According to the Voice of my country, "Yangguang News" reported that with more and more environmental issues, new energy vehicles are constantly being promoted in more countries. At the same time, the industry expects that the 2015 new energy vehicle battery accumulated volume is about 2-4 million tons. Recycling and reuse of new energy vehicle power lithium-ion batteries have become a problem that cannot be ignored.

The service life of the power lithium-ion battery is about 20 years, but it is only 3-5 years, because its capacity is attenuated to 80% of the initial capacity, the battery life will be significantly reduced. The power lithium ion battery 3-5 years must be replaced, so the price of price is also limited to the importance of electric vehicle promotion. According to experts from my country Automotive Technology Research Center, it is expected that by 2015, my country's power lithium-ion battery accumulated scrap volume is approximately 2-40,000 tons.

Before 2020, my country only pure electric passenger cars and hybrid passenger cars. Power lithium-ion battery accumulated scrap volume will reach 12-17 million tons. The reporter learned that the technical route of the recycling battery is quite complicated, such as in the treatment of waste lithium ion batteries, first to pretreatment, including discharge, disassembly, pulverization, sorting, plastic after disassembly, and iron housing It can be recovered; then the electrode material is leached, the acid is immersed, and the extract is then carried out.

This complex procedure makes many recycling companies. From the current situation of Europe and the United States, some manufacturers are vigorously promoting the use of dynamic lithium-ion battery recycling, and technical reserves for large-scale commercial recycling. For example, Belgian Jimei Company has developed ultra-high temperature technology to handle waste lithium-ion batteries.

And Toyota Motor Company is also working with Qi Mime, and recovert the lithium-ion battery of Toyota. A company in the United States is reversed, it uses liquid nitrogen to treat lithium-ion batteries in ultra-low temperature environments, so that its chemical properties become unactivated. Even the Germany of the dynamic lithium-ion battery manufacturer is also attached to the construction of the recycling network system.

It is understood that my country's motivational lithium-ion battery research is important to focus on improving its safety performance and service life, and the recycling link is quite small, or even seriously disconnected. The lithium ion battery as a power lithium ion battery contains a large amount of toxic heavy metal elements such as mercury, cadmium, lead, and its positive and negative electrode materials, electrolyte solutions and other substances have considerable impact on the environment, and the number of tens of thousands of tons per year will be Derfection is indeed a problem. As electric vehicles need to rise in full rising, to 2017 lithium electricity will not be available, so domestic experts call for the early research of dynamic lithium-ion battery recovery and reuse, and set up special recycling institutions.
