Dual-Component Coating Enables Stable 4.6 V Cycling of High-Voltage LiCoO2 Cathodes

Abstract Lithium cobalt oxide (LCO) cathode materials are widely used in 3C electronic products but suffer from rapid capacity fading at high voltages (>4.2 V). We propose a synergistic LiF/ZrO2 double-coating strategy to construct a flexible-rigid intimately intermingled nano-mo...
