Description

[0001] This application claims priority. The application number of the prior application is PCT / CN2023 / 134168, the filing date of the prior application is November 24, 2023, and the entire content of the prior application is incorporated herein by reference. Technical Field

[0002] This application relates to the technical field of new energy materials, and particularly to a method, device, equipment, and storage medium for calculating and tracing the proportion of recycled materials based on RMS. Background Art

[0003] With the rapid development of the global new energy economy and the rise of the electric vehicle industry, the demand for batteries has increased significantly. Batteries and their cathode materials contain many metal elements, such as cobalt, lithium, nickel, etc. However, if all raw materials are used as virgin minerals when producing batteries and their cathode materials, there will be a risk of resource depletion and challenges to environmental sustainability. To address these issues, many countries and regions have successively formulated regulations, requiring a certain proportion of waste or recycled materials to be used in the production of batteries and their cathode materials, and have proposed a phased implementation schedule. These policies aim to reduce the exploitation of virgin minerals and promote the efficient recycling and circular utilization of waste resources.

[0004] Due to the complex production process of batteries and their cathode materials and the involvement of multiple raw material sources, there is currently a lack of a method that can scientifically and systematically calculate the proportion of recycled materials in batteries, cathode materials, and production raw materials. At the same time, the technical research on tracing recycled materials throughout the supply chain is also imperfect, which brings many difficulties to regulatory authorities and industry practices. Furthermore, the proportion of recycled materials in batteries, cathode materials, and production raw materials is currently unknown. Therefore, how to establish a method that can relatively scientifically and systematically calculate the proportion of recycled materials in batteries, cathode materials, and production raw materials and trace the recycled materials has become an urgent problem to be solved in the current technical field.

[0129] Step S11: During a preset acquisition period, collect production material data within the preset system boundary range on the production line; wherein, the production material data includes: the proportion of purchased salt in the i element of all salts used in the production of self-produced cathode material raw materials, the proportion of recycled materials in the i element of the purchased salt, the proportion of self-produced salt in the i element of all salts used in the production of self-produced cathode material raw materials, and the proportion of recycled materials in the i element of the self-produced salt; all salts used in the production of self-produced cathode material raw materials are composed of self-produced salt and purchased salt. Among them, the self-produced cathode material raw material is a compound containing the i element; the i element is any one of nickel, cobalt, manganese, aluminum, iron, phosphorus or lithium.

[0130] Step S12: According to the production material data and the preset calculation formula for the proportion of recycled materials in the i element of the self-produced cathode material raw material, obtain the proportion of recycled materials in the i element of the self-produced cathode material raw material.

[0131] It should be noted that according to the scale of different factories, enterprises will configure production lines of different lengths. The production line can be all or part of the production lines for producing products such as batteries, cathode materials, precursors, lithium salts, self-produced salts or black powder. According to the calculation requirements for the proportion of recycled materials of different products, collect the production material data on the corresponding production line.

[0132] In some embodiments of the present application, in the production line from black powder to salt solution, generally, during the process of generating salt solution from black powder, a certain amount of purchased materials are added for batching as needed. That is, black powder and purchased materials are used during the process of generating salt solution. Black powder generally refers to the black powdery substance obtained after crushing recycled materials, that is, the proportion of recycled materials in black powder is 100%.

[0133] In some embodiments of the present application, in the production line from salt to the raw material of the positive electrode material, generally, according to needs, a certain amount of purchased salt is added to the self-produced salt for batching to generate the self-produced raw material of the positive electrode material. That is, self-produced salt and purchased salt are used when generating the self-produced raw material of the positive electrode material. Among them, self-produced salt refers to the salt produced by oneself, and purchased salt refers to the salt purchased from external suppliers. Self-produced salt and purchased salt are the same substance, which can be nickel sulfate, cobalt sulfate, manganese sulfate, lithium sulfate, aluminum nitrate, ammonium dihydrogen phosphate, ferrous sulfate or other similar substances. The self-produced raw material of the positive electrode material refers to the raw material of the positive electrode material produced by oneself, and the purchased raw material of the positive electrode material refers to the raw material of the positive electrode material purchased from external suppliers. The self-produced raw material of the positive electrode material and the purchased raw material of the positive electrode material are the same substance, which can be the precursor or lithium salt for producing the positive electrode material. The precursor can be nickel cobalt manganese hydroxide, nickel cobalt aluminum hydroxide, iron phosphate, manganese carbonate, cobalt tetroxide or other similar substances, and the lithium salt can be lithium carbonate, lithium hydroxide or other similar substances.

