MoO3 nanosheets anchored in N-doped reduced graphene oxide as superior anodes for high-performance lithium storage

Molybdenum trioxide (MoO₃) possesses unique layered structure with high theoretical capacity and good environmental friendliness, which has been widely investigated as a potential anode material. Herein, MoO₃ nanosheets anchored in N-doped reduced graphene oxide (MoO₃/NG) composite was constructed and prepared through hydrothermal reaction and post-calcination. The introduction of NG matrix can enhance the electronic conductivity and accelerate reaction kinetics of the MoO₃, and solve the problem of severe capacity decay caused by its volume changes. MoO₃/NG composite can deliver superior cycling performance (900.2 mAh g⁻¹ at 0.2 Ag⁻¹ after 100 cycles and 407.5 mAh g⁻¹ at 10.0 Ag⁻¹ after 500 cycles) and fast reaction kinetics with high diffusion coefficients and low charge transfer resistances. Moreover, the excellent electrochemical performance of the full battery lays a solid foundation for subsequent commercial application research.
