What are the problems with the recycling of lithium battery packs?

1. Lithium battery recycling market tens of billions of blue ocean In recent years, the number of new energy vehicles market has been increasing day by day, as the core of new energy vehicles, the consumption of power lithium-ion batteries has naturally risen. In 2017, my country's new energy vehicle sales exceeded 700,000. It is reported that by 2020, the global sales of new energy vehicles will be close to 5 million, including 2 million in my country and 1 million in the United States. Looking at the world, new energy vehicles are showing a sustained high rise. It is estimated that by 2020, the total amount of waste power lithium battery packs in my country will reach about 200,000 tons. Industry forecast data shows that in 2018, the recycling market for waste power lithium-ion batteries can reach 5 billion yuan. From 2020 to 2023, the market for recycling lithium-ion batteries for waste power will further rise to 13.3-111 billion yuan. Its future direction can be described as It is very impressive. 2. Lithium battery recycling method: cascade utilization and disassembly recycling. The so-called cascade utilization refers to the use of high-power used batteries after inspection for low-power use. The principle is similar to what a battery advertisement says: toy car The used batteries and the remote control can still be used. At present, the cascade utilization is only for the lightly scrapped power lithium-ion batteries, which are applied to low-power electrical equipment to achieve the purpose of secondary utilization. The batteries that have reached a severe level of scrap after cascading use will enter the dismantling and recycling process. Dismantling and recycling, as the name suggests, is to dismantle, separate, purify, smelt and other waste batteries through chemical methods, and recycle and reuse the metal elements such as lithium, nickel, cobalt, and manganese in the batteries. 3. The importance of recycling of decommissioned lithium battery packs: (1) Cascade utilization can realize the secondary application of decommissioned power lithium battery packs in the field of energy storage. The downstream application space is huge, and it is also a recycling method that is supported by policies. Car companies and battery factories have inherent advantages, but they also face the dilemma of higher costs for recycling retired batteries. At the same time, this approach has extremely high requirements for battery consistency, and some demonstration projects are currently in operation; (2) Disassembly and recycling is currently an important current approach for the recycling of decommissioned lithium battery packs. Among them, wet recycling has the highest degree of commercialization, and the price of raw materials In the context of the general rise, locking the price of upstream raw materials through recycling + processing will be an important way for battery material manufacturers to reduce costs in the future.
