At present, there are two important methods for the recovery and utilization of power lithium battery. One is to disassemble the battery to extract metal and raw materials for recycling. For example, cobalt and nickel are relatively scarce resources in China, which can be recycled; The other is secondary or even multiple use.

As countries around the world have successively introduced the timetable for the delisting of fuel vehicles, it is a general trend for electric vehicles to replace fuel vehicles. But can electric vehicles really achieve "zero emission, zero pollution and environmental protection"? Although fuel vehicles are more environmentally friendly during the driving of electric vehicles, the subsequent treatment is the key when the electric vehicles are scrapped, especially the treatment of power lithium batteries.

As electric vehicles are driven by power lithium batteries, the disposal of power lithium batteries after scrapping of electric vehicles will be a global issue. At present, there are two important types of power lithium batteries, one is ternary lithium battery, the other is lithium iron phosphate. They all contain heavy metals such as cobalt, nickel, manganese and lithium. If these heavy metals are not handled properly, it will cause irreversible damage to the environment.

At present, there are two important methods for the recovery and utilization of power lithium battery. One is to disassemble the battery to extract metal and raw materials for recycling. For example, cobalt and nickel are relatively scarce resources in China, which can be recycled; The other is secondary or even multiple use. For example, Itochu Commercial Co., Ltd. of Japan converted the vehicle mounted lithium-ion battery into a battery, which is a good example. Put 16-20 pieces of waste vehicle batteries in a container to make a large battery. The battery pack can store up to 1000kW/h, which is equivalent to the power consumption of 100 ordinary households in one day.

With the popularity of electric vehicles, the number of waste power lithium batteries will continue to increase in the future, and the recycling of these power lithium batteries will certainly face greater challenges. Especially in China, at present, 5% of the global sales of pure electric vehicles are in China. While promoting the popularity of electric vehicles, attention should also be paid to the recycling of power lithium batteries.

Since China promoted new energy vehicles in 2009, the batteries of the first batch of new energy vehicles sold have been retired for nearly two years. According to the data of China Automotive Technology Research Center, the accumulated retired power lithium batteries in China in 2020 have exceeded 200000 tons, and it is estimated that about 60000 tons of batteries will be scrapped. But before that, there was no perfect legal system for the recycling of power lithium batteries. In order to prevent the improper treatment of these power lithium batteries from causing irreversible damage to the environment, the Ministry of Industry and Information Technology released the Industrial Norms and Conditions for the Comprehensive Utilization of Waste and Used Power Batteries of New Energy Vehicles (2019 version) and the Interim Measures for the Administration of Circular of Industrial Norms for the Comprehensive Utilization of Waste and Used Power Batteries of New Energy Vehicles (2-19 versions) in January 2020 to clearly regulate the supply of power lithium battery recycling industry.
