- •
Electron-insulating/ion-conducting Li3PO4 (LPO) is used to coat LiCoO2 electrodes.
- •
Amorphous LPO layer is coated by a facial magnetron sputtering approach.
- •
High-voltage (4.5 V) and high-temperature (50 °C) cell performances are studied.
- •
LPO-coated LiCoO2 electrodes exhibit improved cycling and rate performances.
- •
High-temperature performance improvements are more dominant after LPO coating.
