摘要:
An all-vanadium-based lithium-ion full battery is successfully assembled with hierarchical micro-nano yolk-shell structures V2O5 and V2O3 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 V2O5 demonstrated higher capacities than bulk V2O5, commercial LiFePO4, and LiNi0.8Co0.1Mn0.1O2 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.
