Molecular Engineering of an Ether-Nitrile Constructs Robust Dual-interphases for Ultra-Stable 4.5 V Lithium Metal Batteries

Key Points

• The central aim is to engineer robust dual-interphases to stabilize both the cathode and anode in high-voltage lithium metal batteries.
• Developed ether-nitrile constructs for the electrolyte interface.
• Assessed stability of both cathode and anode interfaces under high-voltage conditions.
• Evaluated performance metrics such as degradation rates and safety risks.
• Enhanced stability of dual-interphases significantly reduced degradation rates.
• Safe operation at 4.5 V was achieved with the newly engineered electrolyte.
• Improved performance metrics were observed compared to conventional electrolytes.
