In recent years, the rapid development of my country's new energy automotive industry has driven the rapid rise in power lithium-ion battery, affected by service life (generally 5 to 8 years), 2018 is considered to be a dynamic lithium-ion battery newspaper in the first year, related motivation The construction of a lithium-ion battery recovery system is also imminent. From 2012 to 2018, many departments such as the State Council, the Ministry of Industry and Information Technology, the Development and Reform Commission have announced 9 policy documents such as "New Energy Automobile Waste Body Comprehensive Utilization Industry" "Provisional Regulations on the Administration of New Energy Automobile Power Battery Recycling and Utilization." Promote the construction of dynamic lithium-ion battery recycling system.

Policy encourages battery production company and comprehensive utilization company to cooperate, under the premise of ensuring safety, according to the principle of renewable use of the first lattice, the use of multi-level, multi-purpose reasonable utilization, reduce comprehensive energy consumption, and improve energy utilization Efficiency, enhance the level of comprehensive utilization and economic benefits, and guarantee environmental protection disposal of the residue. The five major links use control battery recycling as the pioneer of new forces, and Weima cars have shared their associated experience and planning to the industry by depth in the industry through the public class. According to Zhang Jian, the recycling engineer of Weima Automobile Power Lithium Ion Battery, Weima battery recycling system is important by the R & D link, production link, sales link, recycling link, traceable five sectors: 1.

Important by the R & D links from Pack, Products Data, three parts of the battery recovery operation department, important responsibilities are compliance with the design and development principles, strictly implement Weima's technical parameters required for battery products (including deformation grade, scrap conditions, etc.), test phase dynamic battery pack management, power lithium ions Corporate code specification, scrap battery assessment, etc.; Composed by pre-sale, important responsibility for power lithium-ion battery recycling service outlet standard / construction, dynamic lithium-ion battery repair / replacement, distributor dynamic lithium-ion battery temporary storage, scrapped work; 4, the recycling link is responsible for the battery recycling operation department The important task is to use / regenerate utilization, waste dynamic lithium-ion battery management, waste-free, lithium-ion battery management, waste-free, and the source of the source is controlled by the Quality Center, responsible for the source of lithium-ion batteries of each link.

Management, traceability management platform construction and management. In addition, according to the "Interim Provisions on the Administration of New Energy Automobile Power Battery Recycling", the automobile production company should upload the recycling service outlet information in the traceability management platform, the first batch of Weima cars (total 26) Recycling service outlets have been Completed, and included in the construction of recycling system, it became the first batch of car companies for recycling service outlets in the country. Recycling uses gravity focusing on the ladder use according to the principle of policies, according to the principle of light scrap battery, battery performance drops to 30% to 80% of the original performance, generally recommended gradient utilization, by screening, dismantling, reorganization The upper label is used to use the label, which can be used in the field of energy storage systems, street lights, UPS power supplies, low-speed electric vehicles.

Related to severe scrap batteries, battery performance drops below 30% of the original performance, generally adopt regenerative utilization, by dismantling regeneration, by chemical methods, electrode materials, especially cobalt (CO), nickel (Ni) , Lithium (Li) and other precious metals. However, from the current situation, the way the power lithium-ion battery scrap treatment is still based on dismantling recycling. Related data shows that in 2017, the national ladder uses and disassembles the scrapped lithium-ion battery (including digital lithium ion batteries), of which the battery is disassembled for 95%.

The reason why the ladder use is relatively small includes: 1. Battery vendors are reluctant to take on battery safety risks, and do not want the scrap battery to flow again into the market; 2. The past dynamic lithium-ion battery newspapers have less waste, and the old battery matches is relatively difficult; 3.

At present, the dynamic lithium-ion battery ladder is not mature, and the technical accumulation is continuously carried out. The energy storage market, reuse the market space has not released large-scale release. However, in order to give full play to the residual value of the retired dynamic lithium-ion battery, Weima cars still focus on the trails of the power lithium-ion battery.

It is understood that the recycling path of Weima dynamic lithium-ion batteries is the whole package and module: the whole package is generally used in the energy storage system, the module is generally used in the energy storage system, tricycle, two-wheeled car, low speed quadrowat. However, no matter which recycling path must comply with the technical specifications of the ladder, the technical specification is important to include five aspects, which are basic information collection, appearance inspection, performance testing, communication calibration, product requirements. In the whole package, Weizhi uses the current energy storage product, using the ladder battery development microcarns, combined with the photovoltaic and power grid, will build Weima Auto Characteristic power storage project, speeding up the product commercialization.

The process of module applications involves pretreatment, PACK disassembly specifications, PACK dismantling processes, and practical applications. Waste batteries should be preprocessing before dismantling, including information collection, security checking, etc., in Pack dismantling specification, Weima is based on the design characteristics of the WM battery pack and the national dismantling specification, and formulates a system for different mileage.

Use the dismantling specification and dismantling process steps to clarify the requirements of personnel, equipment, venue, etc. in the dismantling process. On the basis of ladder utilization, Weima cars also constructs three levels of power-based dynamic lithium-ion battery recycling by recycling systems and recycling paths, and three from the system establishment, construction and full life cycle.

In terms of scientific management of recycling system for retired dynamic lithium-ion batteries. Previously, Weima has signed a strategic cooperation agreement with my country Tower. In terms of the use and recycling of the dynamic lithium-ion battery, enhance the market-based recycling model of resource environment, comprehensively and effectively perform the battery life cycle traceability management.
