Recovery Of Cathode Material From Li-Ion Batteries

Abstract

This article focuses on the possibilities of recycling materials from spent Li-ion batteries,especially on direct recycling. Lithium-ion batteries (LIBs) are gradually replacing other types ofaccumulators from practical applications and further increase in their production is expected in thefuture. With high production, bigger amount of waste will have to be deal with. Recycling processescurrently in use are not efficient enough and they have been developed mainly for one type ofcathode material. Direct recycling is very promising in terms of efficiency, but it needs to be furtherenhanced. Direct recycling technology is discussed in the text as well as the recovery processfor commercial Samsung 18650B-20R aged cell using different kinds of solvents.
