[0031] It should be noted that, without conflict, the features in the embodiments of this application can be combined with each other.

[0032] The embodiments of this application provide a method for residual value assessment of a batch of batteries to be recycled. This method can be generated by any electronic device with computing and processing capabilities. The electronic device can be, for example, a computer device facing the terminal or a backend server.

[0033] The following provides a specific example description of the method for residual value assessment of a batch of batteries to be recycled provided by this application through multiple examples in combination with the drawings.

[0034] Figure 1 is one of the flow diagrams of the method for residual value assessment of a batch of batteries to be recycled provided by the embodiments of this application. As Figure 1 shown, this method includes:

[0035] S101. Classify the batch of batteries to be recycled to obtain multiple types of battery objects to be recycled.

[0036] The battery objects to be recycled may include retired power batteries and / or power battery scraps. The multiple types of battery objects to be recycled obtained by classification include multiple types of batteries and / or multiple types of scraps.

[0037] Specifically, the step of classifying the batch of batteries to be recycled to obtain multiple types of battery objects to be recycled may include:

[0038] S201. Classify the retired power batteries in the batch of batteries to be recycled according to multiple preset battery types to obtain multiple types of batteries.

[0039] Among them, the multiple preset battery types include battery packs, battery modules, and battery cells.

[0040] Or, S202. Classify the power battery scraps in the batch of batteries to be recycled according to multiple preset scrap types to obtain multiple types of scraps.

[0041] Among them, the multiple preset waste types include defective batteries, cores, battery cells, positive electrode plates, positive electrode slurries, mud materials, water materials, and positive electrode material powders. Among them, the mud material usually refers to the material with certain plasticity and viscosity after being processed by processes such as mixing and kneading, and the water material refers to the material with water as the solvent or dispersion medium.

[0042] S102. Pretreat various battery objects to be recycled to obtain the recycled materials of various battery objects to be recycled and the mass of the recycled materials.

[0043] After classifying to obtain multiple types of battery objects to be recycled, pretreating various battery objects to be recycled can obtain the recycled materials of various battery objects to be recycled and the mass of the recycled materials, specifically including:

[0044] S301. Determine the target pretreatment method according to the types and categories of various battery objects to be recycled.

[0045] Among them, the type is the positive electrode material type, that is, according to the types of various battery objects to be recycled and the positive electrode material type, determine the target pretreatment method. The positive electrode material type can include, for example, lithium-ion positive electrode materials, sodium-ion positive electrode materials, etc.

[0046] S302. Use the target pretreatment method to pretreat various battery objects to be recycled to obtain the recycled materials of various battery objects to be recycled.

[0047] After determining the target pretreatment method, use the target pretreatment method to pretreat various battery objects to be recycled. Among them, various battery objects to be recycled include retired power batteries and / or power battery wastes. Then the pretreatment can be, for example, disassembling and separating the retired power batteries or power battery wastes, including but not limited to operations such as removing the outer shell, separating the battery cells, separating the electrodes and diaphragms, etc.; or, crushing and sorting the retired power batteries or power battery wastes, including but not limited to mechanical crushing, pyrolytic crushing, etc. After pretreatment, the recycled materials of the retired power batteries or power battery wastes can be obtained, and the recycled materials are weighed to obtain the mass m of the recycled materials. p . Among them, the positive electrode slurries, mud materials, water materials, and positive electrode material powders in the power battery wastes do not need to be disassembled and separated by operations such as removing the outer shell, separating the battery cells, separating the electrodes and diaphragms, etc., nor do they need to be crushed and sorted by operations such as mechanical crushing, pyrolytic crushing, etc.

[0048] S103. Detect the metal content of the recycled materials of various battery objects to be recycled to obtain the metal detection results of various battery objects to be recycled.

[0049] The detection of metal content can be achieved by instrumental analysis methods and chemical analysis methods. The obtained metal detection results include the content parameters of valuable metals and the content parameters of non-valuable metals. Among them, valuable metals refer to the metals with high economic value and recycling value in the battery, and non-valuable metals usually refer to the metals that exist in the battery but have relatively low economic value, or under the current technical and market conditions, have high recycling costs, great recycling difficulties, and no obvious recycling economic benefits.

