High-Performance Flame-Retardant Polyphosphate ester-based Solid Electrolyte via In-situ Ring-Opening Polymerization for Safe Li Metal Batteries

Conventional flammable liquid electrolytes compromise the safety of lithium metal batteries. We address this via the molecular design and in-situ catalyst-free ring-opening polymerization of a trifluoromethyl-functionalized polyphosphoester, yielding a cross-linked...
