Methods for valuable resource recovery from cathode materials of spent lithium ion battery

The lithium-ion battery has a wide range of applications for its excellent performance.However,the abandoned used lithium-ion battery is also increasing.Without effective treatment,spent lithium-ion batteries will bring great pressure to the environment by wasting resources.This article introduces the major constituent of the lithium-ion battery and necessity of recycling.This paper also introduces in detail the current methods for valuable resource recovery from cathode materials of spent lithium-ion battery.Finally,the problem in the recovery of spent lithium-ion battery is proposed and the future development direction of spent lithium-ion battery is prospected.From the perspective of economy and environmental protection,spent battery material process is most likely to become future research focus.
