Enhancing interfacial stability of high-voltage LiCoO2 via fabricating a front-face with confined channels for desolvation.
Lithium cobalt oxide (LiCoO2, LCO) is one of the most successful cathodes. However, it suffers from severe structural degradation and rapid capacity fading at high voltage (>4.5 V vs. Li+/Li). To improve high-voltage stability, researchers employ channel-type materials to desolvate lithium ions, resulting in a localize...
