[0002] With the rapid development of battery technology, lithium batteries have become an indispensable part of the markets for new energy vehicles, electric bicycles, drones, energy storage, battery packs, portable electronic products, etc. In the production process of lithium batteries, not only technical routes and cost control should be considered, but also sustainable development and environmental protection. Carbon emissions are one of the important indicators for measuring sustainable development and environmental protection. The relevant technology mainly uses a method based on literature values ​​and test values ​​to estimate carbon emissions generated in the production process of lithium battery positive electrode materials. Due to differences in production conditions, raw material sources, and equipment efficiency, the carbon emission estimation results based on literature values ​​and test values ​​of historical data may not reflect changes in current production technology and energy structure, resulting in a large error between the actual emissions and the estimated values. There is a technical problem that the accuracy of the calculation results of carbon emissions in the production process of lithium battery positive electrode materials is not ideal.

[0003] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0023] Emission Factor is a key parameter used to quantify greenhouse gas emissions generated by a specific activity, process or energy use. It is usually defined as the greenhouse gas emissions per unit of activity or consumption. Emission Factor plays a central role in calculating carbon footprint, greenhouse gas emissions, environmental impact analysis and developing climate change mitigation strategies.

[0024] Sintering is a heat treatment process that is used to heat powdered raw materials to bond their particles, thereby forming a solid material with a certain strength and structure. It is widely used in ceramics, powder metallurgy, electronic materials, lithium battery positive electrode materials and other fields.

[0025] GWP (Global Warming Potential) is an indicator used to measure the impact of different greenhouse gases on global warming. It compares the relative contribution of a unit mass of greenhouse gas to the same mass of carbon dioxide (CO2) to global warming within a specific period of time.

[0026] The prior art provides a method for calculating carbon emissions based on coal-fired power generation. First, according to the monthly average elemental carbon content of coal combustion and the annual coal consumption, the slag, fly ash production, average carbon content, and annual consumption of desulfurizer are obtained. Secondly, the net purchased electricity is obtained, and the carbon emissions generated during the combustion of coal, desulfurizer and electricity consumption are calculated respectively according to the carbon dioxide emissions. Finally, the total carbon emissions generated in the coal-fired power generation process are obtained. The above method mainly determines the total carbon emissions through carbon dioxide emissions generated by coal combustion and electricity use, but for the battery production process, it also includes other sources of carbon emissions such as sintering and equipment escape, and other greenhouse gases such as methane and nitrous oxide are also produced. Therefore, the above method cannot accurately solve the carbon emissions in the battery production process.

[0027] According to an embodiment of the present application, a method embodiment of a method for determining carbon emissions in a battery production process is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0028] Figure 1 is a flow chart of an optional method for determining carbon emissions in a battery production process provided in an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0029] Step S102, determining the amount of fugitive emissions of gas emitted from the environmental control equipment based on equipment information of the environmental control equipment used in the battery production process;

[0030] It is understandable that the equipment information of the environmental control equipment used in the battery production process to control the production environment state (such as temperature, humidity, etc.), such as the number of equipment, equipment type, etc., is obtained. Based on the above equipment information, the fugitive emissions of the gas emitted by the environmental control equipment are determined. By obtaining the equipment information of the environmental control equipment, the fugitive emissions of the gas emitted by the environmental control equipment can be accurately calculated. Based on the data analysis of fugitive emissions, high-risk equipment or links can be identified, and more environmentally friendly alternative materials or equipment can be adopted, thereby continuously improving the carbon footprint management of the production process.

[0031] Optionally, fugitive emissions refer to the non-combustion direct release of greenhouse gases caused by equipment leakage, material volatilization, or specific process during the production process. Environmental control equipment used in the battery production process includes refrigeration equipment, fire extinguishing equipment, etc. Refrigeration equipment is used to control the temperature and humidity conditions during the production process, as well as to cool the production equipment. Fire extinguishing equipment is used to prevent fire risks during the battery production process and protect production equipment and materials, as well as the safety of personnel.

[0032] In an optional embodiment, based on the equipment information of the environmental control equipment used in the battery production process, the fugitive emissions of the gas emitted by the environmental control equipment are determined, including: determining the equipment quantity of the environmental control equipment based on the equipment information; determining a first emission factor corresponding to the environmental control equipment, wherein the first emission factor is used to represent the amount of carbon emissions generated by the escape of a unit of gas from the environmental control equipment; and determining the fugitive emissions according to the equipment quantity and the first emission factor.

