Abstract

A binary metal sulfide hybrid consisting of nanowire-assembled and polypyrrole-coated Co₃S₄/Cu₂S spheres after nitrogen-doped carbon coating (Co₃S₄/Cu₂S@NC) is developed as an anode, which displays a capacity exceeding 412.3 mA h g⁻¹ after 550 cycles under 1.0 A g⁻¹. Recoverable rate-performance and good temperature tolerance under 50 °C and −10 °C are achievable; a full cell delivers 339.5 mA h g⁻¹, indicating promising potential for applications in various conditions.
