1T–2H MoSe2/N-doped rGO composites as anodes for high performance lithium-ion batteries

Abstract

Lithium-ion batteries have been regarded as a promising power source for various electronic devices. Compared to the traditional graphite anode material, MoSe₂ possesses a higher theoretical capacity. However, MoSe₂ anode materials are limited by low electronic conductivity and large volume changes during cycling. This study reports 1T–2H MoSe₂/N-doped rGO nanocomposites, fabricated through a hydrothermal method. The 1T–2H MoSe₂/N-doped rGO electrode delivers a high reversible capacity of 483.6 mA h g⁻¹ after 1000 cycles at 1000 mA g⁻¹. It also possesses a high reversible capacity of 474.9 mA h g⁻¹ even at a current density of 2000 mA g⁻¹, thus, making it an important potential lithium-ion battery anode.