[0033] It can be understood that the number of environmental control equipment is determined based on the equipment information of the environmental control equipment used in the battery production process. The first emission factors corresponding to different types of environmental control equipment are determined, wherein the first emission factor is used to represent the size of the carbon emissions caused by the unit gas escape of the environmental control equipment. Based on the number of equipment and the first emission factor, the fugitive emissions in the battery production process are determined. By calculating and analyzing the fugitive emissions of environmental control equipment in detail, the comprehensiveness of carbon emission accounting is ensured, and the accuracy and reliability of the calculation of total carbon emissions are improved. At the same time, the hot spots and equipment of fugitive emissions can be identified, and targeted improvement measures can be taken, such as upgrading equipment, strengthening maintenance, optimizing operation strategies, etc., so as to reduce greenhouse gas emissions and achieve the goals of energy conservation, emission reduction and environmentally friendly production.

[0034] Optionally, the formula for calculating fugitive emissions from environmental control equipment is as follows:

[0035] E 逸散 =∑ k [(Num k ×EF 逸散，k )×GWP k ]

[0036] Among them, E 逸散 Indicates the fugitive emissions of environmental control equipment, in tCO2e (tons of carbon dioxide equivalent); Num k Indicates the number of equipment type k; EF 逸散，k represents the greenhouse gas fugitive emission factor (i.e. the first emission factor) of equipment type k; GWP k Represents the global warming trend of greenhouse gases for device type k.

[0037] In an optional embodiment, fugitive emissions are determined according to the number of equipment and a first emission factor, including: when the environmental control equipment includes a refrigeration equipment, based on the type of refrigerant used in the refrigeration equipment, determining the first emission factor corresponding to the refrigeration equipment; determining the refrigeration fugitive emissions according to the number of refrigeration equipment and the first emission factor corresponding to the refrigeration equipment; and obtaining the fugitive emissions based on the refrigeration fugitive emissions.

[0038] It can be understood that if the environmental control equipment used in the battery production process includes refrigeration equipment, the first emission factor corresponding to the refrigeration equipment is determined according to the type of refrigerant used in the refrigeration equipment. The first emission factor corresponding to the above refrigeration equipment reflects the average escape rate of the refrigerant during the use of the equipment. The number of refrigeration equipment is obtained, and the refrigeration fugitive amount of the refrigeration equipment is determined based on the number of equipment and the first emission factor corresponding to the refrigeration equipment. Based on the refrigeration fugitive amount of the above refrigeration equipment, the fugitive emissions in the battery production process are determined. By accurately measuring the fugitive emissions of the refrigerant of each refrigeration equipment, it is possible to achieve refined management of fugitive emissions, which helps to more accurately evaluate its carbon assets, and is crucial for rationally planning carbon emissions and achieving energy conservation and emission reduction goals.

[0039] Optionally, the amount of refrigeration dissipation generated by the refrigeration equipment is not only related to the type of refrigerant, but also to the state and aging degree of the refrigeration equipment. The first is the decline in the equipment performance of the refrigeration equipment. As the equipment ages, the equipment efficiency and sealing performance may decline, resulting in an increase in the amount of refrigeration dissipation of the refrigeration equipment. Secondly, as the equipment ages, the maintenance frequency of the equipment will also increase. If the maintenance is improper, such as the sealing ring is worn and not replaced in time, and the refrigerant leakage is not adequately detected, etc., it will lead to an increase in the amount of refrigeration dissipation. Finally, aging equipment may face higher operating risks, including accidental leaks and failures, which will not only increase the amount of refrigeration dissipation, but also pose a threat to the environment and human health.

[0040] Optionally, during the battery production process, dehumidification equipment can be used to control the humidity of the production environment to reduce the ambient humidity and protect the chemical stability of battery materials and components, thereby improving the performance and safety of the battery and extending the battery life. For dehumidification equipment that includes a heat pump system, fugitive emissions will also be generated due to the use of refrigerants. The emissions generated are related to the type of refrigerant, the state of the dehumidification equipment, and the degree of aging.

