Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0020] In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more than two. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" may mean: A exists alone, A and B exist at the same time, and B exists alone.

[0021] The descriptions of "first", "second", etc. involved in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the technical features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] Reference Figure 1 , shows a flow chart of an embodiment of a method for managing the carbon footprint of a lithium battery provided by the present invention, the method comprising: S101, obtaining the first carbon footprint data of each link in the whole life cycle of the lithium battery; the first carbon footprint data of each link includes: the energy used in each link, the energy metering equipment, the materials input and output in each link, the material metering equipment, the process equipment used in each link, the basic information of the process equipment, the waste generated in each link, the waste metering equipment, the first carbon emission factor of each link, the testing equipment, testing environment and testing method of the first carbon emission factor, the first carbon emission amount of each link, and at least one of the calculation methods of the first carbon emission amount.

[0024] The various links in the entire life cycle of lithium batteries include lithium battery raw material acquisition, lithium battery manufacturing, lithium battery delivery, lithium battery use, lithium battery recycling and other links.

[0025] The energy used in each link can be electricity, water power, steam, fuel, etc. The materials input into each link can be raw materials, auxiliary materials, finished products or semi-finished products, etc. The materials output from each link can be raw materials, auxiliary materials, finished products or semi-finished products, etc. that have use value. The waste generated in each link can be waste gas, waste water and solid waste generated in each link.

[0026] In the process of obtaining raw materials for lithium batteries, manufacturing lithium batteries and recycling lithium batteries, there are usually multiple processes. The process equipment used in these links and the basic information of the process equipment can also be uploaded as the first carbon footprint data. The basic information of the process equipment may include: the model, source, performance and other information of the process equipment.

[0027] Carbon Emission Factor refers to the greenhouse gas emissions generated by a unit activity or unit product, usually expressed in carbon dioxide equivalent (CO2e). Carbon emission factor is an important parameter for calculating and evaluating carbon footprint. The first carbon emission factor can be a carbon emission factor for an entire link.

[0028] Carbon emissions refer to the carbon dioxide (CO2) produced directly or indirectly by an activity, process or system over a specific period of time (such as a year). 2 ) or other greenhouse gases (such as methane, nitrous oxide, etc.), usually expressed in carbon dioxide equivalent (CO2e). Carbon emissions can be calculated based on the test results of non-dispersive infrared (NDIR) analyzers, ultraviolet differential optical absorption spectrometers (UV-DOAS) systems, Fourier transform infrared (FTIR) analyzers, electrochemical sensors, and photoacoustic spectroscopy (PAS) analyzers. The first carbon emissions can be the carbon emissions for an entire link.

[0029] S102, after collecting statistics on the first carbon footprint data of the lithium battery, a carbon footprint report of the lithium battery is generated.

[0030] After obtaining the first carbon footprint data of the lithium battery, the first carbon footprint data can be integrated and counted to obtain a carbon footprint report. The carbon footprint report can be in a table form, a graphic form, a text form, etc. This embodiment does not specifically limit the form of the carbon footprint report.

[0031] S103, uploading the first carbon footprint data and the carbon footprint report to the blockchain for storage.

[0032] The first carbon footprint data and the carbon footprint report can both be stored in the blockchain.

[0033] The relevant technology usually processes the information such as carbon emission factors, carbon emissions and carbon footprints through commitment, and then stores the information such as carbon emission factors, carbon emissions and carbon footprints and the commitment information in the blockchain to ensure the credibility of the information such as carbon emission factors, carbon emissions and carbon footprints. However, different links involve different companies, and each company measures and counts its own carbon footprint and other information according to its own methods. Therefore, the accuracy of the data obtained by measurement and statistics is not recognized by each other, let alone by the international community. Even if each company commits to the authenticity of the carbon footprint and other information it has measured and counted, the credibility of the commitment may not be high.

[0034] In view of the above problems, the first carbon footprint data uploaded to the blockchain by the present invention includes the energy used in each link of the whole life cycle of the lithium battery, the energy metering equipment, the materials input and output in each link, the material metering equipment, the waste generated in each link, and the waste metering equipment. The national / international requirements for metering equipment can be queried. By comparing the national / international requirements and the metering equipment in the first carbon footprint data stored in the blockchain, the credibility of the metering equipment can be known. The credibility of the energy, material and waste metering results is guaranteed by the credibility of the metering equipment. In addition, the credibility of the carbon footprint assessment parameters (first carbon emission factor or first carbon emission) calculated based on the metering results is guaranteed.

