Interpretation of the recovery and reuse of lithium-ion batteries for new energy vehicles

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, the total scrap of new energy vehicle batteries was about 20,000 to 40,000 tons. The recycling of lithium-ion batteries for new energy vehicles has become an issue that cannot be ignored. The service life of the power lithium battery is about 20 years, but for cars, it can only be cancelled within three to five years, because its initial capacity attenuation is less than 80%, and the range of electric vehicles will be significantly reduced. The battery 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 estimates by experts from the my country Automotive Technology Research Center, in 2015, my country’s total scrapped batteries were about 20,000 to 40 thousand tons. By 2020, the total amount of scrapped batteries for pure electric passenger vehicles and hybrid electric passenger vehicles in my country will reach 120,000 to 170,000 tons. The reporter knows that the technical route of recycling batteries is quite complicated. For example, in the treatment of waste lithium batteries, it must first be pre-processed, including discharge, disassembly, crushing, and sorting; plastic and iron casings can be recycled after disassembly; then The electrode material is extracted by alkaline leaching method and acid leaching method, and then extracted through various processes. The complexity of the process discourages many recyclers. Judging from the current situation in European and American countries, some manufacturers are vigorously promoting the research and utilization of the recycling of power lithium-ion batteries in order to reserve large-scale commercial recycling technologies. For example, the Belgian company meinecke has developed ultra-high temperature technology to dispose of used lithium batteries. Toyota Motor Corp. is also cooperating with Toyota Motor Corp. to recycle lithium batteries. An American company did the opposite. They used liquid nitrogen to treat lithium batteries 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 known that the current research on power lithium-ion batteries in my country is mainly focused on improving their safety performance and service life, with relatively few recycling links and even serious disconnections. Lithium batteries, power lithium-ion batteries, contain a large amount 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, thousands of tons per year. It is indeed a problem in the future. With the overall increase in the demand for electric vehicles, lithium batteries will be in short supply by 2017. Therefore, domestic experts call for preliminary research on the recycling of power lithium-ion batteries and the establishment of special recycling agencies. 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, the total scrap of new energy vehicle batteries was about 20,000 to 40,000 tons.