[0041] In an optional embodiment, the fugitive emissions are determined according to the number of equipment and the first emission factor, including: when the environmental control equipment includes a fire extinguishing equipment, based on the type of fire extinguishing material used by the fire extinguishing equipment, determining the fire extinguishing fugitive emissions according to the number of fire extinguishing equipment and the first emission factor corresponding to the fire extinguishing equipment; and obtaining the fugitive emissions based on the fire extinguishing fugitive emissions.

[0042] It can be understood that if the environmental control equipment used in the battery production process includes fire extinguishing equipment, the first emission factor corresponding to the fire extinguishing equipment is determined according to the type of fire extinguishing material used in the fire extinguishing equipment. The first emission factor corresponding to the above-mentioned fire extinguishing equipment reflects the average escape rate of the fire extinguishing material during the use of the equipment. The number of fire extinguishing equipment is obtained, and the fire extinguishing emission of the fire extinguishing equipment is determined based on the number of equipment and the first emission factor corresponding to the fire extinguishing equipment. Based on the fire extinguishing emission of the above-mentioned fire extinguishing equipment, the fugitive emissions in the battery production process are determined. The fugitive emissions of the fire extinguishing equipment are calculated by the emission factor of a specific fire extinguishing material, which improves the accuracy of the emission calculation. At the same time, after determining the emission of the fire extinguishing equipment, targeted emission reduction measures can be taken according to the actual emission situation, such as replacing low-GWP fire extinguishing materials, improving equipment sealing, strengthening maintenance inspections, etc., to reduce the escape of fire extinguishing materials.

[0043] Step S104, obtaining production-related emissions during the battery production process;

[0044] It is understandable that the production emissions in the battery production process, such as sintering emissions, fossil fuel emissions and electricity emissions, are obtained. The calculation of production emissions covers all aspects of the battery production process. By calculating production emissions, various types of carbon emissions in the battery production process can be comprehensively and accurately calculated, which improves the accuracy of carbon emission accounting.

[0045] In an optional embodiment, production emissions include sintering emissions, and obtaining production emissions in the battery production process includes: obtaining the raw material consumption of lithium salt in the battery production process; determining the sintering completion rate of the lithium salt and the relative mass fraction of carbon dioxide produced by the lithium salt in the sintering reaction, wherein the sintering completion rate is used to indicate the degree of completion of the sintering reaction, and the relative mass fraction of carbon dioxide indicates the ratio of the molecular mass of carbon dioxide to the molecular mass of lithium salt; determining the sintering emissions based on the raw material consumption, the sintering completion rate, and the relative mass fraction of carbon dioxide.

[0046] It can be understood that since the sintering reaction in the production process of the battery will produce gases such as carbon dioxide (CO2), causing carbon emissions, the production emissions include sintering emissions. In order to calculate the sintering emissions, it is first necessary to obtain the raw material consumption of the lithium salt used in the production process of the battery. Secondly, based on experimental analysis or production process detection, the sintering completion rate of the lithium salt during the sintering process and the relative mass fraction of carbon dioxide generated during the sintering process are determined. Among them, the above-mentioned sintering completion rate is an indicator for indicating the degree of completion of the sintering process, that is, the percentage value of the lithium salt participating in the chemical reaction, and the relative mass fraction of carbon dioxide indicates the proportion of the molecular mass of carbon dioxide generated during the sintering reaction to the molecular mass of the lithium salt. Based on the raw material consumption of lithium salts in the battery production process, the sintering completion rate, and the relative mass fraction of carbon dioxide, the sintering emissions generated by the battery sintering process are calculated. By directly obtaining the raw material consumption, measuring the sintering completion rate and the relative mass fraction of carbon dioxide, the sintering emissions can be accurately calculated, avoiding the calculation errors caused by using empirical data or literature values. At the same time, accurate calculation of sintering emissions helps to identify high-emission links in the production process. By optimizing the sintering process (such as adjusting the temperature, time, and raw material ratio) and improving equipment (such as improving energy efficiency and reducing raw material waste), the goals of energy conservation and emission reduction can be achieved, the total carbon emissions can be reduced, and the environmental protection and economy of the production process can be improved.