[0035] The first carbon footprint data of the present invention also includes: the process equipment used in each link and the basic information of the process equipment, and the process equipment information is used to ensure that the process meets the national / international quality requirements for the process, thereby ensuring the credibility of the process. The specific process method may involve confidentiality issues and cannot be disclosed to assist in proving the credibility of the process. Therefore, the present invention assists in proving the credibility of the process by disclosing the basic information of the process equipment, and then assists in proving the credibility of the calculation results of the carbon footprint assessment parameters through the credibility of the process.

[0036] Furthermore, the first carbon footprint data of the present invention also includes: the first carbon emission factor of each link, the test equipment, test environment and test method of the first carbon emission factor, the first carbon emission amount of each link, and the calculation method of the first carbon emission amount. By providing the detailed test / calculation process of the first carbon emission factor and the first carbon emission amount, which are important evaluation / calculation parameters of the carbon footprint, the credibility of the first carbon emission factor and the first carbon emission amount is further guaranteed. Then, by ensuring the credibility of the important evaluation parameters of the carbon footprint, the credibility of the carbon footprint finally calculated can be guaranteed.

[0037] Finally, the first carbon footprint data is integrated to generate a carbon footprint report, and both the first carbon footprint data and the carbon footprint report are uploaded to the blockchain to ensure that the first carbon footprint data and the carbon footprint report are not tampered with.

[0038] In one embodiment, the target link in each link includes multiple processes; wherein the target link includes at least one of a lithium battery raw material acquisition link, a lithium battery manufacturing link, and a lithium battery recycling link; then S102 specifically includes: obtaining a preset carbon footprint model, and determining a sub-target carbon footprint model from the carbon footprint model; the sub-target carbon footprint model is at least one of a carbon footprint model matching each link, a carbon footprint model matching each first process, and a carbon footprint model matching each second process; the first carbon footprint data is correspondingly imported into each sub-target carbon footprint model to obtain a target carbon footprint model; after statistics are collected on the second carbon footprint data in each of the target carbon footprint models, a carbon footprint report of the lithium battery is generated.

[0039] Reference Figure 2 , showing a carbon footprint modeling flow chart provided by the present invention. The various links in the full life cycle of lithium batteries may include: lithium battery raw material acquisition link, lithium battery manufacturing link, lithium battery delivery link, lithium battery use link and lithium battery recycling link. Single configurable modules can be combined to form a lithium battery product model, and a single lithium battery product model can be associated with multiple similar products; product models and modules can be copied and used, and modules can be flexibly adjusted to facilitate R&D personnel to complete carbon footprint calculations. When modeling a certain lithium battery product, modeling can be performed for each link to generate a carbon footprint model. The carbon footprint model is used to display the input and output of materials in any link, the use and generation of energy such as electricity, steam, and diesel, and the generation of three wastes.

[0040] And, among these links, the lithium battery raw material acquisition link, lithium battery manufacturing link and lithium battery recycling link usually also include multiple processes. For example, the lithium battery manufacturing link includes the positive electrode manufacturing process of the lithium battery and the negative electrode manufacturing process of the lithium battery, and the negative electrode manufacturing process of the lithium battery further includes stirring, coating, rolling and strip cutting processes. When modeling a certain lithium battery product, you can also further model each process to generate a carbon footprint model. The carbon footprint model is used to show the input and output of materials in any process, the use and generation of energy such as electricity, steam and diesel, and the generation of three wastes.

[0041] After various carbon footprint models are preset in advance, when they are needed, the sub-target carbon footprint model can be directly selected from the preset carbon footprint model, and the first carbon footprint data can be correspondingly imported into each sub-target carbon footprint model to obtain the target carbon footprint model. Figure 2As shown, the sub-target carbon footprint model includes a carbon footprint model for strip cutting. The raw materials\semi-finished products, electricity\water\auxiliary materials used in the strip cutting process recorded in the first carbon footprint data, the three wastes, and semi-finished products\finished products information generated by the process are imported into the sub-target carbon footprint model to obtain the target carbon footprint model.

