With the expansion of new energy automotive industries, my country has become the world's largest lithium-ion battery producer. As a result, the flow of subsequent discarded dynamic lithium-ion batteries also causses wide attention. my country is exploring new energy battery recycling management system.

Recently, Miao Wei, Minister of the Ministry of Industry and Information Technology, said that the recycling and utilization of new energy vehicle power lithium-ion batteries will establish a production person responsibility extension system. The automobile production plant is responsible for the recycling of the battery when selling new energy models. On October 19th, the audience visited the liquid cooling battery of the new sports car in my country's international energy conservation and new energy auto show.

Xinhua News Agency (Chen Xiaomeng photo) According to the plan, my country's new energy vehicle accumulated production and sales will reach 5 million vehicles in 2020. Due to the average of the power-based lithium-ion battery, it is 5-8 years. According to the research institute of high-rise, China's high-rise, my country's powered lithium-ion battery will usher in the "reporting waste".

By 2020, the report will exceed 248,000 tons. About 20 times more reported in 2016. These scrap batteries are not properly handled, not only cause waste of resources, but also more likely to pollute the environment.

How to safely recycle, environmentally friendly, strengthen the standardized circular utilization of waste dynamic lithium-ion batteries, and become the "world-oriented problem" that industry people are generally concerned. On June 22, Hebei AUCD power supply limited liability company workers operate on the power lithium-ion battery. Xinhua News Agency reporter Li Xiaozuo's recycling of lithium-ion batteries is divided into two cycle processes for ladder utilization and dismantling recycling.

The power lithium ion battery performance will attenuate as the number of charging changes, when the battery capacity is attenuated to 80% or less of the rated capacity, the power lithium ion battery is not suitable for the application of electric vehicles. The ladder use refers to the use of the powerful lithium-ion battery that will be retired, and uses in the fields of energy storage, distributed photovoltaic power generation, low-speed electric vehicles. When the battery is unable to use the ladder, the disassembly recycling is required.

Xu Shengming, a researcher of the Nuclear Energy and New Energy Technology Research Institute of Tsinghua University, believes that the recycling of the useful power lithium-ion battery resources is huge. "Currently in the technical accumulation and development phase. In the future, recycling technology and ladder use technology innovation is an important representation of the company's competitiveness.

"Some new energy car companies, power lithium-ion battery manufacturers to step up layout dynamic lithium-ion battery recycling field. Beiqi new energy has been built in Hebei to build battery steps and battery harmless treatment. The rare precious metal refinery is convenient to re-use the lithium-ion battery by physics, chemistry.

Dynamic lithium-ion battery company Ningde Times Explore the complete lithium-ion battery green industry chain: Dynamic lithium-ion battery After retiring from the car, when the battery capacity is 70% to 80%, it is placed in its battery energy storage system for the ladder After the ladder is used, the battery will be disassembled and the battery material is recovered. Green Mei's Identification Battery Circulating Renewal Three Dynamic Lithium Ion Battery Material Production Line. The picture was supplied by Greenmeal Co.

, Ltd., although some new energy car companies have lay out of the dynamic lithium-ion battery recycling market, but due to the shortcomings of technology and related experience, many companies choose to hand over the professional recovery power lithium-ion battery. Green Mei Co.

, Ltd. and BYD, Dongfeng and other new energy automobile manufacturers cooperate to solve the power lithium-ion battery recycling. According to Zhang Yuping, deputy general manager of the company, Green Mei has the largest waste battery and scrap battery material processing production line in China.

Based on the original battery recovery system, key layout dynamic lithium-ion battery recycling business. At present, 83 related patents have been applied, participate in the development of national standards such as recycling and utilization of car power lithium-ion batteries. "We extracted metal, cobalt, etc.

, for resource utilization by dismantling, breaking, separating, purifying, smelting, smelting, making resource utilization, to achieve resource utilization, thereby achieving dynamic lithium ion battery materials from waste cells to new batteries Circular reconstruction. "Zhang Yuping said. According to Xu Shengming, the raw materials such as cobalt, nickel, and lithium, such as the power lithium-ion battery are very important strategic resources.

At present, my country's 80% cobalt and 70% lithium, nickel resources depend on imports. "my country's cobalt resources are more poor, cobalt is less than a few thousand tons, but the amount of use reaches tens of thousands of tons, so it is basically imported. New energy automotive industry has developed very fast, cobalt has been supplying.

Xu Shengming said. Greenmei has the world's largest waste battery and cobalt nickel tungsten resources circulation. "Through mining city mines, Green Mei recovers 5,000 tons of cobalt metal every year, more than my country's cobalt mining.

"Zhang Yuping said that with the expansion of the future power lithium-ion battery, the source of cobalt metal will be important from the recycling field. Zhang Yuping also pointed out that the current amount of scrap in my country's waste dynamic lithium-ion batteries is still small, the recycling channel and the recycling system are still immature, and the treatment and disposal of the waste dynamic lithium-ion battery is still in the market and technical development. In terms of dynamic lithium-ion battery recovery, transportation, dismantling, ladder utilization, material regeneration and harmless treatment, etc.

, to explore business models, speed up breakthrough technical problems, and achieve relevant results as soon as possible to respond to subsequent waste Dynamic lithium-ion battery continuous rise. From 1 December this year, "The Demolition Specification for Car Power Lithium Ion Battery Recycling" will be officially implemented, which is the first national standard proposed by the Ministry of Industry and Information Technology, which is clearly indicated by the recycling dismantling. Companies should have relevant qualifications.

The powerful lithium-ion battery recovery policy is expected to increase, but also gave the market greater confidence. Zheng Mianping, academician of our engineering, believes that the waste of lithium-ion batteries have significant resource, and effective recycling is both economic significance. "The mine production of raw materials, metal recycling should be much better, there is also a great advantage in energy conservation and emission reduction, so the recycling of dynamic lithium-ion batteries is related to the construction of low-carbon economy and environmentally friendly, and the country has vigorously promoted dynamic lithium ions.

Battery recycling is imperative. "Zheng Mianping said. .
