Artificial Amorphous Interface Matters for Boosting High‐Voltage Stable LiCoO2 Cathode
Advanced Functional Materials, EarlyView.The amorphization of phosphate‐based surface layer with favorable Li‐ion conducting kinetics is realized by precisely tailored atomic‐level fabrication. This amorphous coating enables the lithium cobalt oxide (LCO) cathode superior high‐voltage rate capability and cycling performance, owing to the fast interfacial ionic transport and maintained ...
