　　Author ：Iflowpower – Portable Power Station Supplier

As one of the world's largest electric vehicle market, my country has ushered in the first dynamic lithium battery training period this year. On a public class held on Wednesday (December 26), Weima has given the above judgment. This emerging car manufacturer said that the waste-powered lithium battery is challenged in the environment and social resources.

If the disposed is not properly disposed, the latter not only has huge environmental and safety hazards, but also cause waste of resources. Therefore, the recycling of the power lithium battery is of great significance in the economic, environment, industry, and corporate level. Wei Ma Car Power Lithium Battery Recycling Engineer Zhang Jian.

In the above, Weima Automobile has combed the world's governments in the technical path and policy system of the dynamic lithium battery recovery. From the form of form, the dynamic lithium battery recovery and renewal is two kinds of ladder utilization and regeneration. For mild scrap batteries, the battery performance drops to 30% -80% of the original performance, generally recommended gradient utilization, by screening, disassembly, reorganization, labeled labels, can be used for energy storage systems, streetlights, UPS Power, low-speed electric vehicle and other fields.

With regard to severe scrap batteries, battery performance is below 30% of the original performance, generally use regenerative utilization, by dismantling regeneration, by chemical methods, the electrode material, especially cobalt, nickel, lithium, etc. In the policy system level, the current dynamic lithium battery recycling of developed countries is mainly market regulation, and the government constraint is supplemented. For example, in Germany, the government legislation is recycled, producers undertake important responsibility, and set up fund to improve the market construction of recycling system.

Japan's production method of dynamic lithium batteries is gradually transformed into cyclic reuse mode, and the company is involved in battery recycling as a pioneer. The United States is mainly market regulation, and the government has a constrained management by developing environmental protection standards, assisting the recycling of waste power lithium batteries. In my country, from 2012 to 2018, there were several departments of the State Council, the Ministry of Industry and Information, and the National Development and Reform Commission.

Norms of New Energy Automobile Waste Battery Comprehensive Utilization Industry Standards Conditions "" New Energy Automobile Power Battery Recycling Traces Management Management Organization " , Promote the construction of power lithium battery recycling system. Encourage battery production company and comprehensive utilization company to cooperate, under the premise of safety and control, in accordance with the principle of renewable use of the first lattice, the use of multi-purpose, multi-purpose reasonable utilization, reduce comprehensive energy consumption, and improve energy utilization efficiency Improve comprehensive utilization levels and economic benefits, and ensure environmental protection disposal that cannot be used. Within a global scale, the pilot and research on the dynamic lithium battery ladder is being carried out.

Take the US Electric Vehicle Manufacturer Tesla, which announced the company's Lithium-ion battery energy storage system Powerwall and PowerPack in 2015, and announced the solar roof in 2016. Such attempts can be considered a typical case-utilization. In fact, it is also an in the eyes of the Weima car that is a smart electric vehicle popularity.

Zhang Jian said that in order to make the retired power lithium battery more fully utilized, Weima will operate from battery recycling system, power lithium battery recycling system construction, dynamic lithium battery full life cycle traceability, three aspects, comprehensive management, implementation Reasonable use of the residual value of retired dynamic lithium batteries, with a view to protecting the environment, while reducing security risks, maximizing the company's cost and benefits. Weima battery recycling system is important from R & D links, production links, sales links, recycling links, and traceable five sectors. The research and development link is important from the three parts of Pack, product data, and battery recovery operations.

The scope of responsibility is to comply with the design and development principles, strictly implement Weima's technical parameters for battery products (including deformation grade, scrap conditions, etc.), test phase motivation Savory, battery pack management, power lithium battery code specification, scrap battery assessment and other related work. The production process is important by the two parts of the vehicle, and the ME is responsible for the production of dynamic lithium battery warehouse planning, scrap transfer, and dynamic lithium battery production.

