通过简单的水热和随后的VO2模板氧化策略合成了V2O5多孔纳米盘薄膜。首次采用V2O5作为阴极而不是阳极来构建锂离子混合电容器。这种设计有效地利用了V2 O 5的本征分层结构，易于Li+嵌入，并促进了与电容电极的电荷平衡，从而实现了器件的上级性能。
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.
