The 'Evaluation Requirements for Green Factory of Power Lithium-ion Battery Manufacturing Industry' (T/CESA 1080-2020) stipulates the principles, methods, index systems and requirements, procedures and reports for the evaluation of green factories in power lithium-ion battery manufacturing industry. The evaluation of factories for power lithium-ion battery products, and the evaluation of green factories that produce other types of lithium-ion battery products can be implemented by reference.

Power lithium-ion batteries are batteries that use lithium ions as conductive ions, move between anode and cathode, and realize charging and discharging through mutual conversion of chemical energy and electrical energy, thereby providing energy for the power system of electric vehicles. They are widely used in new energy vehicles. 'Requirements for Green Factory Evaluation of Power Lithium-ion Battery Manufacturing Industry' (T/CESA 1080-2020) (hereinafter referred to as 'this standard') stipulates the principles, methods, index systems, requirements and procedures for the evaluation of green factories in power lithium-ion battery manufacturing industry And reports, etc., are applicable to the evaluation of factories producing power lithium-ion battery products, and the evaluation of green factories that produce other types of lithium-ion battery products can be implemented by reference.

This standard revolves around the basic requirements specified in the 'Green Factory Evaluation Guidelines' (GB/T 36132) and 'Electronic Information Manufacturing Green Factory Evaluation Guidelines' (SJ/T 11744), as well as infrastructure, management system, energy resource input, Six first-level indicators including product, environmental emissions, and performance have been developed, taking full account of the characteristics of the power lithium-ion battery product manufacturing industry, and further refined 29 second-level indicators, involving 101 specific requirements. For example, the responsibility should be fulfilled in accordance with the relevant national regulations on the management of the recycling and utilization of power batteries for new energy vehicles; it is advisable to calculate the recyclable rate of its products, and use the calculation results to improve the recyclable rate of the product; it is appropriate to assume the extended responsibility of the producer , On its own or in cooperation with comprehensive utilization companies, under the premise of ensuring safety and controllability, and in accordance with the principle of first cascading utilization and then recycling, carry out multi-level and multi-purpose rational utilization of waste power batteries to reduce comprehensive energy consumption and improve energy utilization efficiency. Improve the level of comprehensive utilization and economic benefits, and ensure the environmental protection of unusable residues; should coordinate with automobile manufacturers to code the produced power batteries in accordance with the requirements of the 'Automotive Power Battery Coding Rules' (GB/T 34014); Cooperate with automobile manufacturers to upload power battery codes and new energy vehicle related information through the traceability information system in time.

In order to ensure the operability of the evaluation work, this standard refines and classifies the five green factory performance indicators 'intensification of land use, harmless raw materials, clean production, waste recycling, and low-carbon energy', and classifies power lithium-ion batteries The green performance level of the product manufacturing plant is divided into 3 levels, and the indicator requirements and evaluation scores corresponding to different performance levels are given. For example, it is clear that the 'total cobalt production per unit product' index requirements for the 'clean production' of the power lithium-ion battery manufacturing industry are ≤250g/104Ah (level 1), ≤300g/104Ah (level 2), ≤350g/104Ah (Level 3); The index requirements of 'NMP (N-methylpyrrolidone) recovery rate' corresponding to 'waste recycling' are ≥97% (level 1), ≥95% (level 2), ≥90% (level 3) ); The index requirements of the 'comprehensive energy consumption per unit product' corresponding to 'energy low carbon' are ≤0.35tce/104Ah (level 1), ≤0.4tce/104Ah (level 2), ≤0.6tce/104Ah (level 3), etc. .
