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.
