Thermochemically driven crystal phase transfer via chlorination roasting toward the selective extraction of lithium from spent LiNi1/3Co1/3Mn1/3O2

The selective extraction of lithium from spent lithium-ion batteries (LIBs) is significant for combating potential lithium deficiencies and for providing environmental protection by enabling highly selective Li extraction through a short path. Herein, we demonstrate a thermochemically driven process for spent LiNi1/3Co1/3Mn1/3O2 (NCM) batteries by systematically understanding the conversion mechanisms and controlling the chlorination behavior...