[0047] Optionally, the sintering emissions are calculated as follows:

[0048] E 烧结 =∑ p ∑ q AD 锂盐p,q ×η p,q ×F p,q

[0049] Among them, E 烧结 Indicates the sintering emissions generated during the sintering process, in tCO2; AD 锂盐p,q represents the consumption of the pth batch of lithium salt raw material q (i.e. raw material consumption), in units of t (tons); η p,q represents the sintering completion rate of the pth batch of lithium salt raw material q, and the sintering completion rate of the lithium salt raw material can be determined by electrochemical analysis or thermogravimetric analysis; F p,q It represents the relative mass fraction of carbon dioxide produced by the sintering chemical reaction of the pth batch of lithium salt raw material q. For example, the relative mass fraction of carbon dioxide produced by the sintering chemical reaction of lithium carbonate is 44 / 74.

[0050] In an optional embodiment, production emissions include fossil fuel emissions, and obtaining production emissions in the battery production process includes: obtaining the fossil fuel consumption in the battery production process; determining the multiple types of gases produced by fossil fuels; and determining the fossil fuel emissions based on the second emission factors corresponding to the multiple types of gases and the fossil fuel consumption, wherein the second emission factor is used to represent the amount of carbon emissions caused by the combustion of a unit of fossil fuel.

[0051] It can be understood that in the battery production process, fossil fuels are mainly used in transportation equipment and boilers, so production emissions include fossil fuel emissions. In order to calculate fossil fuel emissions, it is first necessary to obtain the fossil fuel consumption of the battery in the production process. Secondly, determine the various types of gases produced during the combustion of fossil fuels, such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), etc. According to the various gas types, determine the second emission factors corresponding to the various gas types, wherein the second emission factor is used to indicate the size of the carbon emissions caused by the combustion of a unit of fossil fuel. Based on the second emission factors and fossil fuel consumption corresponding to the above-mentioned various gas types, the fossil fuel emissions generated by the battery production process are calculated. Through the above steps, the carbon emissions caused by the combustion of fossil fuels in the battery production process can be accurately quantified, which helps to identify the high-emission energy use links in the battery production process, and then measures can be taken to optimize the energy structure and efficiency, such as switching to clean energy, upgrading energy utilization equipment, etc., to reduce carbon emissions and energy consumption, and achieve sustainable development.

[0052] Alternatively, fossil fuel emissions are calculated as follows:

[0053] E 燃烧 =E 二氧化碳 +E 甲烷 +E 氧化亚氮

[0054] Among them, E 燃烧 Represents the fossil fuel emissions from the combustion of fossil fuels, in tCO2e; E 二氧化碳 It represents the direct carbon dioxide emissions from the combustion of fossil fuels, in tCO2e; E 甲烷 It represents the direct methane emissions from fossil fuel combustion, in tCO2e; E 氧化亚氮 It represents the direct nitrous oxide emissions from fossil fuel combustion, in tCO2e.

[0055] The formula for calculating direct carbon dioxide emissions from fossil fuel combustion is as follows:

[0056] E 二氧化碳 =∑ n AD 燃料×EF 二氧化碳 ×GWP 二氧化碳

[0057] Among them, AD 燃料 Indicates the amount of fossil fuels (i.e. fossil fuel consumption), in tons; EF 二氧化碳 Indicates the emission factor of carbon dioxide produced by the combustion of fossil fuels (i.e. the second emission factor corresponding to carbon dioxide), the unit is tCO2 / t (tons of carbon dioxide / ton); GWP 二氧化碳 represents the global warming potential of carbon dioxide; n represents the type of fossil fuel.

[0058] The calculation formula for the emission factor of carbon dioxide (i.e. the second emission factor corresponding to carbon dioxide) is as follows:

[0059]

[0060] Among them, CC i,j represents the carbon content of fossil fuel j in facility i; OF i,j represents the carbon oxidation rate of the combustion of fossil fuel j in facility i; It expresses the ratio of the relative molecular mass of carbon dioxide to carbon.

[0061] The formula for calculating direct methane emissions from fossil fuel combustion is as follows:

[0062] E 甲烷 =∑ n AD 燃料 ×EF 甲烷 ×GWP 甲烷

[0063] Among them, EF 甲烷 It represents the emission factor of methane produced by the combustion of fossil fuels (i.e. the second emission factor corresponding to methane), with the unit of tCH4 / t (tons of methane / ton); GWP 甲烷 represents the global warming potential of methane; n represents the type of fossil fuel.

