A few days ago, Vice Minister of the Ministry of Industry and Information Technology, Vice Minister of the Ministry of Industry and Information Technology, pointed out that it is necessary to announce the management of powerful lithium battery recycling 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 batteries into the scrap recovery link. Studies are expected that by 2020, my country's electric vehicle power lithium battery annual scrap volume will reach 32.

2GWH. According to the vehicle scrap and market practical operation, the recycling of lithium battery in 2018 will be greatly improved. However, do these power lithium batteries entering the scrap recovery link really can achieve a ladder in accordance with the idea? Is the recycling dismantling of a power lithium battery ready? At present, there is still no exact answer to this series of questions.

The ladder is used to use the battery performance ladder, which has always been the ideal place after the dynamic lithium battery is completed as a vehicle supply kinetic energy. Whether it is from the perspective of green development, it is also from the perspective of economic operation. However, the situation of reality is not ideal.

"Now entering the powerful lithium battery of the scrap session from the first batch of new energy vehicles, but the early battery performance is very poor, it is difficult to meet the requirements of the ladder. "Deputy General Manager, Beijing Saidimei Resources Researcher Co., Ltd.

, pointed out that while interviewing reporters, although everyone wanted to eliminate the battery in the new energy vehicle, it was used for energy storage, but now enters the power of the scrap recovery link. Lithium battery is difficult, if you are willing. This is also a new energy vehicle that is "ten cities thousand" stage demonstration promotion is all in an idle state, one of the important reasons for unable to use.

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 test demand due to the research test, many dynamic lithium batteries to be scrapped by these companies are rarely infused by these companies. In addition, the reporter's investigation also found that due to the less consideration of the recycling, there is no easy dismantling method in the dynamic lithium battery design link, and the difficulty of disassembly of battery pack is added.

In the ladder, since the battery pack is composed of many monomers, it is necessary to detect if each battery monomer can reuse it is also a quite, the work of the financial lithium battery, and some difficulty, some Waste battery recycling institutions even for some unrecoveant battery packs "thank you unmel". Zhang Ying, secretary general of my country's Renewable Resources Recycling Association, said that the detection technology of waste batteries is not mature, the remaining life and battery condition cannot be evaluated, which leads to recycling economy big discount. The battery recycling is the development of the Rubber Recycling Industry in the next few years.

The overall scale of the ion battery recycling market 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 power lithium battery or the first batch of retired tides in 2018 will rise in the next three years. It is to see such a prospect, although there are still a lot of problems in the power lithium 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 power lithium battery The company should not 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 sail, although the power lithium battery recycling industry does not have special requirements for the company's qualifications, but because of the heavy pollution industry, new companies must pass the difficulties through the EIA. 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 there will be no dynamic lithium batteries will not set up a dynamic lithium battery.

Guo Jie also said that in Beijing's related programs, the power lithium battery in Beijing's new energy vehicles eliminated will be used in the energy storage, do not report waste dismantling treatment, but due to poor battery pack performance, the ladder utilization not tall. It is understood that now, the dynamic lithium battery scrap recovery industry has multi-wet metallurgical process to handle power lithium batteries, but because this process comes from the heavy pollution chemical industry, it is difficult to accept very high in the provision of environmental assessment in Beijing, Tianjin. The dynamic lithium battery pack belongs to the ninth dangerous goods, according to the relevant provisions, its transport should meet the relevant regulations of dangerous goods transportation, invisible new cost, which exacerbates the difficulty of recycling of the power lithium battery pack.

At the same time, although the recovery of the power lithium battery should not be special qualifications, but because the power lithium battery is a hazardous waste, the company wants to scrap disassemble and reuse, there must be dangerous waste recycling licenses, this license qualification It is not easy to make strict requirements in technology, equipment and environmental reviews. Guo Jie introduced that Beijing Saidimei Resources Re-use Research Institute Co., Ltd.

is trying to handle power lithium batteries with physical methods, and disassemble the waste battery pack to disassemble into original materials, and then recover, because this method does not involve chemistry. Processing, therefore can get an EIA license. But Guo Jie also said that it is necessary to build a production line of about 3,000 tons of annual recovery capacity, and it is necessary to invest 30 million yuan.

In addition, there is also a suspicion of the engine insiders to recover the dismantling of the dynamic lithium battery. It is believed that it is difficult to completely separate the various chemical materials that have been mixed without chemical treatment. The industrial chain must be combined to promote the recycling rate of the dynamic lithium battery can be improved.

It is not possible to resolve the process of recovering the decomposition. As a powered lithium 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. Utilization, even if it can be dismantled, there will be a lot of steps, and the time is expensive.

"Guo Jie also said that although the" Interim Measures for the Recycling Management of New Energy Automobile Power Battery "(hereinafter referred to as" Interim Measures) is expected to implement this year, the previously produced battery pack is not included in the "Interim Measures" Management, traceability, and battery pack can be more demandable, this part of the waste battery is still very difficult. As the drafting unit of "Interim Measures", my country's Automobile Technology Research Center (hereinafter referred to as "Sports Center") said that the scrap disassembly of the power lithium battery must strengthen the source control, implement the production of the production person's responsibility, let the car production The company undertakes the main responsibility of the recycling of dynamic lithium batteries. The battery production company guarantees the effective utilization and environmental treatment of the power lithium battery, and this is the basic principle of "Interim Measures".

Li Zhenyu, Engineering Engineer, Department of Automobile Industry Policy, said that the scrap recycling of power lithium batteries will adhere to the full life cycle concept, give full play to market use, the core measures of the "Interim Measures" are coding and traceability management, establish a unified power lithium battery Product coding standard, traceable information management system and related information sharing mechanism; ensure that power lithium battery products can be checked, go to the chasing, node controllable. Zhang Ying also said that the "Interim Measures" clarifies that the dynamic lithium battery design, access, production, sales, maintenance is replaced to the number of requests and recycling and utilization, and also put forward the punishment mechanism. If it can be smoothly landed, strict implementation will promote power Regular ordered development of lithium battery recycling.

"But there is still very uncertainty in supervision and market operation standards.". Zhang Ying said.
