As the power battery average retirement period of 5-8 years, according to the China Automotive Technology Research Center predicted that by 2020, China's electric car battery scrap total will reach 120,000 -17 million tons. While other research institutes predict the data is even higher, then the amount of scrap will exceed 248,000 tons, which is about 20 times the amount of scrap in 2016. How to deal with the battery has become a big problem.

On January 4, 2018, China Tower Company signed 16 contracts with Changan, Chongqing Changan, BYD, Silver Long Energy, Watermark, Guoxuan Transtech Services and Thornton New Energy in Beijing to recycle the power batteries of new energy vehicles The purpose of the agreement is to strengthen the cooperation with backbone enterprises in automobile manufacturing, battery production, bus transportation, recycling and other industries to reduce the pollution caused by batteries of new energy vehicles.

According to previous reports, the new energy vehicle battery "dismantling norms" was released in May 2017 and will be implemented soon. According to the statistics from the Ministry of Science and Technology, as of 2017, the number of new energy vehicles in our country has exceeded 1 million, accounting for 50% of the total amount of new energy sources in the world. According to new energy battery 5-8 years of service life calculation, there are already some new energy vehicles will face the problem of battery recycling.

Most car prices to consumers commitment to battery life and warranty mostly in less than 10 years. For example, BYD and Daimler joint venture production of the first pure electric vehicle tide life of up to 300 km, Teng potential battery is lithium iron phosphate battery, the official guarantee of 4000 times after the charge and discharge to save 80% of the battery capacity, the battery Warranty period of 6 years or 150,000 km; Model S drive and battery pack warranty is 8 years unlimited mileage, as long as the user purchased the car has not been more than 8 years, the drive and the battery pack after a problem, Can enjoy free warranty service.

However, the higher frequency of use of battery packs, such as taxis and buses, may result in faster demand.

New energy vehicles have been on the issue of battery pollution has been a dispute, the country has no complete system to ease the flow from the car manufacturer to battery recycling business. The battery recycling project led by China Tower Corporation, or in the future to achieve from the manufacturing, recycling, secondary use of standard procedures, to address the battery pollution problems, to some extent, can also help new energy vehicles to improve certain secondary handicrafts value.
