What are the difficulties facing battery recycling?

Battery recycling is a difficulty and an outlet. At the same time, many new energy car companies are also actively looking for a way out for retired power lithium-ion batteries. At the new energy vehicle power lithium-ion battery recycling system construction forum held in Beijing at the end of October, 11 new energy vehicle processing companies, including FAW, Dongfeng, and BYD, signed a letter of intent for cooperation in the construction of a power battery recycling system with my country Tower Co., Ltd. In-depth cooperation in the field of power lithium-ion battery recycling. Li Li, an inspector of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, said that accelerating the construction of a waste power battery recycling system is an urgent and arduous task. All localities must actively explore in order to form a market-oriented recycling model with strong technology and economy and resource and environment friendly. However, under the background of policy support and the company's active response, my country's power lithium-ion battery recycling efficiency is low (only 2% in 2015, less than 20% in 2016). The issue of battery recycling has become increasingly prominent. Since 2011, the my country Association of Automobile Manufacturers has begun to announce the production and sales of new energy vehicles. This year is also recognized as the year when domestic new energy vehicles began to be sold. With the help of the country's favorable policies, the production and sales of domestic new energy vehicles have achieved a substantial increase. In 2011, the domestic sales of new energy vehicles was only 8,000, but in 2015 it increased sharply to 331,000, and by 2017, it had reached 777,000. The large-scale promotion of new energy vehicles has also led to a concentrated outbreak of the recycling and utilization of power lithium-ion batteries. According to the service life of commercial vehicle power lithium-ion battery of 3-5 years, and the service life of private car power lithium-ion battery of 5-8 years, the first batch of power lithium-ion batteries put into use has been in use for eight years, and they have begun to enter Retirement period. Fortunately, in the past few years, the promotion of new energy vehicles has been slow, so the number of retired power lithium-ion batteries is not large. But is this really the case? Although the battery life of new energy commercial vehicles is advertised as 3-5 years, in actual operation, many batteries cannot do it. According to the standards for the use of lithium-ion batteries for vehicle power, electric vehicle batteries are not suitable for continued use after the battery capacity drops to 80% of the rated capacity. According to our on-site surveys, it takes only two years or less for many commercial vehicle batteries to drop below 80%. The domestic battery recycling process is slow. In the early stage of the development of new energy vehicles, orders were mainly purchased by local governments, and the payment method was mostly adopted. If the car companies do not replace these scrapped batteries in a timely manner, it is very likely that they will not be able to get the final payment. Therefore, as far as we know, new energy car companies have always been more active in replacing these scrapped batteries. So where are the frequently replaced power lithium-ion batteries? Naturally still in the hands of car companies. Insiders mentioned this. If the above statement is true, the amount of power lithium-ion batteries to be recycled will be even greater. If these batteries are not handled properly, not only will it cause waste of resources and environmental pollution, but the significance of developing new energy vehicles will also be greatly reduced. However, up to now, a complete power lithium-ion battery recycling system has not been formed in China, and the related power lithium-ion battery recycling process and equipment are still in the initial stage of crossing the river by feeling the stones.
