At present, my country has become the forefront of New Energy Automobile production and sales, with the return of new energy vehicle power storage batteries, its recycling is a pressing problem. How to achieve recycling of retired power storage battery? How to prevent pollution during the recovery? Start implementation, which means that Shenzhen has become the first city in the country to develop a new energy vehicle power lithium-ion battery recycling system construction method. According to statistics from my country Automotive Industry Association, from 1 to May this year, my country's new energy automotive production and sales have completed 328,000 units, up 122.

9% and 141.6% from the same period of the previous year. The production and sales of power storage batteries will climb year by year, and the construction of recycling system is also imminent.

In February this year, 7 departments of the Ministry of Industry and Information Technology issued the "Interim Measures for the Administration of New Energy Automobile Power Battery Recycling", requiring strengthening the recycling management of new energy vehicle power storage batteries. According to Shenzhen's recovery method, by 2020, to achieve a full life cycle supervision of all new energy vehicles in the subsidy range, establish a complete dynamic lithium-ion battery supervision recovery system. If the battery is dismantled, wastewater, exhaust gas, waste sagging according to Shenzhen traffic police statistics, as of April this year, Shenzhen Xin Energy Automobile has exceeded 170,000 vehicles.

With average of 5-8 years of service life with new energy vehicles, Shenzhen will face the problem of large-scale phase-out of dynamic lithium-ion batteries. Experts measure, after 2018, the new energy vehicle power battery will enter the scale of retirement period, and it is expected that more than 200,000 tons have been accumulated by 2020. If you can use 70% to be used for the ladder, about 60,000 tons of battery needs to be scrapped.

How to do after retiring? Zhejiang Tianneng Power Materials Co., Ltd. Technical leader Queo Bo said, from the dynamic lithium-ion battery retired from the new energy car, with a certain residual value, after choice, test, etc.

, can be applied The field of energy storage is;. According to reports, Shenzhen Watma Battery Co., Ltd.

uses the retired electric vehicle power lithium-ion battery, which has built a 3 MW phosphate ion battery energy storage power station. Waterma Battery Research Institute, Dean Rao Dingyi said that "In the future, we will consider using waste dynamic lithium-ion batteries to mobile supplement, further explore the application of waste dynamic lithium-ion batteries in the energy storage system. "There is a battery that cannot be traded, and it is said that the technical means will extract elements such as nickel, cobalt, manganese, lithium, and realize the" directional circulation "from waste batteries to battery materials.

Zhang Zhe, member of the Electric Automobile R <000000> D team of the Shenzhen Advanced Technology Research Institute, pointed out that if the power lithium-ion battery dismantling recovery is improper, there will be a lot of wastewater, exhaust gas, waste, and the heavy metals have caused pollution, and it is difficult to repair for decades. At present, the overall scale of the recycling industry will establish a full life cycle supervision. "At present, the new energy vehicle power lithium-ion battery recycling industry is not large, this time, Shenzhen introduces method, the green environmental protection, standardization development of the industry, has a very important significance.

Liu Jianchang, chief researcher, Green Traffic Planning and Design Institute, Shenzhen City, said that the current new energy vehicle currently used in public services can realize battery standard recycling, but some small logistics cars, company transport vehicles, etc., due to less recycling outlets, For the difficulty of recycling in different places, many companies will choose to sell old batteries to small workshops, even casually discard. According to the previous Ministry of Industry and Information Technology, the "Interim Measures for the Recycling Management of New Energy Vehicle Power Battery", a principle of recycling is the principle of producers' responsibility extension - "Automotive Production Company undertakes the main responsibility of the power battery recovery, related companies in power Battery recycling and use each link to fulfill the corresponding responsibility ".

This Shenzhen stipulates that new energy automobile production companies sold in Shenzhen should set up not less than 5 main security outlets in the city. The maintenance, replacement and recycling of dynamic lithium-ion batteries are responsible for the maintenance, replacement and recycling of the power, and the old battery recycled should be handed over. Required recycling company.

Regarding the downstream recycling company, Shenzhen, on the one hand, it is required to establish a complete waste-to-use and harmless treatment desk account, encourage the company to build, build, share the recycling channel; on the other hand, improve the battery recovery mechanism, require When selling new energy vehicles, a certain amount recovery funding for the power lithium ion battery, and the company can apply for subsidies according to the procedure after completing the recovery process. Another important aspect of recycling, it is to establish a full life cycle management concept. On May 17, the Ministry of Industry and Information Technology announced the "Interim Provisions on the Administration of Recycling and Utilization of New Energy Automobile Power Battery" (Draft for Comment), requiring new models to perform traceability management from the date of implementation of the new model.

Automobile production companies should upload recycled service outlet information in the traceability management platform, and announce in the company website. Shenzhen's method requires that by the end of 2018, Shenzhen should build a powerful lithium-ion battery information management platform, establish a source of power lithium-ion battery to check, go to the chasing, node controllable traceability mechanism. Code the power lithium ion battery, encoding and the whole vehicle, the owner corresponds.

"After the battery has the coding and traceability mechanism, who is produced, who is used, all clear. Once an illegal battery is found, you can find the responsible person. Liu Jianchang said.

Increase the recycling technical research, and improve the incentive measures reporters learned in the interview that some battery companies have already started the layout of the battery from manufacturing, consumption to the entire circulation link, but the current power battery recovery is also facing many problems. Previously, the Ministry of Industry and Information Technology has pointed out that the recycling of power storage batteries is an emerging field. It is still in its infancy, facing some outstanding problems and difficulties: First, the recycling system has not yet formed.

At present, most power storage batteries have not been retired, and there is no effective cooperation mechanism between automobile production, battery production, comprehensive utilization and other companies. At the same time, in the implementation of the production person's responsibility extension system, it is necessary to further refine the improvement of relevant legal support; the second is that the recycling technical ability is insufficient. At present, the company's technical reserves, power storage battery ecological design, ladder utilization, high-efficiency metal efficient extraction, etc.

Retired power storage battery discharge, storage, and ladder use products, etc.;. Affected by technical and scale, the current market is not high, and the economic is poor.

The relevant fiscal and tax incentives have not been perfect, and the market-based recycling mechanism has not yet been established. It is understood that Zhejiang Tianneng Group is a new energy battery manufacturing company, related to battery, currently forming "manufacturing-recycling-reproduction-manufacturing" green circulation closed-loop industrial chain, annual production of 500,000 tons, while recycling of dynamic lithium-ion battery It just started. Zhang Tiansheng, Chairman of the Board of Directors of Tianneng Group, said from the company's perspective, in the process of recycling of waste batteries, in the face of some problems, such as construction operations are difficult to land, cross-provincial transfer cycle, high logistics and transportation costs.

Zhang Tian has revealed that the current dynamic lithium-ion battery dismantling, recombination and recovery technology are not mature, the next step, to increase key technical research on dismantling, reorganization, test and life prediction of waste dynamic lithium-ion batteries, improve technical maturity and safety. At the same time, improve the automation level and recovery efficiency of battery dismantling, reorganization, recovery technology, so that the powerful lithium ion battery recovery is economically feasible and safe.
