Aalto researchers discover LiCoO2 electrodes can be recycled without crushing or melting

Green Car Congress

Researchers at Aalto University in Finland have discovered that Li-ion battery electrodes containing cobalt (LiCoO 2 ) can be reused as is after being newly saturated with lithium. Kallio believes that with further development the method would also work on an industrial scale. Lahtinen, K., Rautama, E., Räsänen, S. and Kallio, T.