[0134] In some embodiments of the present application, in the production line from the raw material of the positive electrode material to the positive electrode material, generally, according to needs, a certain amount of purchased raw material of the positive electrode material is added to the self-produced raw material of the positive electrode material for batching to generate the self-produced positive electrode material. That is, the self-produced raw material of the positive electrode material and the purchased raw material of the positive electrode material are used when generating the self-produced positive electrode material. The self-produced positive electrode material refers to the positive electrode material produced by oneself, and the purchased positive electrode material refers to the positive electrode material purchased from external suppliers. The self-produced positive electrode material and the purchased positive electrode material are the same substance, which can be lithium nickel cobalt manganate, lithium nickel cobalt aluminate, lithium iron phosphate, lithium manganate, lithium cobaltate, lithium-rich manganese oxide or other similar substances. In some embodiments of the present application, in the production line from the positive electrode material to the battery, generally, according to needs, a certain amount of purchased positive electrode material is added to the self-produced positive electrode material for batching to generate the battery. That is, the raw materials of the battery are the self-produced positive electrode material and the purchased positive electrode material.

[0135] In some embodiments of the present application, recovering element i from waste batteries to generate cathode materials includes: extracting the i element of the waste batteries into a leaching solution. Then, on the one hand, when extracting a precursor according to the leaching solution, an externally purchased metal salt is added; on the other hand, when extracting a lithium salt according to the leaching solution, externally purchased crude salt is added. The extracted precursor and lithium salt are mixed with an externally purchased precursor and refined salt to obtain a mixed material, and the cathode material is generated according to the mixed material. According to the production processes of the above-mentioned precursor and lithium salt, it can be seen that the production processes of the precursor and lithium salt are similar, and the time nodes of the input raw materials are similar, both of which are generated by adding externally purchased salts after the leaching solution. In order to facilitate the use of a single recycled material accounting formula to be applicable to both the precursor and the lithium salt, a common name is given to the precursor and the lithium salt, such as cathode material raw materials; similarly, a common name is also given to the externally purchased metal salt and the externally purchased crude salt, such as externally purchased salts. At the same time, for the sake of name correspondence, a new name is given to the leaching solution, such as self-produced salt. After applying the new name accounting formula, it can be used to calculate the proportion of recycled materials of each element in the precursor and can also be used to calculate the proportion of recycled materials of each element in the lithium salt, which is both convenient and accurate.

[0136] In some embodiments of the present application, when extracting cathode material raw materials according to the leaching solution, adding externally purchased salts includes: subjecting the leaching solution to extraction, and adding the qualified solution extracted into the batching to make a batching solution, and adding the externally purchased salts to the batching solution for reaction to extract the self-produced cathode material raw materials.

[0137] In some embodiments of the present application, the externally purchased salt is at least one of externally purchased lithium salt, externally purchased nickel salt, externally purchased cobalt salt, externally purchased manganese salt, externally purchased iron salt or externally purchased phosphorus salt.

[0138] In some embodiments of the present application, as Figure 2 shown, it is a process flow chart of the recycled material proportion accounting and traceability method based on RMS provided by the embodiments of the present application. Specifically, first obtain the module of the waste battery, and then disassemble the module to obtain the battery monomers. This process is the process before the leaching process, and coding traceability can be used to trace the recycled materials; discharge, pyrolyze and crush the battery monomers and process materials, and screen out the black powder of the battery; subject the battery black powder to oxidative leaching to extract the leaching solution.

[0139] In Figure 2In [specific process], when extracting the precursor (i.e., the raw material for self-produced cathode materials) from the leaching solution, the qualified solution extracted from the leaching solution is added to the formulation to make a formulated solution; an externally purchased nickel-cobalt salt is added to the formulated solution for reaction to obtain the precursor (i.e., the raw material for self-produced cathode materials). The process of preparing the formulated solution from the leaching solution belongs to the leaching process, and the recycled materials can be traced by time period. Then, the extracted lithium salt and the precursor are mixed, and externally purchased refined salt (i.e., lithium salt, equivalent to the externally purchased raw material for cathode materials) and externally purchased precursor (i.e., the externally purchased raw material for cathode materials) are added to obtain a mixed material. According to the reaction of the mixed material, the NCM ternary recycled cathode material composed of nickel (Ni), cobalt (Co), manganese (Mn), and lithium (Li) is prepared; among them, the process of preparing the mixed material is the process after leaching, and the recycled materials can be traced by batch according to the mixed material.

