An all-vanadium-based lithium-ion full battery with hierarchical yolk–shell structure electrodes
An all-vanadium-based lithium-ion full battery is successfully assembled with hierarchical micro-nano yolk-shell structures V<sub>2</sub>O<sub>5</sub> and V<sub>2</sub>O<sub>3</sub> as the cathode and anode, which were obtained through a facile solvothermal method with heat treatment under different atmospheres. When used as the cathode of the lithium-ion battery, the hierarchical micro-nano yolk-shell V<sub>2</sub>O<sub>5</sub> demonstrated higher capacities than bulk V<sub>2</sub>O<sub>5</sub>, commercial LiFePO<sub>4</sub>, and LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> cathodes at various current densities. The all-vanadium-based lithium-ion full battery shows good cycle performance at 0.1C and stable charge/discharge abilities at large current densities. The electrochemical performance of the full battery results from the low impedance and pseudocapacitance-dominated lithium storage mechanism derived from the micro-nano yolk-shell structure.