[0064] The direct nitrous oxide emissions from fossil fuel combustion are calculated as follows:

[0065] E 氧化亚氮 =∑ n AD 燃料 ×EF 氧化亚氮 ×GWP 氧化亚氮

[0066] Among them, EF 氧化亚氮 It represents the emission factor of nitrous oxide produced by the combustion of fossil fuels (i.e. the second emission factor corresponding to nitrous oxide), with the unit of tN2O / t (tons of nitrous oxide / ton); GWP 氧化亚氮represents the global warming potential of nitrous oxide; n represents the type of fossil fuel.

[0067] In an optional embodiment, production emissions include electricity emissions, and obtaining production emissions in the battery production process includes: obtaining the electricity consumption used in the battery production process; determining a third emission factor corresponding to the power grid in the area where the batteries are produced, wherein the third emission factor is used to represent the amount of carbon emissions caused by unit electricity produced by the regional power grid; and determining electricity emissions based on the electricity consumption and the third emission factor.

[0068] It can be understood that since the battery production process involves the use of various types of production equipment, office equipment and environmental control equipment, production emissions include electricity emissions. In order to calculate electricity emissions, it is first necessary to obtain the electricity consumption used by the battery in the production process. Secondly, determine the power generation method of the power grid in the area where the battery is produced (such as coal power generation, thermal power generation and clean energy power generation, etc.), and based on the power generation method, determine the third emission factor corresponding to the power grid in the area where the battery is produced, where the third emission factor is used to represent the amount of carbon emissions caused by the unit electricity produced by the regional power grid. Based on the electricity consumption and the third emission factor, calculate the electricity emissions generated by the battery production process. By obtaining the actual electricity consumption and the third emission factor corresponding to the power grid in the area where the battery is produced, the accuracy of the calculation results of the electricity carbon emissions is significantly improved, thereby improving the accuracy of the total carbon emissions caused by the battery production process, providing reliable data support for carbon asset management.

[0069] Optionally, the calculation formula for electricity emissions is as follows:

[0070] E 电力 =AD 电力 ×EF 电力

[0071] Among them, E 电力 Indicates the carbon emissions generated by purchased electricity, in tCO2; AD 电力 Indicates the amount of electricity purchased (i.e. electricity consumption), in MWh (megawatt-hours); EF 电力 It represents the average emission factor of the regional power grid (i.e. the third emission factor), with the unit of tCO2 / MWh (tons of carbon dioxide / megawatt hour).

[0072] Step S106, determining the total carbon emissions in the battery production process based on the fugitive emissions and the production emissions.

[0073] It can be understood that the total carbon emissions generated by the battery production process are determined based on the fugitive emissions and production emissions caused by environmental control equipment in the battery production process. By considering the fugitive emissions and production emissions in the battery production process, the comprehensive calculation of carbon emissions is ensured, and the omissions in the emission calculation are avoided, thereby providing more comprehensive carbon emission information, providing data support for long-term emission reduction plans, and helping to formulate more reasonable and effective emission reduction targets and action plans, promoting the production process to develop in a low-carbon and environmentally friendly direction, and achieving sustainable production.

[0074] Optionally, the total carbon emissions are calculated as follows:

[0075] E=E 烧结 +E 燃料 +E 电力 +E 逸散

[0076] Among them, E represents the total carbon emissions.

[0077] Alternatively, the total amount of carbon emissions generated during the battery production process can be used to obtain the company's annual carbon emission quota, thereby determining the company's carbon assets. Corporate carbon assets are of great significance to the management and optimization of enterprises. First, based on the company's carbon assets, compliance management and risk management can be carried out on the company to ensure that the company's carbon emissions comply with regulations. At the same time, future emission needs and quota gaps can be predicted based on carbon assets. Secondly, the company's carbon assets can also promote the company's green transformation. Through carbon assets, companies are prompted to examine their carbon emission sources and emission reduction potential, thereby promoting companies to adopt more environmentally friendly and low-carbon production methods and motivating companies to make decisions that are conducive to green development. Finally, based on the company's carbon assets, strategic planning and decision-making support can be provided to the company, that is, based on the company's carbon assets, emission reduction targets can be formulated, strategies for investing in low-carbon technologies and clean energy can be developed, and the company's ability to adapt to climate change can be evaluated.

