Transport Properties of Flexible Composite Electrolytes Composed of Li_1.5Al_0.5Ti_1.5(PO₄)₃ and a Poly(vinylidene fluoride-co-hexafluoropropylene) Gel Containing a Highly Concentrated Li[N(SO₂CF₃)₂]/Sulfolane Electrolyte.

ABSTRACT: Flexible solid-state electrolyte membranes are beneficial for feasible construction of solid-state batteries. In this study, a flexible composite electrolyte was prepared by combining a Li⁺-ion-conducting solid electrolyte Li_1.5Al_0.5Ti_1.5(PO₄)₃ (LATP) and a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) gel containing a highly concentrated electrolyte of Li[N(SO₂CF₃)₂] (LiTFSA)/sulfolane using a solution casting method. We successfully demonstrated the operation of Li/LiCoO₂ cells with the composite electrolyte; however, the rate capability of the cell degraded with increasing LATP content. We investigated the Li-ion transport properties of the composite electro
