Abstract 1,3‐Dioxolane (DOL) can undergo in‐situ polymerization in batteries to form solid‐state organic electrolyte PDOL. When applied NCM811||Li battery system, PDOL helps optimize the contact and interface stability between electrodes. This study explores effects of with PE separators coated Li1 .3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) on performance batteries. 2,2,2‐trifluoroethyl phosphite (DETFPi), was mixed DOL at a 1 : 35 mass ratio. Then, LiBF used initiate thereby obtained DETFPi‐PDOL after 24 h room temperature. The composite exhibits enhanced ion conductivity (1.59×10 −4 S cm −1 ), high lithium transference number (0.78), wide electrochemical window (4.53 V), critical current density (2.2 mA −2 ). Li||PDOL@LATP||Li shows extremely low overpotential (35 mV) constant stable cycle 500 1.0 . After cycles C, remaining capacity is 153.9 mAh g retention 82.1 % NCM811||PDOL@LATP||Li indicates that LATP coating surface separator plays an important role optimizing DETFPI‐PDOL are effective improving cycling stability, rate performance, state NCM811

Abstract Thin‐layer composite polymer electrolytes (CPEs) provide a safer alternative to flammable liquid for all‐solid‐state sodium metallic batteries (ASSMBs) prototyping. However, conventional CPE designs suffer from insufficient ionic conductivities, oxidation upon high‐voltage and uncontrolled dendrite growth. Herein, an interpenetrating approach by incorporating optimized amount of acrylamide (AM) monomers polymerized within polyethylene oxide (PEO) matrix is proposed. The amide groups tangled PEO/poly(acrylamide) (PAM) segments facilitate the NaTFSI salt dissociation through coordination between CO═Na + N─H/TFSI − interactions, meanwhile boosting Na conduction along ethylene chains. Integrated with bacterial cellulose scaffold mechanical reinforcement, membrane reconciles tensile strength, conductance transference number. Robotic‐arm controlled spray coating applies 4,4′‐(Hexafluoroisopropylidene)diphthalic anhydride (6FDA) 1,2‐dibromobenzene (1,2‐DBB) onto opposite sides PEO/PAM‐BC membrane. electron‐withdrawing 6FDA layer promotes NaF‐rich cathode interface 4.74 V tolerance, while electron‐accepting 1,2‐DBB creates NaBr‐rich that mitigates diffusion barrier. In ASSMB configuration, prototype demonstrates 85.4% capacity retention over 500 cycles at room‐temperature wide‐temperature‐range adaptability 0 80 °C. Transmission‐mode X‐ray diffraction reveals reversible lattice breathing paired cathode, which highlights synergistic stabilized interfaces across scales practical design.
