Abstract Solvent‐free manufacturing is crucial for fabricating high‐performance sulfide‐electrolyte‐based all‐solid‐state lithium batteries (ASSLBs), with advantages including side reaction inhibition, less contamination, and practical scalability. However, the fabricated sulfide electrolytes commonly suffer from brittleness, limited ion transport, unsatisfactory interfacial stability due to uncontrolled dispersion of particles within polymer binder matrix. Herein, a “solid‐to‐liquid” phase transition strategy reported fabricate flexible Li 6 PS 5 Cl (LPSCl) electrolytes. The polycaprolactone (PCL)‐based (PLI) phase‐transition characteristics fills gap LPSCl tightly grafts on particle surface via ion‐dipole interaction, bringing thin compact electrolyte membrane (80 µm). simultaneously high Li‐ion conducting electron insulating nature PLI facilitates transport ensures good between anode. Consequently, exhibits ionic conductivity (8.5 × 10 −4 S cm −1 ), enabling symmetric full cells 2.5 times longer cycling life compared that pristine electrolyte, respectively. demonstrated versatile can be extended ethylene vinyl acetate copolymer (EVA) also brings enhanced electrochemical performance. potentially dendrite‐free ASSLBs energy density.
