The PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC method for regenerating waste LITHIUM ion battery graphite anode MATERIAL includes the following steps :(1) waste LITHIUM ion battery anode MATERIAL is added into acidic solution and fully mixed, and then the waste graphite powder and LITHIUM rich solution are separated from the solid and liquid; (2) After mixing additives in waste graphite powder and ball milling treatment, the regenerated graphite anode material doped with additives containing groups, the treatment time is not less than 6h.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC regeneration method, easy operation, high efficiency and low cost; The regenerated graphite anode materials obtained by the regeneration method have excellent physical and chemical properties and electrochemical performance, and realize the efficient utilization of graphite anode materials for spent lithium ion batteries.
Artificial graphite anode material meets the requirements of cycle life and safety of power batteries and energy storage batteries, so it will still be the mainstream application direction of power batteries and energy storage batteries for a long time. According to data from lithium batteries, the CAGR of anode materials was 33.07% from 2016 to 2020, while the CAGR of artificial graphite anode materials was 39.71%, which was higher than the CAGR of anode materials.
