One-step synthesis of carbon-coated monocrystal molybdenum oxides nanocomposite as high-capacity anode materials for lithium-ion batteries

One-step synthesis of carbon-coated monocrystal molybdenum oxides nanocomposite as high-capacity anode materials for lithium-ion batteries

Benefitting from higher specific capacities, acceptable cost, nontoxicity and unique crystal structures, the molybdenum oxides have been studied as the anode materials for lithium ion batteries (LIBs). Herein, a direct current (DC) arc-discharge plasma technique has been developed to in-situ synthes...