[0050] For example, using atomic absorption spectrometry (AAS): Based on the absorption intensity of the outer electrons of gaseous ground-state atoms for the corresponding atomic resonance radiation lines in the ultraviolet and visible light ranges to quantitatively determine the content of the element to be measured. The sample needs to be pretreated first, such as taking out the relevant materials in the battery, grinding, pulverizing, mixing with an appropriate amount of acid or alkali, heating and stirring to dissolve the metal ions, centrifuging to remove insoluble substances, and then performing the determination. Each metal has a specific wavelength, and the content of the metal, including the content parameters of valuable metals and the content parameters of non-valuable metals, is determined by the degree of light absorption when the light beam passes through the atomic vapor containing the metal.

[0051] Atomic emission spectrometry (AES): Using the characteristic spectra emitted by atoms after being excited to determine the types and contents of elements in the sample. It can perform qualitative and quantitative analysis on multiple metal elements simultaneously, with high sensitivity and can detect low-content metals.

[0052] X-ray fluorescence spectrometry (XRF): Using a handheld or desktop XRF analyzer, when X-rays irradiate the sample, the atoms in the sample will absorb the X-ray energy and emit characteristic fluorescent X-rays. By detecting the energy and intensity of the fluorescent X-rays, the types and contents of elements are determined. It does not require complex sample pretreatment and can directly analyze samples such as solids and powders, and can quickly obtain semi-quantitative or quantitative results of multiple metal elements, and is often used for on-site rapid detection and screening.

[0053] Inductively coupled plasma mass spectrometry (ICP-MS): Converting the sample into a plasma state to ionize the metal ions in it, and then determining the types and contents of elements by detecting the mass-to-charge ratio and intensity of the ions through a mass spectrometer. It has extremely high sensitivity, can detect extremely low-content metal elements, can analyze multiple elements simultaneously, and can also perform isotope analysis, but the instrument is expensive and the operating cost is high.

[0054] Inductively coupled plasma optical emission spectrometry (ICP-OES): Introducing the sample into an inductively coupled plasma to excite the atoms and ions in the sample to emit characteristic spectra, and determining the content of the element according to the intensity and wavelength of the spectra. It can simultaneously determine the contents of multiple metal elements, has a wide linear range and high precision, and is often used to detect the metal content in battery materials such as lithium iron phosphate cathode waste powder.

[0055] S104. Evaluate the residual value of the batch of batteries to be recycled based on the metal detection results of various types of batteries to be recycled and the quality of the corresponding recycled materials, and obtain the residual value evaluation parameters of the batch of batteries to be recycled.

[0056] After obtaining the quality of the recycled materials of various types of batteries to be recycled according to step S102 and the metal detection results of various types of batteries to be recycled according to step S103, the residual value of the batch of batteries to be recycled can be evaluated to obtain the residual value evaluation parameters of the batch of batteries to be recycled, specifically including:

[0057] S401. Evaluate the residual value of each type of battery to be recycled separately based on the content parameters of valuable metals, the content parameters of non-valuable metals, the quality of the corresponding recycled materials, and the quality of various types of batteries to be recycled, and obtain the residual value of each type of battery to be recycled.

[0058] S402. Obtain the residual value evaluation parameters of the batch of batteries to be recycled based on the residual value of each type of battery to be recycled.

[0059] After obtaining the residual value of each type of battery to be recycled, the residual value evaluation parameters of the batch of batteries to be recycled can be obtained. Moreover, a residual value evaluation report can be generated according to the residual value evaluation parameters, so as to facilitate the user to intuitively obtain the residual value evaluation parameters.

[0060] In summary, this embodiment provides a method for evaluating the residual value of a batch of batteries to be recycled, which can evaluate the residual value of the batch of batteries to be recycled based on the metal detection results of various types of batteries to be recycled and the quality of the corresponding recycled materials, obtain the residual value evaluation parameters of the batch of batteries to be recycled, accurately measure the resource value of the batteries to be recycled, and promote the efficient recycling of resources.

[0061] Figure 5 This is the fifth flow chart of the method for evaluating the residual value of a batch of batteries to be recycled provided by the embodiment of the present application. As Figure 5 shown, step S401 may specifically include:

[0062] S501. Calculate the price correction coefficient of the valuable metals corresponding to each type of battery to be recycled based on the content parameters of valuable metals, the content parameters of non-valuable metals, the quality of the corresponding recycled materials, and the quality of various types of batteries to be recycled.

