Layer structural MoO2/carbon hybrid composites as anode materials for lithium-ion batteries

Layer structural MoO 2 /carbon hybrid composites (LMC) were prepared via simply two-step method by using organic–inorganic MoO 3 /(dodecyl amine, DDA) as precursor followed with annealing at 600 °C under reducing atmosphere. As an anode material, the hybrid composites deliver a good capacity of 675 mAh/g after 60 cycles and show a much better performance in cycling and rate capability than that of bare MoO 2 . The significant improvement may be partially ascribed to the layered structure of the composites, which is beneficial for diffusion of Li + by decreasing the diffusion path lengths. In addition, combining carbon with MoO 2 improves the electronic conductivity of composites and maintains the mechanical integrity of electrode, thus decreases the mechanical degradation and pulverization. The presented work provides a strategy to design and prepare electrode carbon-containing electrode materials for better energy storage properties.
