Abstract

Described herein are solid solution composites that are used as cathode materials for lithium-ion batteries. The solid solution composite of α LiMVO-βLiNiCoMnO, in which LiMVOhas cubic close-packed structure, LiNiCoMnOhas hexagonal layered structure, and both share an oxygen lattice fully or partly. The new solid solution materials have advantage for lithium-ion batteries that the working voltage of the composite is adjustable by controlling the molar ratio of α and β and have higher working voltage than current secondary battery materials. Also described herein are methods of preparing such composite.