[0063] Specifically, the first formula can be used to calculate the price correction coefficient of the valuable metals corresponding to each type of battery to be recycled. The first formula is as follows:

[0064]

[0065] where d iis the price correction coefficient of the valuable metals corresponding to the various types of batteries to be recycled, m c is the mass of the various types of batteries to be recycled, m p is the mass of the recycling treatment materials corresponding to the various types of batteries to be recycled; c i is the content parameter of the valuable metals corresponding to the various types of batteries to be recycled; c j is the content parameter of the non-valuable metals corresponding to the various types of batteries to be recycled;

[0066] Alternatively, use the second formula to calculate the price correction coefficient of the valuable metals corresponding to the various types of batteries to be recycled. The second formula is as follows:

[0067]

[0068] where d i is the price correction coefficient of the valuable metals corresponding to the various types of batteries to be recycled, m c is the mass of the various types of batteries to be recycled, m p is the mass of the recycling treatment materials corresponding to the various types of batteries to be recycled; c i is the content parameter of the valuable metals corresponding to the various types of batteries to be recycled; c j is the content parameter of the non-valuable metals corresponding to the various types of batteries to be recycled, k is the type influence factor of the various types of batteries to be recycled, and s is the appearance influence factor of the various types of batteries to be recycled.

[0069] In practical applications, the first formula or the second formula can be determined according to the actual recycling requirements. This application does not limit the application scope of the first formula and the second formula.

[0070] S502. Calculate the residual value of each type of battery to be recycled according to the content parameter of the valuable metal, the mass of the corresponding recycling treatment material, and the price correction coefficient of the valuable metal corresponding to each type of battery to be recycled.

[0071] After obtaining the price correction coefficient of the valuable metal according to the first formula or the second formula, the residual value of each type of battery to be recycled can be calculated. S502 specifically includes:

[0072] S601. Calculate the residual value of the valuable metals of each type of battery to be recycled according to the content parameter of the valuable metal, the mass of the corresponding recycling treatment material, and the price correction coefficient of the valuable metal corresponding to each type of battery to be recycled.

[0073] The content parameter of the valuable metal is c i , and the mass of the corresponding recycling treatment material is m p, the price correction coefficient of the valuable metals corresponding to various battery objects to be recycled is d i , and based on these three parameters, calculate the residual value V of the valuable metals of various battery objects to be recycled x .

[0074] S602. Determine the residual value of each battery object to be recycled according to the residual value of the valuable metals of each battery object to be recycled.

[0075] Then, according to the residual value of the valuable metals of each battery object to be recycled, the residual value of each battery object to be recycled can be determined.

[0076] Figure 7 This is the seventh flow chart of the residual value evaluation method for the batch of batteries to be recycled provided by the embodiment of the present application. As Figure 7 shown, before performing step S602, the method of the present application may further include:

[0077] S701. Determine the price correction coefficient of the non-valuable metals corresponding to various battery objects to be recycled according to the processing cost of the non-valuable metals.

[0078] S702. Calculate the non-valuable metal residual value of various battery objects to be recycled according to the content parameter of the non-valuable metals, the quality of the corresponding recycled material, and the price correction coefficient of the non-valuable metals corresponding to various battery objects to be recycled.

[0079] S703. Calculate the residual value of the removed metals of various battery objects to be recycled according to the quality of the removed metals corresponding to various battery objects to be recycled and the price depreciation coefficient of the removed metals.

[0080] Among them, the removed metals corresponding to various battery objects to be recycled mainly refer to the metal materials with recycling value disassembled from the battery components during the battery recycling process. The following are some common removed metals in the batteries to be recycled and their related introductions:

[0081] Copper: Copper in the battery mainly exists in the current collector and connecting parts of the electrode. Copper has good electrical conductivity and thermal conductivity, and is used for transmitting current and dissipating heat. Recycling copper is a common metal recycling activity because copper has wide applications in many fields such as electrical, electronic, and construction.

[0082] Aluminum: Aluminum is usually used in parts such as the battery shell and electrode current collector. Aluminum has the advantages of light weight, corrosion resistance, and good electrical conductivity. Recycling aluminum can save a large amount of energy and resources because the production of aluminum requires a large amount of electrical energy.

