Abstract

WS₂@graphene nanocomposites were synthesized by a hydrothermal approach. When applied as anodes in Na-ion batteries, the WS₂@graphene nanocomposite exhibited a high reversible sodium storage capacity of about 590 mA h g⁻¹. It also demonstrated excellent high rate performance and cyclability.
