Battery-grade lithium compounds are high-purity substances suitable for manufacturing cathode materials for lithium-ion batteries. The global production of cathode materials includes LiFePO 4, Li 2 MnO 4, and LiCoO 2, among others. Usually, the starting raw material is Li 2 CO 3, followed by lithium hydroxide monohydrate LiOH·H 2 O and LiCl .
Bulk molybdenum oxides, however, show much lower capacities compared with their theoretical ones, which can be attributed to the significant volume change during the charge and discharge processes and the intrinsic slow kinetics for the conversion reactions 5.
