With more and more countries attach importance to environmental protection, new energy vehicles are developing and promoting more and more countries. At the same time, the industry is estimated that the 2015 new energy vehicle battery has scandable about 2-400 tons. Recycling of new energy vehicle power lithium-ion batteries has become a problem that cannot be ignored.

Dynamic lithium-ion battery life is about 20 years, but the car will only be canceled within three to five years, because its capacity attenuation is less than 80%, the range of electric vehicles will be significantly reduced, and lithium The ion battery must be replaced every 3 to 5 years, 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, 2015 my country's accumulated scrap battery is about 2-400 tons. Around 2020, my country's pure electric passenger car and hybrid passenger car accumulated a total scrap battery will reach 12-17 million tons.

The reporter learned that the technical route for recycling batteries is quite complicated. For example, in the processing of waste lithium-ion batteries, it is first necessary to prepare them, including discharge, disassembly, breaking, sorting, and recoverable after the plastics and iron housings are removed; The electrode material is then extracted with alkali dipping, acid immersion method, and then extracts various processes. The complexity of the process makes many recycling, but.

From the current situation of Europe and the United States, some manufacturers are vigorously promoting the recycling research and utilization of dynamic lithium-ion batteries, which is a large-scale commercial recycling technology. For example, Belgium MEINECKE has developed ultra-high temperature techniques to handle the used lithium-ion battery. Toyototamotorcorp.

) Is also working with Toyototamotorcorp. To recover lithium-ion batteries. The practice of a US company is just contrary, they use liquid nitrogen to treat lithium-ion batteries under ultra-low temperature to make it chemically inert.

Even in Germany, there is still no battery manufacturer, is also building a recycling network. It is understood that my country's research on dynamic lithium-ion batteries is currently increasing its safety performance and service life, and the recovery link is relatively small, and even severely disconnected. Lithium-ion battery, powered lithium-ion battery, contains a large amount of toxic weights such as mercury, cadmium and lead, and their anode and cathode materials, electrolyte solutions and other substances have considerable impact on the environment, thousands of tons per year The quantity is indeed a problem in the future.

With the overall rise of electric vehicles, lithium-ion batteries will supply in short supply, so domestic experts call for early research on dynamic lithium-ion battery recycling issues, establish special recycling institutions. With more and more countries attach importance to environmental protection, new energy vehicles are developing and promoting more and more countries. At the same time, the industry is estimated that the 2015 new energy vehicle battery has scandable about 2-400 tons.
