Abstract: As a kind of lithium-ion battery cathode material，cobalt oxide（Co3O4） has been researched extensively.In recent years，improvement for the performance of Co3O4 has always been one of the hot spots in investigation domain of lithium-ion battery.The latest research advances in Co3O4 as cathode material for lithium-ion batteries was reviewed.The discussion was made from the aspects，such as structure，charge-discharge mechanism，synthetic method，and cornpound modification.It also indicated the development tendency of Co3O4 as cathode material for lithium-ion batteries in future.

Key words: Co3O4, cathode material, lithium-ion batteries, synthesis method
