Construction of hierarchical MoSe2@C hollow nanospheres for efficient lithium/sodium ion storage

Author affiliations

Abstract

MoSe2 has been recognized as a promising anode material for lithium/sodium ion batteries due to its unique structure and material properties. Here, hierarchical MoSe2@C hollow nanospheres (MoSe2@C HNSs) assembled with ultrathin nanosheets are prepared via a facile solvothermal method. The MoSe2@C HNS composite is fabricated by an anion-exchange reaction from Mo-glycerate solid spheres combining with the carbonization of glucose. When used as an anode material for LIBs, the MoSe2@C HNS composite manifests a reversible capacity of 711 mA h g−1 after 300 cycles under a current density of 500 mA g−1. When evaluated as an anode material for SIBs, the MoSe2@C HNS composite delivers a high capacity of 683 mA h g−1 at 100 mA g−1 and maintains a capacity of 458 mA h g−1 after 200 cycles at 200 mA g−1. The efficient lithium and sodium ion storage performance should be ascribed to the unique hierarchical hollow nanostructure and synchronously incorporated carbon material.
