One pot hydrothermal synthesis of graphene like MoS2 nanosheets for application in high performance lithium ion batteries

Abstract

In this paper, we develop a simple one pot facile technique to synthesis few layer MoS₂ nanosheets through an aqueous hydrothermal method using L-cysteine as the sulphur source. The high resolution transmission electron microscopy shows that the as-synthesized MoS₂ nanosheets exhibit well crystallized few layer graphene like structures ten of nanometers in size. The experimental results indicate that few layer MoS₂ nanosheets exhibit the highest specific reversible capacity of 1097 mA h g⁻¹ at a current density of 50 mA g⁻¹ after 25 cycles. The excellent electrochemical properties are attributed to the synergistic effect of the few layer MoS₂ nanosheets.
