Reversible sodium storage via conversion reaction of a MoS2–C composite

Abstract

An exfoliated MoS₂–C composite (E-MoS₂–C) was prepared via simple chemical exfoliation and a hydrothermal method. The obtained E-MoS₂–C was tested as an anode material for sodium ion batteries. High capacity (∼400 mA h g⁻¹) at 0.25 C (100 mA g⁻¹) was maintained over prolonged cycling life (100 cycles). Outstanding rate capability was also achieved with a capacity of 290 mA h g⁻¹ at 5 C.