[0078] Optionally, early warning parameters can be preset according to the carbon emission quota of the enterprise, and an early warning will be issued when the total real-time carbon emissions of the enterprise exceed the early warning parameters. By establishing an early warning mechanism for corporate carbon emissions, enterprises can detect their own carbon emissions in real time, promptly identify the risk of emissions approaching or exceeding the quota, and take timely response measures. At the same time, it can encourage enterprises to pay more attention to carbon emission management and promote enterprises to actively implement energy-saving and emission reduction measures, such as improving production processes, adopting clean energy, and improving energy efficiency, so as to avoid early warnings and the potential risks that come with them, which will help enterprises reduce their carbon footprint and reduce energy costs.

[0079] Through the above step S102, based on the equipment information of the environmental control equipment used in the battery production process, the fugitive emissions of the gas emitted by the environmental control equipment are determined; step S104, the production emissions in the battery production process are obtained; step S106, based on the fugitive emissions and the production emissions, the total carbon emissions in the battery production process are determined. The purpose of obtaining the total carbon emissions according to the carbon emissions generated by the fugitive emissions and the production emissions can be achieved, and the technical effect of improving the accuracy of the calculation results of the carbon emissions in the production process of the positive electrode materials of lithium batteries is achieved, thereby solving the technical problem of the unsatisfactory accuracy of the calculation results of the carbon emissions in the production process of the positive electrode materials of lithium batteries in the related art.

[0080] Based on the above embodiments and optional embodiments, the present application proposes an optional implementation mode: Figure 2 It is a schematic diagram of an optional method for determining carbon emissions in a battery production process provided in an embodiment of the present application. As a new type of energy, lithium batteries have the advantages of high energy density, long cycle life, renewable materials and a wide operating temperature range, and are considered to be an important choice to replace traditional energy sources. However, greenhouse gases and waste are generated during the production and use of lithium batteries, which puts certain pressure on the environment. At present, the core requirements for lithium battery production include hazardous substance control, carbon footprint requirements, recycling requirements and digital battery passports. In order to meet the above requirements, all companies in the battery value chain need to strive to achieve carbon neutrality.

[0081] The carbon emissions of lithium battery positive electrode materials account for a high proportion of the overall carbon emissions of lithium batteries. In order to reduce the total carbon emissions of lithium batteries and meet the carbon footprint requirements of lithium batteries, it is necessary to verify the carbon emissions status of lithium battery positive electrode material manufacturers and establish a carbon asset management system. Figure 2 The method shown is used to calculate the carbon emissions during the production of lithium battery positive electrode materials.

[0082] like Figure 2 As shown, the steps of the method for calculating carbon emissions in the production process of lithium battery positive electrode materials are as follows: S1. Obtain emission data in the production process of lithium battery positive electrode materials; S2. Divide emissions into different types according to energy or material consumption: sintering emissions, combustion emissions, electricity emissions and fugitive emissions; S3. Separately calculate sintering emissions, combustion emissions (i.e. fossil fuel emissions), electricity emissions (sintering emissions, combustion emissions, and electricity emissions together constitute production emissions) and fugitive emissions (i.e. fugitive emissions); S4. Calculate the carbon emissions in the production process of lithium battery positive electrode materials.

[0083] Step S1, obtaining emission data during the production process of lithium battery positive electrode materials;

[0084] Obtain emission data during the production of positive electrode materials for lithium batteries, including the consumption of lithium salts during the sintering of positive electrode materials (i.e., the raw material consumption of lithium salt raw materials), the reaction rate of lithium salt sintered samples (i.e., the sintering reaction rate), and the mass fraction of carbon dioxide produced by the lithium salt sintering reaction, the fossil fuel consumption of the enterprise (i.e., the fossil fuel consumption), and the net electricity purchased by the enterprise (i.e., the electricity consumption);

[0085] Step S2, classifying emissions into different types according to energy or material consumption: sintering emissions, combustion emissions, power emissions and fugitive emissions;

