Abstract

Herein, Zn doped VO₂ nanorods were successfully synthesized by a simple solvothermal method and a functional separator was presented by coating Zn doped VO₂ nanorods and graphene on surface of a commercial polypropylene separator. Owing to the function of the Zn-VO₂/G coated layer, the BP2000/S cathode with high sulfur content exhibited an initial discharge capacity of 1257.6 mAh g⁻¹ with a good cycling stability at 0.2C. In particular, the cathode exhibited an initial specific capacity of 1205.5mAh g⁻¹ at 1C and remained 509.4mAh g⁻¹ after 500 cycles. The functional separator reported in this work holds great promise for the development of high energy density Li-S batteries.