[0083] By effectively removing and recycling these metals above, the recycling of resources can be realized, environmental pollution can be reduced, and at the same time, it also has certain economic value.

[0084] Then, determining the residual value of each type of battery to be recycled according to the residual value of valuable metals in each type of battery to be recycled includes the following situations:

[0085] 1. Determining the residual value of each type of battery to be recycled according to the residual value of valuable metals in each type of battery to be recycled.

[0086] In one implementation, determining the residual value of each type of battery to be recycled according to the residual value of valuable metals in each type of battery to be recycled may include:

[0087] (1) Information collection

[0088] First, obtain the information of the battery to be recycled, including the battery codes (mud and water materials do not have battery codes), types, categories, appearances, and total masses of waste batteries and some waste materials, classify the waste batteries and waste materials, and weigh each type of battery to be recycled (waste batteries and waste materials) to obtain the corresponding mass m cx .

[0089] (2) Pretreatment

[0090] Then, according to the above classification of waste batteries and waste materials, select corresponding treatment processes for various types of waste batteries and waste materials, and record the mass m of the corresponding recycled and treated materials obtained after treatment p , and according to different types of waste batteries and waste materials m p can be m p1 , m p2 , m p3 ,...m px .

[0091] (3) Metal content detection

[0092] Based on the recycled and treated materials obtained from the pretreatment, detect the percentage content of each metal element in the recycled and treated materials to obtain the percentage content c of valuable metal i i1 , c i2 , c i3 ,...c ix and the percentage content c of non-valuable metal j j1 , c j2 , c j3 ,...c jx .

[0093] According to the metal detection results, collect the price P of the corresponding valuable metal i i ; according to the recycled and treated materials obtained from different types of waste batteries and waste materials P i can be P i1 , P i2 , P i3 ,...P ix .

[0094] (4) Residual value assessment

[0095] According to m in the above steps cx 、m px 、P ix 、c ix and c jx , and the residual value formula of battery recovery quantity: Calculate the residual value of various battery objects to be recycled, where n is the number of types of valuable metals in various battery objects to be recycled; and according to the formula Calculate the residual value of the batch of batteries to be recycled, where y is the number of types of battery objects to be recycled in the batch of batteries to be recycled.

[0096] In another implementation, according to the residual value of valuable metals of various battery objects to be recycled, determining the residual value of various battery objects to be recycled may include:

[0097] (1) Information collection

[0098] First, obtain the information of the battery objects to be recycled, including the battery codes, types, categories, appearances, and total masses of waste batteries and scraps, classify the waste batteries and scraps, and weigh various battery objects to be recycled (waste batteries and scraps) to obtain the corresponding mass m cx .

[0099] According to the classification of waste batteries and scraps, analyze and obtain the influence factor k of the corresponding types of waste batteries and scraps. The value of k is 0 < k ≤ 1. According to different types of waste batteries and scraps, k can be k1, k2, k3,... k x ; The types of waste batteries include battery cells, battery modules, and battery packs, etc. The types of scraps include mud, water material, cathode material powder, cathode slurry, cathode electrode sheet, core, cell, etc. As the composition integrity of the types of waste batteries and scraps increases, the difficulty of recycling and disassembling gradually increases, and the k value is smaller; conversely, the k value is larger.

[0100] Among them, compared with battery cells, battery modules, and battery packs, cathode material powder and cathode slurry do not need to be disassembled, discharged, and crushed, so their k values are closer to 1.

[0101] According to different types of waste batteries and scraps, analyze and obtain the appearance influence factor s of the corresponding types of waste batteries and scraps. The value of s is 0 < s ≤ 1. According to different types of waste batteries and scraps, s can be s1, s2, s3,... s x; The appearance impacts of waste batteries and scraps include the degree of damage of retired batteries and defective batteries, and the impacts on the safety of the disassembly process and storage safety. The higher the safety impact, the smaller the s value; conversely, the larger the s value. It also includes the storage difficulty of waste batteries and scraps. For example, the storage difficulty of liquid waste batteries and scraps, semi-solid waste batteries and scraps, and solid waste batteries and scraps gradually decreases, and the s value gradually increases.

[0102] Among them, compared with the positive electrode plate, wound core, battery cell, battery module, and battery pack, waste batteries and scraps in the form of slurry and mud are more difficult to store. Therefore, the s value of slurry and mud is closer to 0.

