Abstract CuCo 2 S 4 hollow spheres are synthesized from CuCo 2 O 4 hollow spheres without destroying the hollow structure, and N/S doped graphene is coated simultaneously through an electrostatic self-assembly method. Benefiting from the simultaneously design of composition and structure of mixed metal sulfides, the composite exhibit excellent cycle stability and rate capability.
