title: A Safe High-Performance All-Solid-State Lithium-Vanadium Battery with a Freestanding V2O5Nanowire Composite Paper Cathode.
abstract: The electronic conductivity and structural stability are still challenges for vanadium pentoxide (V2O5) as cathode materials in batteries. Here, we report a V2O5nanowire-reduced graphene oxide (rGO) composite paper for direct use as a cathode without any additives for high-temperature and high-safety solid polymer electrolyte [PEO-MIL-53(Al)-LiTFSI] lithium-vanadium batteries. The batteries can show a fast and stable lithium-ion-storage performance in a wide voltage window of 1.0-4.0 V versus Li+/Li at 80 °C, in which with an average capacity of 329.2 mAh g-1at 17 mA g-1and a stable cycling performance over 40 cycles are achieved. The excellent electrochemical performance is mainly ascribed to integration of the electronic conductivity of rGO and interconnected networks of the V2O5nanowires and solid electrolyte. This is a promising lithium battery for flexible and highly safe energy-storage devices.
