A novel synthesis towards a vanadium pentoxide porous nanodisk film as a cathode material for advanced Li-ion hybrid capacitors

Chem Commun (Camb). 2019 Dec 17;56(1):70-73. doi: 10.1039/c9cc06958e.

Abstract

A V2O5 porous nanodisk thin film is synthesized through a simple hydrothermal and subsequent VO2 template oxidation strategy. For the first time, V2O5 is employed as a cathode rather than an anode to construct lithium-ion hybrid capacitors. This design effectively utilizes the intrinsic layered structure of V2O5 for facile Li+ intercalation and facilitates the charge balance with the capacitive electrode, enabling superior performance of the device.
