Poly(vinylidene fluoride) (PVDF)-based solid polymer electrolytes (SPEs) with “lithium salt in polymer” configurations typically exhibit poor lithium salt dissociation and mechanical strength. In this study, we proposed a composite polymer electrolyte (CPE) for solid-state lithium-ion batteries (LIBs) as a novel approach to address the challenges. The CPE incorporates a high dielectric polymer poly(vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene) (P(VDF-TrFE-CTFE)) as the polymer matrix, and sodium super ionic conductor (NASICON)-type ceramic Li1.5Al0.5Ti1.5(PO4)3 (LATP) as fillers. The optimized CPE demonstrates enhanced dissociation of lithium salts, leading to high ionic conductivity (1.1 mS·cm−1) and improved lithium transference numbers (
