A nanowire-assembled Co3S4/Cu2S@carbon binary metal sulfide hybrid as a sodium-ion battery anode displaying high capacity and recoverable rate-performance

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...

Description
Summary: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.
