α-MoO_3 nanostructure synthesized in plasma by an original method of pulsed high-voltage discharge as highly reversible anode for secondary lithium-ion battery

摘要

A new concept for synthesis of the nanostructured transition metal oxides had been proposed. In particular, the method of pulsed high-voltage discharge was adopted for synthesis of a-MoO_3 nanostructure with orthorhombic crystal lattice. The as-prepared α-MoO_3 was investigated as anode for Li-ion battery. The 30-fold charge-discharge cycling has shown that material specific capacity (approximately 90 mAh g~(-l)) is not high, however excellent reversibility was achieved (the Coulombic efficiency equals to 99.9%). Thus the method opens new ways for the synthesis of nanomaterials with stable reversible capacities for Li-ion batteries.