[0103] (2) Pretreatment

[0104] According to the above classification of waste batteries and scraps, corresponding treatment processes are selected for various types of waste batteries and scraps, and the mass m of the corresponding recycled and treated materials obtained after treatment is recorded. p , according to different types of waste batteries and scraps m p can be m p1 、m p2 、m p3 、...m px .

[0105] (3) Metal content detection

[0106] Based on the recycled and treated materials obtained from pretreatment, the percentage content of each metal element in the recycled and treated materials is detected to obtain the percentage content c of valuable metal i i1 、c i2 、c i3 、...、c ix and the percentage content c of non-valuable metal j j1 、c j2 、c j3 、...c jx .

[0107] According to the metal detection results, the price P of the corresponding valuable metal i is collected i ; The P of the recycled and treated materials obtained from different types of waste batteries and scraps i can be P i1 、P i2 、P i3 、...P ix .

[0108] (4) Residual value assessment

[0110] 2. Or, determine the residual value of various battery objects to be recycled according to the valuable metal residual value and non-valuable metal residual value of various battery objects to be recycled.

[0111] In one implementation, determining the residual value of various battery objects to be recycled according to the valuable metal residual value and non-valuable metal residual value of various battery objects to be recycled may include:

[0112] (1) Information collection

[0113] First, obtain the information of the battery objects to be recycled, including the battery codes, types, categories, appearances, and total masses of waste batteries and scraps, classify the waste batteries and scraps, and weigh the battery objects to be recycled to obtain the corresponding mass m cx .

[0114] According to the classification of waste batteries and scraps, analyze and obtain the influence factor k of the corresponding types of waste batteries and scraps. The value of k is 0 < k ≤ 1. According to different types of waste batteries and scraps, k can be k1, k2, k3,... k x ; The types of waste batteries and scraps include mud, water, positive electrode material powder, positive electrode paste, positive electrode sheet, core, battery cell, battery module, and battery pack, etc. As the composition integrity of the types of waste batteries and scraps increases, the difficulty of recycling and disassembling gradually increases, and the k value is smaller; on the contrary, the k value is larger.

[0115] Among them, compared with battery cells, battery modules, and battery packs, positive electrode material powder and positive electrode paste do not need to be disassembled, discharged, and crushed, so their k values are closer to 1.

[0116] According to different types of waste batteries and scraps, analyze and obtain the appearance influence factor s of the corresponding types of waste batteries and scraps. The value of s is 0 < s ≤ 1. According to different types of waste batteries and scraps, s can be s1, s2, s3,... s xThe appearance impacts of waste batteries and waste materials include the degree of damage of retired batteries and defective batteries, the impacts on the safety of the disassembly process and storage safety. The higher the safety impact, the smaller the s value; conversely, the larger the s value. It also includes the storage difficulty of other waste materials. The storage difficulty of liquid waste batteries and waste materials, semi-solid waste batteries and waste materials, and solid waste batteries and waste materials gradually decreases, and the s value gradually increases.

[0117] Among them, compared with the positive electrode sheet, core, battery cell, battery module, and battery pack, waste batteries and waste materials in the state of water materials and mud materials are more difficult to store. Therefore, the s of water materials and mud materials is closer to 0.

[0118] (2) Pretreatment

[0119] According to the above classification of waste batteries and waste materials, corresponding treatment processes are selected for various types of waste batteries and waste materials, and the quality m of the corresponding recycled and treated materials obtained after treatment is recorded. p , according to different types of waste batteries and waste materials m p can be m p1 , m p2 , m p3 ,...m px .

[0120] (3) Metal content detection

[0121] Based on the recycled and treated materials obtained from pretreatment, the percentage content of each metal element in the recycled and treated materials is detected to obtain the percentage content c of valuable metal i i1 , c i2 , c i3 ,...,, c ix and the percentage content c of non-valuable metal j j1 , c j2 , c j3 ,...c jx .

[0122] According to the metal detection results, the prices P of the corresponding valuable metal i and non-valuable metal j are collected i and P j ; the P of the recycled and treated materials obtained from different types of waste batteries and waste materials i can be P i1 , P i2 , P i3 ,...P ix , P j can be P j1 , P j2 , P j3 ,...P jx .
