Interconnected MoO2 Nanocrystals with Carbon Nanocoating as High-Capacity Anode Materials for Lithium-ion Batteries

A facile one-pot hydrothermal method has been developed for the preparation of carbon-coated MoO2 nanocrystals. The annealed MoO2-C nanocomposite consists of interconnected MoO2@C nanocrystals. When evaluated for lithium storage capabilities, these MoO2@C nanocrystals exhibit high specific capacities (similar to 640 mA h g(-1) at 200 mA g(-1) and similar to 57.5 mA h g(-1) at 400 mA g(-1)) and excellent cycling stability. In view of the excellent lithium storage properties and the ease in large-scale preparation, the as-synthesized MoO2-C nanocomposite might be used as promising anode materials for high-performance lithium-ion batteries.
