Title
Synthesis of graphene-like MoS2 nanowall/graphene nanosheet hybrid materials with high lithium storage performance
Abstract

•GL-MoS2 nanowall/GNS nanocomposites are prepared by solvothermal method.•GL-MoS2 nanowall/GNS nanocomposite had more robust structures.•The composites provided a short pathway for both Li-ion and electrons diffusion.•The composites displayed excellent performance including rates and cyclability.

A facile method to synthesize graphene-like MoS2 nanowall/graphene sheet (GL-MoS2 nanowall/GNS) composites has been developed through a solvothermal method, and followed by annealing at 400 °C under Ar. The characterization results indicate that the thin flaky wall type GL-MoS2 nanowall was supported well on the crumpled graphene flakes with good dispersion. The as-obtained nanowall-nanosheet hybrids are more robust and still retain the reversible capacity of 700 mA h g−1 after 100 cycles at a charge–discharge rate of 500 mA g−1. The outstanding performance in electrochemistry is attributed to both the robust nanocomposite structure and the synergistic interactions between graphene and GL-MoS2 nanowall, which makes it an efficient stable lithium storage material.
