Amorphous Pathway for Cathode Regeneration.

Caption

Schematic illustration of the regeneration process for heavily degraded lithium cobalt oxide (LCO) cathodes. Through ball milling, the spinel-phase structured spent LCO (SLCO) is transformed into an amorphous intermediate (rLCO), facilitating lithium replenishment and structural restoration. Subsequent treatment with LiOH enables the formation of regenerated LCO (RLCO) with restored layered architecture and electrochemical performance.
