and aluminum for the positive electrode), equipment for drying, equipment for calendaring and / or slitting to produce the electrode material, for example in the form of a roller electrode material.

[0122] The electrode production operating system can access data relating to the electrode active materials or raw materials, for example based on distributed identifiers from suppliers of the electrode active materials or raw materials. Such data can be used to manipulate production.

[0123] Produced and packaged electrodes may be assigned a distributed identifier. Packaged electrodes may include an identifier element, such as a QR code, physically attached to the package. Such a physical identifier element may be assigned a distributed identifier. The assignment of physical identifiers and distributed identifiers may be performed through an ID generator running locally on the distributed and / or discrete systems.

[0124] For example, the packaging line may include a detector that detects the physical identifier of each package. Based on such recognition, the electrode production operating system may request to provide a distributed identifier assigned to the physical identifier. In response to the request, a battery passport may be generated that includes the distributed identifier and data related to the electrode active material. For such generation, data related to the electrode that was recorded before and / or during the production of the electrode may be collected or accessed. Such data may be provided by the electrode material production operating system or a storage environment that is connected to the electrode production operating system.

[0125] The data relating to the electrode may include a distribution identifier for the electrode active material or for raw materials used to produce the electrode active material. The data relating to the electrode may include data relating to the electrode active material or raw materials, for example accessible via a distribution identifier for the electrode active material or raw materials.

[0126] To produce a battery or battery cell, electrodes and other components may be provided as physical inputs. A component, such as an electrode active material, may be associated with a distributed identifier. The distributed identifier may be associated with a digital twin of the component, such as the electrode active material. The distributed identifier may be associated with a component, such as electrode active material data, as described in the context of FIG. 8.

[0127] Battery or cell assembly and finishing may include multiple steps based on physical inputs. The input materials may be electrodes, separators, electrolyte, and packaging materials for the negative electrode. The cell production operating system may initiate the production process based on the operating parameters of the different process steps. The production process may include equipment for electrode separation and stacking, equipment for electrode and separator packaging, equipment for electrolyte filling, equipment for degassing, and equipment for quality control and testing. Data collected during production may be stored.

[0128] The battery or cell production operating system can access data related to the physical inputs, for example based on distributed identifiers from electrode active material or raw material suppliers. Such data can be used to steer production.

[0129] Produced and packaged cells may be assigned a decentralized identifier and associated information as shown in Figures 4, 5, 11, 12, and 13. The packaged cells or batteries may include an identifier element, such as a QR code, physically attached to the package. Such a physical identifier element may be assigned a decentralized identifier. The assignment of the physical identifier and the decentralized identifier may be performed via an ID generator running locally on the distributed and / or discrete systems.

[0130] For example, the packaging line may include a detector that detects the physical identifier on each package. Based on such recognition, the cell production operating system may request to provide a distributed identifier assigned to the physical identifier. In response to this request, a battery passport may be generated that includes the distributed identifier and data related to the cell or battery. For such generation, data related to the cell that was recorded before and / or during the production of the cell or battery may be collected or accessed. Such data may be provided by a storage environment connected to the cell or battery production operating system or the electrode production operating system.

[0132] FIG. 10 shows an example of material tracking in the production of an end product such as a car or power tool with the battery produced as shown in FIG.

[0133] Various components may be provided as inputs to the production of the final product. The battery may be associated with a distributed identifier. The distributed identifier may be associated with a digital twin of the battery and associated information. The distributed identifier may be associated with cell data as described in the context of FIG. 8 or 9.

[0134] The manufacturing may include multiple steps based on individual input materials, which may be any individual components.

[0135] The production operating system can access data relating to the battery, electrode active material, or raw materials based on, for example, a distributed identifier from a supplier of the electrode active material or raw materials. Such data can be used to operate production.

[0136] The final product may be assigned a decentralized identifier. The final product may include an identifier element, such as a physically attached QR code. Such a physical identifier element may be assigned a decentralized identifier. The assignment of the physical identifier and the decentralized identifier may be performed through an ID generator running locally on the decentralized and / or discrete systems.

[0137] 9 to 10 are merely illustrative examples. Different embodiments are possible for ID generation and association of the digital twin or battery to any component or end product.

[0138] 11 to 13 show examples of battery passports of different embodiments for connecting decentralized identities and related information along the battery value chain.

