A simple and versatile method for preparation of hierarchical sodium bismuth sulfide (NaBiS2) nanostructures is developed via a simple solvothermal route.

NaBiS2 is found to be characteristic of high capacity and low potential versus Na/Na+, which would be a promising anode material for sodium-ion battery.

Abstract

A simple and versatile method for preparation of hierarchical sodium bismuth sulfide (NaBiS2) nanostructures is developed via a simple solvothermal route. They were firstly tested as anode materials for sodium-ion battery. NaBiS2 is found to be characteristic of high capacity and low potential versus Na/Na+, which would be a promising anode material for sodium-ion battery. The NaBiS2 nanoparticles electrode delivers a second discharge capacity of 692.4 mA h g−1 at a current density of 10 mA g−1. A possible electrochemical reaction mechanism was proposed.
