Tailoring the electrochemical properties of composite electrodes by introducing surface redox-active oxide film: VO(x)-impregnated LiFePO4 electrode.
When the electrode is specifically designed by impregnation with an electronic and ionic mixed-conductor, improvement in the electrochemical properties was observed. The presence of an active redox center may contribute to the enhancement of the surface electronic/ionic transport properties by enhancing electrical connection and isotropic Li(+) ion transport.