[0140] In Figure 2 In [specific process], the lithium salt and the precursor (collectively referred to as the raw material for self-produced cathode materials) can be respectively extracted from the leaching solution. When extracting the lithium salt from the leaching solution, the leaching solution is extracted to obtain a raffinate; the raffinate is subjected to a causticization reaction to generate a causticized solution; and externally purchased crude salt (i.e., externally purchased salt) is added to the causticized solution to fully extract the lithium salt in the causticized solution.

[0141] It should be noted that the externally purchased lithium salt includes externally purchased refined salt and externally purchased crude salt. Externally purchased crude salt (i.e., externally purchased salt) is added when extracting the lithium salt, and externally purchased refined salt (i.e., the externally purchased raw material for cathode materials) is added during calcination; in Figure 2 the externally purchased metal salt in [specific process] includes the externally purchased nickel-cobalt salt.

[0142] Finally, the raw material for self-produced cathode materials is obtained according to the lithium salt and the precursor. Then, the raw material for self-produced cathode materials, the externally purchased refined lithium salt, and the externally purchased raw material for cathode materials are mixed to obtain the self-produced cathode materials, realizing the recovery of the self-produced cathode materials from waste batteries and obtaining the recycled cathode materials.

[0143] It should be noted that during the process of separately extracting the lithium salt and the NCM recycled cathode material from the causticized solution and the mixed material, the failed lithium element compound is directly repaired according to the externally purchased lithium salt to restore the electrochemical performance of the compound, and the restored compound can be reused as recycled material; similarly, the externally purchased nickel-cobalt salt is added to the formulated solution, and the externally purchased precursor is added to the mixed material. After preparing the self-produced cathode materials based on the RMS, the proportion of the recycled materials of each element in the waste batteries in the self-produced cathode materials includes both the recycled raw materials in the waste batteries and the recycled raw materials of the externally purchased lithium salt, the externally purchased nickel-cobalt salt, and the externally purchased precursor, so that the proportion of the recycled materials of each element based on the RMS can be accurately calculated.

[0144] In some embodiments of the present application, the RMS process in Figure 2 is used to recycle and regenerate the NCM ternary recycled cathode material, or the Figure 2The process of recycling and regenerating the RMS reclaims and regenerates the NCA ternary recycled cathode material composed of nickel, cobalt, aluminum (Al), and lithium to obtain the proportion of recycled materials in the NCM ternary recycled cathode material or the NCA ternary recycled cathode material.

[0145] In some embodiments of the present application, for the production process of the battery, refer to Figure 3 . As shown in the figure, on the production line from the cathode material to the battery, generally, as needed, a certain amount of externally purchased cathode material is added to the self-produced cathode material for batching to produce the battery. That is, the raw materials of the battery are the self-produced cathode material and the externally purchased cathode material.

[0146] The embodiments of the present application adopt the method of regenerating the cathode material after recovering element i from waste batteries based on RMS and tracing the recycled materials based on RMS. Therefore, it is possible to commonly use the elements in waste batteries to generate the cathode material, which has high applicability and practicability.

[0147] In some embodiments of the present application, when all the raw materials of the self-produced salt are recycled materials, the proportion of recycled materials in the element i of the self-produced salt is 100%. The calculation formula for the proportion of recycled materials in the element i of the raw materials of the self-produced cathode material is:

[0148] R Pi =R Mi *y i +(1 - y i );

[0149] In the formula, y i is the proportion of the externally purchased salt in the element i of all the salts used in the production of the raw materials of the self-produced cathode material, in %. (1 - y i ) is the proportion of the self-produced salt in the element i of all the salts used in the production of the raw materials of the self-produced cathode material, in %. R Mi is the proportion of recycled materials in the element i of the externally purchased salt, in %. R Pi is the proportion of recycled materials in the element i of the raw materials of the self-produced cathode material, in %.

[0150] It should be noted that the proportion of recycled materials in the element i of the externally purchased salt should be provided by the corresponding external supplier, and the external supplier can calculate it using the proportion calculation method of the recycled materials provided in the present application.

