Manipulating Interfacial Stability via Preferential Absorption for Highly Stable and Safe 4.6 V LiCoO2 Cathode
Highlights A novel electrolyte design strategy for high voltage and high safe LiCoO2 (LCO) cathode based on highest occupied molecular orbital and LCO absorption energy descriptor was proposed. The irreversible phase transformation was restricted by the LiF rich LCO/electrolyte interface. The well d...

| description | Highlights A novel electrolyte design strategy for high voltage and high safe LiCoO2 (LCO) cathode based on highest occupied molecular orbital and LCO absorption energy descriptor was proposed. The irreversible phase transformation was restricted by the LiF rich LCO/electrolyte interface. The well designed tris 2, 2, 2-trifluoroethyl phosphate electrolyte endows Ah grade Gr||LCO pouch cell with excellent electrochemical performance (85.3% capacity retention after 700 cycles), low-temperature adaptability (−60 °C retention: 53%) and greatly improved thermal safety (pass nail penetration). |
