Abstract

A one-step synthesis procedure is developed to prepare flexible S_0.6 Se_0.4 @carbon nanofibers (CNFs) electrode by coheating S_0.6 Se_0.4 powder with electrospun polyacrylonitrile nanofiber papers at 600 °C. The obtained S_0.6 Se_0.4 @CNFs film can be used as cathode material for high-performance Li-S batteries and room temperature (RT) Na-S batteries directly. The superior lithium/sodium storage performance derives from its rational structure design, such as the chemical bonding between Se and S, the chemical bonding between S_0.6 Se_0.4 and CNFs matrix, and the 3D CNFs network. This easy one-step synthesis procedure provides a feasible route to prepare electrode materials for high-performance Li-S and RT Na-S batteries.

Keywords: Li-S batteries; RT Na-S batteries; S0.6Se0.4; flexible; one step.
