Designing phosphazene-derivative electrolyte matrices to enable high-voltage lithium metal batteries for extreme working conditions

The current high-energy lithium metal batteries are limited by their safety and lifespan owing to the lack of suitable electrolyte solutions. Here we report a synergy of fluorinated co-solvent and gelation treatment by a butenoxycyclotriphosphazene (BCPN) monomer, which facilitates the use of ether-...