[0139] FIG. 11 illustrates one example of tracking materials in the production of a car based on a single distributed identifier associated with each production output or component of a battery. The distributed identifiers may be associated with raw materials, intermediate materials such as electrode active materials, battery cells, batteries, and cars with batteries. The IDs may be provided by the producer of the first or last physical entity. Data related to such physical entities may be associated with such a single ID and made accessible to other supply chain participants via a distributed network. The connection of the physical entities may be provided via the single ID and the associated data. The IDs and the associated data may be hashed individually and / or hashed in connection. For example, each data set provided in a JWT file may be hashed and the combination of hashes may also be hashed. Such hashes may be provided in the distributed network. In this way, any supply chain participant with access to such data can check for corruption of the data by hashing the received data associated with the ID and matching the hashes.

[0140] FIG. 12 shows another example of tracking materials in the production of a car based on multiple distributed identifiers associated with a car identifier. A set of IDs may be generated at each production step along the value chain, and the IDs may be linked in a hierarchical order that orders the embedding. The connection of physical entities may be provided through a hierarchy of IDs and associated data. The IDs and associated data may be hashed individually or in conjunction. For example, each data set provided in a JWT file may be hashed, and the combination of hashes may be hashed. Such hashes may be provided in a distributed network. In this way, any supply chain participant with access to such data may check for corruption of the data by hashing the received data associated with the ID and matching the hashes.

[0141] FIG. 13 shows another example of tracking materials in the production of a car based on multiple distributed identifiers associated with a car identifier. A set of IDs may be generated at each production step along the value chain, and the IDs may be linked but completely separate. Data related to the physical entities may be associated with a separate ID for each physical entity and made accessible to other supply chain participants through the distributed network. The connection of the physical entities may be provided through the separate IDs and the associated data. The separate IDs and the associated data may be hashed individually or in conjunction. The hashed connection may provide the connection of the physical entities in the supply chain. For example, each data set provided in the JWT file may be hashed and the combination of hashes may be hashed. Such hashes may be provided in the distributed network. In this way, supply chain participants accessing such data may check for corruption of the data by hashing the received data associated with the IDs and matching the hashes. Furthermore, the connected hashes may provide a way to track the physical entities through the supply chain.

[0142] The embodiments illustrated in Figures 11-13 are merely examples, and multiple combinations of direct and indirect ID connections via hashing, linking, or other mechanisms are possible.

[0143] FIG. 14 illustrates one example of using one or more battery passports in the context of a supply chain having at least two producers.

[0144] In the example of Figure 14, the producer may be a cathode active material producer. This is merely an example, and the embodiments described herein may be equally valid for any other material producer in the battery supply chain.

[0145] Cathode active material producers can store environmental impact data, such as carbon footprint data. Cathode active material producers can store recycling data from production, such as recycled content of cobalt, nickel, lithium, lead, etc. Cathode active material producers can store data related to manufacturing, such as production date, production location, batch number, producer ID, etc. Cathode active material producers can store data related to material makeup or chemical composition.

[0146] A cathode active material producer may provide access to data related to electrode active materials that the cathode active material producer has provided to a battery producer. Such data sharing may be performed via a distributed network, where distributed data providers may provide data and data consumers may consume data directly or indirectly.

[0147] To access data related to the electrode active material, the battery producer service component may use a public portion of encryption information, such as the public keys of the electrode active material producer and the battery producer. Based on the encryption information and the authentication protocol, the access by the battery producer service component may be authenticated. In a further step, the battery producer service component may request access to data related to the electrode active material or a subset of such data. The data or the subset may be linked to authorization rules. Based on such authorization rules, the access by the battery producer service component may be allowed or denied. If access is allowed, the data may be transferred or processed from the battery producer service component as provided by the electrode active material producer service component.

[0148] In this way, a secure and controlled data sharing can be achieved. In particular, battery data can be shared with selected participants of the network while the data remains under the control of the data owner. Battery data, including material composition, can be made available to producer participants along the value chain. This allows for attribute tracking and aggregation and appropriate processing in production, testing or quality control.

[0149] 15 through 17 show examples of providing access to data via one or more battery passports.

[0150] Through the distributed setup described above, different supply chain participants or producers to the end consumer can access data from the supply chain participants or producers. Such access to data may include forwarding the data to the requester, processing the data, and forwarding the processing results to the requester. The example in FIG. 15 shows the data that may be accessed based on the distributed identifier of the car or battery. Material data may be provided from different material providers that supplied materials for the production of the battery or car. Environmental impact data may be provided in aggregate from different material suppliers that were involved in the production of the battery or car. Lifetime data may be provided as collected during the use of the end product.

[0151] The example of FIG. 16 shows material data such as electrode active material data provided by an electrode active material producer, electrolyte data provided by an electrolyte producer, and housing data provided by a housing producer.

[0152] The example in Figure 17 shows environmental data such as total emissions data aggregated from data provided by producers of car and battery components, production emissions data provided by producers of car and battery components, and recycled content data provided by producers of car and battery components.
