Highly entangled P(VDF-TrFE) solid-state electrolytes for enhanced performance of solid-state lithium batteries.

ABSTRACT: Solid polymer electrolytes (SPEs) offer a promising solution to the safety concerns of lithium metal batteries (LMBs). While poly(vinylidene fluoride) (PVDF)-based SPEs possess advantageous mechanical and thermal properties, their prevalent trans-gauche (TGTG) and TTTG conformations create tortuous ion pathways within chains, and insufficient chain entanglement leads to discontinuous transport between chains, fostering non-uniform current distribution and lithium dendrite growth. This work addresses both limitations by employing a novel poly(vinylidene fluoride-co-trifluoroethylene), P(VDF-TrFE) copolymer as the matrix of SPEs. By utilizing an ultrahigh molecular weight (2.37 × 10⁶ g mol^-1) P(VDF-TrFE) synthesized via suspension polymerizat