[0086] The above-mentioned sintering emissions are direct emissions of carbon dioxide generated in the sintering process of lithium battery positive electrode materials; the above-mentioned combustion emissions are direct emissions of carbon dioxide, methane and nitrous oxide generated in the combustion process of fossil fuels; the above-mentioned electricity emissions are indirect emissions generated by the use of purchased electricity; the above-mentioned fugitive emissions are emissions generated by environmental control equipment, including refrigerant fugitive emissions of refrigeration equipment and direct emissions generated by the fugitive emissions of carbon dioxide, heptafluoropropane, etc. from fire extinguishers (i.e. fire extinguishing equipment);

[0087] Step S3, respectively calculating sintering emissions, combustion emissions (i.e. fossil fuel emissions), electricity emissions (sintering emissions, combustion emissions, and electricity emissions together constitute production emissions) and fugitive emissions (i.e. fugitive emissions);

[0088] Step S4, calculating the carbon emissions during the production process of lithium battery positive electrode materials.

[0089] The calculation formula for sintering emissions is as follows:

[0090] E 烧结 =∑ p ∑ q AD 锂盐p,q ×η p,q ×F p,q

[0091] Among them, E 烧结 Indicates the sintering emissions generated during the sintering process, in tCO2; AD 锂盐p,q represents the consumption of the pth batch of lithium salt raw material q (i.e. raw material consumption), in units of t (tons); η p,q represents the sintering completion rate of the pth batch of lithium salt raw material q. The sintering reaction rate of the lithium salt raw material can be determined by electrochemical analysis or thermogravimetric analysis; F p,q It represents the relative mass fraction of carbon dioxide produced by the sintering chemical reaction of the pth batch of lithium salt raw material q. For example, the relative mass fraction of carbon dioxide produced by the sintering chemical reaction of lithium carbonate is 44 / 74.

[0092] Fossil fuel emissions are calculated as follows:

[0093] E 燃烧 =E 二氧化碳 +E 甲烷 +E 氧化亚氮

[0094] Among them, E 燃烧 Represents fossil fuel emissions from fossil fuel combustion, in tCO2e (tons of carbon dioxide equivalent); E 二氧化碳 It represents the direct carbon dioxide emissions from the combustion of fossil fuels, in tCO2e; E 甲烷 It represents the direct methane emissions from fossil fuel combustion, in tCO2e; E 氧化亚氮 It represents the direct nitrous oxide emissions from fossil fuel combustion, in tCO2e.

[0095] The formula for calculating direct carbon dioxide emissions from fossil fuel combustion is as follows:

[0097] Among them, AD 燃料 Indicates the amount of fossil fuels (i.e. fossil fuel consumption), in tons; EF 二氧化碳 Indicates the emission factor of carbon dioxide produced by the combustion of fossil fuels (i.e. the second emission factor corresponding to carbon dioxide), the unit is tCO2 / t (tons of carbon dioxide / ton); GWP 二氧化碳 represents the global warming potential of carbon dioxide; n represents the type of fossil fuel.

[0098] The calculation formula for the emission factor of carbon dioxide (i.e. the second emission factor corresponding to carbon dioxide) is as follows:

[0099]

[0100] Among them, CC i,j represents the carbon content of fossil fuel j in facility i; OF i,j represents the carbon oxidation rate of the combustion of fossil fuel j in facility i; It expresses the ratio of the relative molecular mass of carbon dioxide to carbon.

[0101] The formula for calculating direct methane emissions from fossil fuel combustion is as follows:

[0102] E 甲烷 =∑ n AD 燃料 ×EF 甲烷 ×GWP 甲烷

[0103] Among them, EF 甲烷 It represents the emission factor of methane produced by the combustion of fossil fuels (i.e. the second emission factor corresponding to methane), with the unit of tCH4 / t (tons of methane / ton); GWP 甲烷 represents the global warming potential of methane; n represents the type of fossil fuel.

[0104] The direct nitrous oxide emissions from fossil fuel combustion are calculated as follows:

[0105] E 氧化亚氮 =∑ n AD 燃料 ×EF 氧化亚氮 ×GWP 氧化亚氮

[0106] Among them, EF 氧化亚氮 It represents the emission factor of nitrous oxide produced by the combustion of fossil fuels (i.e. the second emission factor corresponding to nitrous oxide), with the unit of tN2O / t (tons of nitrous oxide / ton); GWP 氧化亚氮 represents the global warming potential of nitrous oxide; n represents the type of fossil fuel.