[0042] In each target carbon footprint model, the second carbon footprint data of a certain link or process can be clearly recorded.

[0043] Reference Figure 3 , shows a data collection flow chart of a lithium battery manufacturing process provided by the present invention. The data of materials, energy, materials and wastes used in each process in the lithium battery manufacturing process can be recorded and collected one by one.

[0044] In one embodiment, the first carbon footprint data also includes the second carbon emission factor of each process, the test equipment, test environment and test method of the second carbon emission factor, and at least one of the second carbon emission amount and the calculation method of the second carbon emission amount of each process. This embodiment also records the second carbon emission factor and / or the second carbon emission amount of each process.

[0045] In one embodiment, the carbon footprint management method further includes: generating a plurality of carbon footprint data to be certified corresponding to each target carbon footprint model according to each target carbon footprint model; sending the plurality of carbon footprint data to be certified to a third-party carbon footprint certification agency, and obtaining a certification from the third-party carbon footprint certification agency; and uploading the certification to the blockchain for storage.

[0046] Because each target carbon footprint model clearly records the second carbon footprint data of a certain link or process. Therefore, the carbon footprint data to be certified can be directly generated based on the second carbon footprint data in the target carbon footprint model, and then the carbon footprint data to be certified can be sent to a third-party carbon footprint certification agency for certification. Figure 4 , showing a carbon footprint online certification flow chart provided by the present invention. First, the user can configure the accounting boundary through the carbon footprint management system. The accounting boundary configuration includes: information of the enterprise to be accounted for, accounting monitoring plan, accounting industry, etc. And based on the configuration of the accounting boundary, a verification agreement is signed with a third-party carbon footprint certification agency. Then, data reporting is performed through the carbon footprint management system. Data reporting includes: generating data to be reported based on the target carbon footprint model and other relevant data, and sending the data to be reported to a third-party carbon footprint certification agency for certification. Finally, the verification report and certification generated by the third-party carbon footprint certification agency are received through the carbon footprint management system.

[0047] The embodiment of the present invention can more conveniently generate the carbon footprint data to be certified for each link or each process based on the target carbon footprint model, send the carbon footprint data to be certified to a third-party carbon footprint certification agency for certification, receive the verification report and certification from the third-party carbon footprint certification agency, and upload the verification report and certification to the blockchain for storage, and prove the credibility of the first carbon footprint data or carbon footprint assessment parameters through the verification report and certification from the third-party carbon footprint certification agency.

[0048] In one embodiment, S102 may specifically include: obtaining the customer's carbon footprint requirements; generating a first carbon footprint report after statistics of the second carbon footprint data in each target carbon footprint model according to the customer's carbon footprint requirements; the first carbon footprint report includes: the carbon emissions of each link, the carbon emissions of each first process, the carbon emissions of each second process, the completion of the carbon footprint requirements and at least one of the recommended carbon reduction paths.

[0049] The embodiments of the present invention can meet the needs of the client, so that the client can better understand the relevant information of the carbon footprint.

[0050] In one embodiment, the carbon footprint report includes a second carbon footprint report that complies with national carbon footprint disclosure standards and a third carbon footprint report that complies with international carbon footprint disclosure standards. National and international disclosure requirements for carbon footprint related information may not be exactly the same, so the national carbon footprint disclosure standards and the international carbon footprint disclosure standards can be obtained, and then the second carbon footprint report that complies with national carbon footprint disclosure standards and the third carbon footprint report that complies with international carbon footprint disclosure standards can be generated based on the first carbon footprint data. The second carbon footprint report and the third carbon footprint report can be used as needed. For example, when lithium battery products are exported internationally, the third carbon footprint report can be used.

[0051] Reference Figure 5 , showing a schematic diagram of a battery passport provided by the present invention. The battery passport is equivalent to the third carbon footprint report. The battery passport can simply display the general information of the battery, the battery management system information, the sustainable development information and the QR code, etc. More detailed information of the battery can be obtained by scanning the QR code.
