Transition metal chalcogenides as a promising anode material with high theoretical capacity has attracted more and more attention. This thesis focuses on a facile method to synthesize hollow Co3O4 encapsulated by carbon layers (Co3O4@C) with polydopamine as precursor, after reacting with thioacetamide and (NH4)(6)Mo7O24 center dot 4H(2)O, hollow rhombic dodecahedral shape Co3S4@C@MoS2 heterostructures are successfully fabricated and employed as the anode of lithium-ion battery. Benefiting from the typical layered structure of Co3S4@C@MoS2 heterostructures, the stability and capacity have been significantly improved, with a high capacity of 672.6 mAh g(-1) after 200 cycles at the current density of 0.2 A g(-1). The excellent electrochemical properties of hollow Co3S4@C@MoS2 heterostructures are ascribed to the consolidate of Co3S4, carbon and MoS2, and the stability of the composite structure.
