How to deal with used lithium-ion batteries

by：Vglory 2021-03-25

The use of wet process to dispose of waste lithium ion batteries is currently a more researched and relatively mature process, which has three important stages: 1) The recovered waste lithium ion batteries are subjected to pretreatment such as thorough discharge, simple separation and crushing, and screening Afterwards, important electrode materials are obtained or the electrode materials are obtained after crushing and roasting to remove organic matter; 2) Dissolving and leaching the electrode materials obtained after pretreatment, so that various metals and their compounds enter the leachate in the form of ions; 3) In the leachate There is separation and recovery of metals. This stage is the key to the treatment process of waste lithium-ion batteries, and it is also the focus and difficulty of researchers for many years. At present, the main methods of separation and recovery include solvent extraction, precipitation, electrolysis, ion exchange, and salting out.