The sales link consists of pre-sales, important responsibility for power lithium battery recycling service outlets / construction, dynamic lithium battery repair / replacement, distributor power lithium battery temporary, scrapped work. The recycling link is responsible by the battery recovery operation department. The important task is to use the main use / regeneration utilization, waste dynamic lithium battery management, waste dynamic lithium battery recycling system construction.

Traceability is controlled by the Quality Center, responsible for the management of the source of the power lithium battery, the construction and management of the source management platform. In addition, the Weima Automobile Battery Traces Upload System has also been completed, realizing the national platform coordinating docking and has been put into use, and the traceability of the information of the power lithium battery. According to the "Interim Provisions on the Management of New Energy Automobile Power Battery Recycling and Utilization", automobile production companies should upload recycled service outlets in the traceability management platform.

Weima Automobile is a batch of car companies for recycling service outlets. The first batch (total 26) Recycling service outlet information declaration has been completed, and is included in the construction of recycling system. At present, the recycling practice of Weima dynamic lithium battery is important for the ladder.

Retired batteries can be used as energy storage applications in microgrid, distributed energy system scenarios, or on two wheels, three rounds, four-wheeled vehicles. When the retired battery can no longer be applied in the above two ways, it is the disposal of the resource regeneration company. The overall idea of ​​recycling is the residual value of crushing battery, and the path is a whole package and module.

Zhang Jian said that no matter which recycling path, we must comply with the technical specifications of the Weima ladder. This set of technical specifications are important to include five aspects, which are basic information acquisition, appearance inspection, performance testing, communication calibration, product requirements. Among the recycling path of Wei Ma power lithium battery, the whole package is generally used in the energy storage system, the product features are easy to obtain, reduce selection, restructuring cost, easy maintenance, replacement.

The module is generally used in the energy storage system, tricycle, two-wheeled, low-speed quadrowtle, its product characteristics are: product technical parameters standardization, ladder products of different voltage platforms, same brand module selection, single differences High energy density, light weight. Whole package uses China Weizhi according to the characteristics of the current energy storage product, using the ladder battery development microcarns, combined with the photovoltaic, grid, will build Weima car special power energy storage project, speed up the promotion of product commercialization. The process of module applications involves pretreatment, PACK disassembly specifications, PACK dismantling processes, and practical applications.

In addition, waste batteries must be preprocessed before dismantling, including information collection, security check, etc. At the PACK dismantling specification, Weima is based on the design characteristics of the WM battery pack, and formulates the customization of dismantling specifications and dismantling process for different mileage packages, and clarifies the personnel in the dismantling process. Equipment, venue, etc.

Participation experts believe that in 2020, new energy subsidies will be completely resurrected, and all power lithium batteries should consider mileage, safety, price and other comprehensive factors, and cannot continue to impose the constant meaning of endless mileage. Battery and vehicle company's technical capabilities will face major challenges. Yang Yusheng, academician Yang Yusheng, said that the over-pursuit of endurance will cause the battery installation density, not only easy to reduce safety, leading to the fire, and will also increase the weight of the car, and the original intention of energy saving and emission reduction.

Battery 100 people will be directed by the Qingjiao, 95% of consumers' mileage between 30 kilometers and 100 kilometers, too long, will only make battery costs, and the price of new energy vehicles has soared. This is meaningless to consumers. Therefore, after the end of the national subsidy, how to weigh the company in technology routes, choose, worthwhile.

Yang Yusheng pointed out a technical route reunitely electric vehicle binding to lithium iron phosphate ion battery. He believes that this is one of the paths of solving the path of current mileage and security costs, which is also convenient to advance marketization. In terms of lithium iron phosphate ion batteries, major domestic battery companies have research, including Guoxuan Haoke, held this conference.

The General Assembly also issued this scientific and technological achievement special prize to the R & D and industrialization projects of the 190WH / kg lithium iron phosphate ion battery. At the same time, the 190Wh / kg lithium iron phosphate ion battery also mounted on the 40th anniversary of the celebration of Anhui Province, the 40th Anniversary Exhibition. .
