Electrodeposition of high-density lithium vanadate nanowires for lithium-ion battery
Lithium vanadate nanowires have been electrodeposited onto a titanium (Ti) foil by a direct current electrodeposition without template. The morphology, crystal structure, and the effects of deposition voltage, temperature and time on the prepared samples were tested and presented. The as-prepared lithium vanadate nanowires/Ti composite can be used as electrode for lithium-ion battery. Electrochemical measurements showed that the electrode displayed a specific discharge capacitance as high as 235.1 mAh g(-1) after 100 cycles at a current density of 30 mA g(-1). This research provides a new pathway to explore high tap density vanadates nanowires on metals with enhanced electrochemical performance. (C) 2018 Elsevier B.V. All rights reserved.