[0151] In some embodiments of the present application, the production material data further includes: the mass of the element i of the externally purchased salt used in the production of the raw materials of the self-produced cathode material and the mass of the element i of the self-produced salt used in the production of the raw materials of the self-produced cathode material. The proportion of the externally purchased salt in the element i of all the salts used in the production of the raw materials of the self-produced cathode material can be expressed as:

[0152]

[0153] where m MSRi is the mass of the i - element of the purchased salt used in producing the raw materials of the self - produced cathode material, with the unit of kg; m MRi is the mass of the i - element of the self - produced salt used in producing the raw materials of the self - produced cathode material, with the unit of kg; y i is the proportion of the purchased salt in the i - element of all the salts used in producing the raw materials of the self - produced cathode material, with the unit of %.

[0154] Exemplarily, when calculating the proportion of recycled materials in the nickel element of the precursor, such as the proportion of recycled materials in the nickel element of nickel - cobalt - manganese hydroxide, that is, the self - produced cathode material raw material is nickel - cobalt - manganese hydroxide and the i - element is the nickel element. Collect the corresponding production material data on the production line for producing this nickel - cobalt - manganese hydroxide, collect the mass of the nickel element of the self - produced salt used, for example, the mass of the nickel element of self - produced nickel sulfate is 433 kg; collect the mass of the nickel element of the purchased salt used, that is, the mass of the nickel element of purchased nickel sulfate is 276 kg; collect the proportion of recycled materials in the nickel element of the purchased salt, provided by the external supplier, for example, the proportion of recycled materials in the nickel element of purchased nickel sulfate is 50%. Then when all the nickel elements of the self - produced nickel sulfate are recycled materials, that is, the proportion of recycled materials in the nickel element of the self - produced salt is 100%. Using the above - mentioned calculation formula for the proportion of recycled materials of the i - element of the self - produced cathode material raw material:

[0155]

[0156] Through the above formula, the proportion of recycled materials in the nickel element of a ternary lithium - ion battery cathode material precursor can be calculated. Similarly, the proportion of recycled materials of the i - element of other self - produced cathode material raw materials can be calculated using the same method.

[0157] In addition, the production material data also includes: the mass of the i - element of the purchased salt used in producing the raw materials of the self - produced cathode material, the recovery rate of the i - element from all salts to the self - produced cathode material raw material, the mass of the i - element of the black powder used in producing the self - produced salt, the recovery rate of the i - element from the black powder to the self - produced salt, and the mass of the i - element in the produced self - produced cathode material raw material.

[0158] Among them, the proportion of the purchased salt in the i - element of all the salts used in producing the raw materials of the self - produced cathode material can also be expressed as:

[0159]

[0161] And, the proportion of self-produced salt in the element i of all salts used when producing the self-produced cathode material raw materials can be expressed as:

[0162]

[0163] In the formula, m Bi Is the mass of element i of the black powder used when producing the self-produced salt, with the unit of kg; v 1i Is the recovery rate of element i from the black powder to the self-produced salt, with the unit of %.

[0164] Exemplarily, there are various ways to obtain the values of v 1i And v 2i It is recommended to use the conventional methods in the field to obtain them. The values of v 1i And v 2i Can be obtained through experiments. The average value of multiple experimental results can also be taken.

[0165] When the proportion of recycled materials in the element i of the self-produced salt is not set to 100%, the calculation formula for the proportion of recycled materials in the element i of the self-produced cathode material raw materials is:

[0166] R Pi = R Mi *y i + R MBi *(1 - y i ),

[0167] Among them, y i Is the proportion of purchased salt in the element i of all salts used when producing the self-produced cathode material raw materials, with the unit of %; (1 - y i ) is the proportion of self-produced salt in the element i of all salts used when producing the self-produced cathode material raw materials, with the unit of %; R Mi Is the proportion of recycled materials in the element i of the purchased salt, with the unit of %; R MBi Is the proportion of recycled materials in the element i of the self-produced salt, with the unit of %; R Pi Is the proportion of recycled materials in the element i of the self-produced cathode material raw materials, with the unit of %.

[0168] Considering that when producing self-produced salt, sometimes the raw materials used are not all recycled materials or recycled raw materials, that is, sometimes virgin ore materials are used. Therefore, the parameter R MBi Is introduced as the proportion of recycled materials in the element i of the self-produced salt, further expanding the application range of the calculation formula for the proportion of recycled materials in the element i of the cathode material raw materials and improving the accuracy of the calculation of the proportion of recycled materials.

