In short, the recovery of cobalt and lithium from Li-ion batteries and the synthesis of LiCoO 2 are conducted in two individual systems and harmful chemicals or high temperatures or pressures are usually used. A more environmentally benign, shorter, and easier process is still urgently needed.
The study aimed to maximize the yield of lithium and cobalt from the black mass of spent Lithium-Ion Batteries (LIBs) through an optimized high-temperature thermal pretreatment process, which combined mechanical (direct crushing) and thermal treatments to facilitate the subsequent recovery of these valuable metals.
This study compares pretreatment methods for spent lithium-ion batteries (SLIBs), focusing on direct crushing and thermal treatment with subsequent crushing. Direct crushing of spent LIBs liberates active materials from current collectors, with extended crushing times enhancing material breakdown into finer particles.

This paper aims to employ a molten ammonium sulfate ( (NH4) 2 SO 4) assisted roasting approach to recovering and regenerating LiCoO 2 from spent lithium-ion batteries (LIBs) at 400 °C. First, cathode materials from the spent LIBs are converted to CoSO4 and Li 2 SO 4 via a sulfation roasting approach.
