Recently, Xin Guobin, deputy director of the Ministry of Industry and Information Technology, pointed out that the method of recycling the powerful lithium-ion battery will be announced as soon as possible. According to the data released by my country's Automotive Industry Association, in 2017, my country's new energy vehicle sales was 700,000. Here, my country's new energy vehicle has reached around 1.

6 million vehicles, and a large part is pure electric car. Behind this is more and more power lithium-ion batteries enter the scrap recycling link. There is a research expectation to reach 32.

2GWH in my country's electric vehicle power lithium-ion battery year to 2020. According to the vehicle scrap and market actual operation, the 2018 movement of the lithium-ion battery will be increased. However, do these power lithium-ion batteries entering the scrap recovery link really can achieve a ladder according to the idea? Is it ready to be prepared by the recovery dismantling of the power lithium-ion battery? At present, there is still no exact answer to this series of questions.

The ladder use is subject to the battery performance ladder. It has always been an ideal place for the power lithium-ion battery to be completed as a vehicle supply kinetic energy. Whether it is from the perspective of green development, it is still from the perspective of economic operation.

However, the actual situation is not ideal. "The dynamic lithium-ion battery that is in the scrapping link is from the earliest new energy car, but the early battery performance is very poor, it is difficult to meet the requirements of the ladder. "Deputy General Manager of Beijing Saidimei Resources Resection Research Institute Co.

, Ltd. pointed out that although everyone wanted to eliminate the battery to the energy storage, it is the driving force of the scrap recovery link. Lithium-ion batteries are difficult as everyone is willing.

This is also a new energy vehicle that is "ten cities and thousands" stage demonstrations are all in idle states, and it cannot be used to use one of the territories. Because this batch of vehicle battery performance is not up to standard, it is difficult to achieve a ladder. It is difficult to achieve a ladder, and where is these batteries? The reporter learned that due to the research experimental needs due to car enterprises, power lithium-ion battery companies, research institutions have research experiments, many of the power lithium-ion batteries to be scrapped are used by these companies for experimental research, and the pen flows into the scrap disassembly company.

In addition, the reporter's investigation also discovered that due to the less consideration of the recycling, there was no easy dismantling method in the dynamic lithium-ion battery design link, which added battery pack dismantling. In the ladder, since the battery pack is composed of many monomers, it is also a quite time, and the work of the financial lithium-ion battery is newly used. Some waste battery recycling agencies even for some non-disashability battery packs "thank you unintended".

Zhang Ying, secretary general of my country's Renewable Resources Recycling Association, said that the test technology of waste batteries is not mature enough, the remaining life and battery status cannot be evaluated, which leads to recycling economic big discount. The battery recycling is the development of the dynamic lithium-ion battery scrap recovery industry in the future. The overall scale of the annual lithium-ion battery recovery will reach 15.

6 billion yuan. By 2023, the amount of scrap will reach 101GWH, about 1.16 million tons.

According to the development of new energy vehicles, the dynamic lithium-ion battery or the first batch of retired tides in 2018 will be rapidly increased in the future. It is to see such a prospect, although there are still a lot of problems in the dynamic lithium-ion battery recovery market, still attracting a lot of capital to join, plus, such as Guo Jie said that the Ministry of Environmental Protection has been clear, the recycling of the dynamic lithium-ion battery Disassembly companies do not have special qualifications, that is, this industry is open to all companies. Because there is no qualification threshold, many capital has been involved in this field.

However, opportunities do not mean a sails, although the power lithium-ion battery recovery industry does not have special requirements for the company's qualifications, but because of the maintenance industry, new companies should be very difficult. For example, an employee who is unwilling to disclose is told reporters that the leaders of Beijing New Energy Administration Department have clearly stated that the scrap collection and dismantling mechanism of the power lithium-ion battery will not be established in Beijing. Guo Jie also said that in Beijing's related plans, the power lithium-ion battery eliminated by Beijing New Energy Automobile will be used for energy storage, not to report the dismantling solution, but due to poor performance, the ladder utilization Not high.

It is understood that this dynasty dynamic lithium-ion battery scrap recovery industry has used wet metallurgy process to solve dynamic lithium-ion batteries, but because this process is from the heavy pollution chemical industry, it is difficult to be very high in the requirements of Beijing, Tianjin, etc. Local acceptance. The power lithium-ion battery group belongs to the ninth type of dangerous goods.

It should meet the relevant regulations of dangerous goods transport according to the relevant regulations, and the cost has increased in invisible, which exacerbates the difficulty of recycling of the power lithium-ion battery pack. At the same time, although the recycling of power lithium-ion batteries should not be particularly qualified, because the power lithium-ion battery belongs to hazardous waste, the company wants to scrap disassemble and reuse, there must be dangerous waste recycling license, this license The acquisition of qualifications is not easy, and there is a strict requirement in technology, equipment and environmental assessment. Guo Jie analyzed, Beijing Saidimei Resources Re-use Research Institute Co.

, Ltd. is trying to solve the dynamic lithium-ion battery with physical approach, and dismantle the waste battery pack to the original material, and then recover, because this method does not involve Chemical solution, so I can get the EIA license. However, Guo Jie also said that it is necessary to build a process line of approximately 3,000 tons of re-recovery capacity, with a fund investment of 30 million yuan.

In addition, there is also a suspicion that the insiders refer to the pure physical method recovery to dismantle the dynamic lithium-ion battery. It is believed that it is difficult to completely separate the various chemical materials that have been mixed together without chemistry. The recovery rate of the full-industrial chain is non-proportional promoting the recycling rate of the dynamic lithium-ion battery can be improved.

It is not necessary to recover the process of decolizing the decomposition. As a powerful lithium-ion battery recycling company staff said: "If a battery pack is not disassembled when designing, it is difficult to dismantle the battery pack when entering the recycling link. Reuse, even if you can dismantle, there will be a lot of steps, and the time consuming.

"Guo Jie also said that although" Interim Method "(hereinafter referred to as" Interim Method ") is expected to implement this year, the previously processed battery pack is not included in the" Interim Method " Management, traceability, the detachable decomposition of the battery pack is also very difficult, and this part of the solution of the waste battery is still very difficult. As the drafting unit of "Interim Method", my country's Automobile Technology Research Center (hereinafter referred to as "Sports Center") said that the scrap disassembly dismantling of the dynamic lithium-ion battery is non-enhanced source control, and implemented the processed responsibility extension system, let the car Processing company undertakes the main responsibility of dynamic lithium-ion battery recovery, battery processing company guarantees the effective use of dynamic lithium-ion batteries and environmental protection solutions, and this is the basic principle of "Interim Method". Li Zhenqi, an engineer engineer, an engineer, an engineer, said that the scrapping recovery of dynamic lithium-ion batteries will adhere to the product full-life cycle concept, to play the market use, the core measures of "Interim Method" are coding and traceability management, establish a unified power lithium Ion battery product coding standard, traceable information management system and related information sharing mechanism; ensure that power lithium-ion battery products can be checked, go to the chasing, node controllable.

Zhang Ying also said that the "Interim Method" clarifies that the dynamic lithium-ion battery design, access, processing, sales, maintenance is replaced to the scrapped and regenerative utilization, and put forward the punishment mechanism, such as can smoothly, strict implementation will advance Regular ordered development of dynamic lithium-ion battery recycling. "But there is still very uncertainty in supervision and market operation standards. Zhang Ying said.
