Sheet-like MoSe2/C composites with enhanced Li-ion storage properties

Author affiliations

Abstract

Carbon–transition-metal dichalcogenide composites have demonstrated favourable properties for lithium-ion batteries. Herein, a sheet-like MoSe2/C composite was successfully synthesized using Na2MoO4·2H2O, Se powder and glucose as the source materials through a simple hydrothermal method and subsequent annealing treatment. The as-synthesized sheet-like MoSe2/C composite was characterized by XRD, FSEM, FTEM, and XPS. When fabricated into a lithium-ion battery, the composite exhibited improved Li storage properties compared to a pure MoSe2 electrode, including a good cycling stability and high rate capacity. After 50 cycles, a reversible specific capacity of about 576.7 mA h g−1 at a current density of 100 mA g−1 was still achieved for the sheet-like composite electrode.
