As more and more countries attach importance to environmental protection, new energy vehicles are being developed and promoted in more and more countries. At the same time, industry insiders estimate that in 2015, about 20,000 to 40,000 tons of new energy vehicle batteries were scrapped. The recycling of new energy vehicle power lithium-ion batteries has become a problem that cannot be ignored.

The service life of the power lithium-ion battery is about 20 years, but the relevant car can only be cancelled within three to five years, because its initial capacity of capacity decay is lower than 80%, the range of electric vehicles will be significantly reduced, and the power lithium-ion battery will be significantly reduced. Ion batteries must be replaced every 3 to 5 years, so the high price also limits an important factor in the promotion of electric vehicles. According to the estimates of experts from my country Automotive Technology Research Center, in 2015, my country's accumulated scrapped batteries were about 20,000 to 40,000 tons. By around 2020, the cumulative amount of scrapped batteries for pure electric passenger vehicles and hybrid passenger vehicles in my country will reach 120,000-170,000 tons.

We have learned that the technical route of recycling batteries is quite complicated. For example, in the treatment of waste lithium-ion batteries, we must first pre-treat them, including discharge, disassembly, crushing, and sorting; plastic and iron shells can be recycled after disassembly; Then the electrode material is extracted by alkali leaching method and acid leaching method, and then extracted by various processes. The complexity of the process discourages many recyclers.

Judging from the current situation of European and American countries, some manufacturers are vigorously promoting the recycling research and utilization of power lithium-ion batteries to reserve large-scale commercial recycling technology. Belgian company meinecke, for example, has developed ultra-high temperature technology to process used lithium-ion batteries. Toyota Motor Corp. is also working with Toyota Motor Corp. to recycle lithium-ion batteries. A U.S. company is doing just the opposite, treating lithium-ion batteries with liquid nitrogen at ultra-low temperatures to make them chemically inert. Even Germany, which does not yet have a battery manufacturer, is building a recycling network.

It is understood that the current research on power lithium-ion batteries in my country mainly focuses on improving its safety performance and service life, and the recycling process is relatively small, or even seriously disconnected. Lithium-ion batteries, power lithium-ion batteries, contain large amounts of toxic heavy metals such as mercury, cadmium and lead, and their anode and cathode materials, electrolyte solutions and other substances have a considerable impact on the environment, with thousands of tons of Quantity will indeed be an issue in the future. With the overall increase in demand for electric vehicles, lithium-ion batteries will be in short supply by 2017. Therefore, domestic experts call for preliminary research on the recycling and utilization of power lithium-ion batteries and the establishment of special recycling institutions. As more and more countries attach importance to environmental protection, new energy vehicles are being developed and promoted in more and more countries. At the same time, industry insiders estimate that in 2015, about 20,000 to 40,000 tons of new energy vehicle batteries were scrapped. The recycling of new energy vehicle power lithium-ion batteries has become a problem that cannot be ignored.