[0107] Fossil fuel combustion is generally not the main emission source for lithium battery positive electrode material manufacturers. Companies can choose appropriate methods to detect the carbon content of fossil fuels based on their own testing capabilities and conditions. For example, professional institutions regularly test the carbon content of fossil fuels. Table 1 shows the default values ​​of carbon emission factors for fossil fuel combustion. The carbon content, carbon oxidation rate, and methane and nitrous oxide emissions of fossil fuels can refer to the default values ​​in Table 1.

[0108] Table 1 Default values ​​of carbon emission factors for fossil fuel combustion

[0109]

[0110] The calculation formula for electricity emissions is as follows:

[0111] E 电力 =AD 电力 ×EF 电力

[0112] Among them, E 电力 Indicates the carbon emissions generated by purchased electricity, in tCO2; AD 电力 Indicates the amount of electricity purchased (i.e. electricity consumption), in MWh (megawatt-hours); EF 电力 It represents the average emission factor of the regional power grid (i.e. the third emission factor), with the unit of tCO2 / MWh (tons of carbon dioxide / megawatt hour).

[0113] Table 2 shows the default values ​​of the average carbon dioxide emission factors for electricity. The average carbon dioxide emission factors for electricity in some regions are shown in Table 2.

[0115]

[0116] The formula for calculating fugitive emissions from environmental control equipment is as follows:

[0117] E 逸散 =∑ k [(Num k ×EF 逸散，k )×GWP k ]

[0118] Among them, E 逸散 Indicates the fugitive emissions of environmental control equipment, in tCO2e (tons of carbon dioxide equivalent); Num k Indicates the number of equipment type k; EF 逸散，k represents the greenhouse gas fugitive emission factor (i.e. the first emission factor) of equipment type k; GWP k Represents the global warming trend of greenhouse gases for device type k.

[0124] The total amount of carbon emissions generated by the battery production process can be used to obtain the company's annual carbon emission quota, and then determine the company's carbon assets and establish a carbon asset management system. Corporate carbon assets are of great significance to the management and optimization of enterprises. First, based on the company's carbon assets, compliance management and risk management can be carried out on the company to ensure that the company's carbon emissions meet regulations. At the same time, future emission needs and quota gaps can be predicted based on carbon assets. Secondly, the company's carbon assets can also promote the company's green transformation. Through carbon assets, companies are prompted to examine their carbon emission sources and emission reduction potential, thereby promoting companies to adopt more environmentally friendly and low-carbon production methods and motivating companies to make decisions that are conducive to green development. Finally, based on the company's carbon assets, strategic planning and decision-making support can be provided to the company, that is, based on the company's carbon assets, emission reduction targets can be set, strategies for investing in low-carbon technologies and clean energy can be developed, and the company's ability to adapt to climate change can be evaluated.

[0125] Early warning parameters can be preset according to the carbon emission quota of the enterprise. When the total carbon emission of the enterprise exceeds the early warning parameters, an early warning will be issued. By establishing an early warning mechanism for enterprise carbon emissions, enterprises can detect their own carbon emissions in real time, promptly identify the risk of emissions approaching or exceeding the quota, and take timely response measures. At the same time, it can encourage enterprises to pay more attention to carbon emission management and promote enterprises to actively implement energy-saving and emission reduction measures, such as improving production processes, adopting clean energy, and improving energy efficiency, so as to avoid early warnings and the potential risks that come with them, which will help enterprises reduce their carbon footprint, reduce energy costs, and improve economic efficiency and competitiveness.

[0126] Through the above steps, the carbon emissions in the production process of lithium battery positive electrode materials can be accurately calculated, avoiding the deviation caused by the use of literature values ​​or empirical values ​​of positive electrode materials, and providing technical support for energy conservation and carbon reduction in the production process of lithium battery positive electrode materials.

[0127] The above optional implementation method achieves at least the following effects: by classifying carbon emissions according to their sources and calculating the carbon emissions from different sources in different ways, the total carbon emissions in the production process of lithium battery positive electrode materials can be determined, thereby avoiding the inaccuracy caused by using literature values ​​or empirical values ​​and ensuring the accuracy of the total carbon emissions; carbon assets are determined based on the total carbon emissions and carbon emission quotas, and the compliance of battery production can be ensured through the planning and management of carbon assets, and corresponding strategic planning and decision-making support can be formulated based on carbon assets to improve management efficiency.