[0169] Correspondingly, the proportion of the i element of the externally purchased salt in all the salts used in the production of the self-produced cathode material raw material can be expressed as:

[0170]

[0171] In the formula, m MSRi is the mass of the i element of the externally purchased salt used in the production of the self-produced precursor, in kg; m MRi is the mass of the i element of the self-produced salt used in the production of the self-produced precursor, in kg; y i is the proportion of the externally purchased salt in the i element of all the salts used in the production of the self-produced precursor, in %.

[0172] The proportion of the i element of the externally purchased salt in all the salts used in the production of the self-produced cathode material raw material can be expressed as:

[0173]

[0174] In the formula, m MSRi is the mass of the i element of the externally purchased salt used in the production of the self-produced cathode material raw material, in kg; v 2i is the recovery rate of the i element from all the salts to the self-produced cathode material raw material, in %; m EPi is the mass of the i element in the produced self-produced cathode material raw material, in kg;

[0175] And, the proportion of the i element of the self-produced salt in all the salts used in the production of the self-produced cathode material raw material can be expressed as:

[0176]

[0177] In the formula, m Bi is the mass of the i element of the black powder used in the production of the self-produced salt, in kg; m MSCi is the mass of the i element in the externally purchased material used in the production of the self-produced salt, in kg; v 1i is the recovery rate of the i element from the black powder to the self-produced salt, in %.

[0178] The mass m EPi of the i element in the actually produced self-produced cathode material raw material is actually the mass of the i element in the self-produced cathode material raw material obtained in the process from the black powder to the self-produced salt to the self-produced cathode material raw material.

[0179] During the production process, the production material data further includes: the mass of the i element in the black powder used in the production of the self-produced salt, the mass of the i element in the externally purchased material used in the production of the self-produced salt, and the proportion of the recycled material in the i element of the externally purchased material.

[0180] Among them, the proportion of recycled materials in the i element of the self-produced salt can be expressed as:

Collect the corresponding production material data on the production line for producing this lithium carbonate: Collect the mass of the lithium element of the self-produced salt used, such as the mass of the lithium element of self-produced lithium sulfate is 113 kg; Collect the mass of the lithium element of the purchased salt used, that is, the mass of the lithium element of purchased lithium sulfate is 80 kg; Collect the proportion of recycled materials in the lithium element of the purchased salt, provided by the external supplier, such as the proportion of recycled materials in the lithium element of purchased lithium sulfate is 60%. At the same time, collect the corresponding production material data when producing this self-produced salt, that is, collect the corresponding production material data for producing this self-produced lithium sulfate: Collect the mass of the i element in the black powder used, such as the mass of the lithium element in the black powder is 330 kg; Collect the mass of the i element in the purchased materials used, such as the mass of the lithium element in the purchased materials is 40 kg; Collect the proportion of recycled materials in the i element of the purchased materials, such as the proportion of recycled materials in the lithium element of the purchased materials is 50%. Using the above-mentioned calculation formula for the proportion of recycled materials in the i element of the self-produced cathode material raw material:

[0184]

[0185] Through the above formula, the proportion of recycled materials in the lithium element of the lithium salt can be calculated. Similarly, the proportion of recycled materials in the i element of other self-produced cathode material raw materials can be calculated using the same method.

[0186] It should be noted that all the outputs of the previous process section may be used in the subsequent process section, or only some of the outputs may be used in the subsequent process section. It is necessary to determine the corresponding raw material sources according to the specific products to be accounted for as needed and be flexible. For example, in the process section from black powder to salt, 330 kg of black powder containing lithium element by mass was input, and 40 kg of purchased materials containing lithium element by mass were also input, and about 368.89 kg of self-produced salt containing lithium element by mass was produced. When the subsequent process section only needs 113 kg of self-produced salt containing lithium element by mass, only 113 kg of self-produced salt containing lithium element needs to be taken out from the outputs of the previous process section.

Among them, all the cathode material raw materials used in the production of self-produced cathode materials include self-produced cathode material raw materials and purchased cathode material raw materials.

[0189] Among them, the calculation formula for the proportion of the recycled material in the i element of the self-produced cathode material is:

[0190] R Ci =R Pi *(1 - x i ) + R Wi *x i ;
