Eutectic-based polymer electrolytes have emerged as promising solid because of their ionic liquid-like properties, while modifications are essential to further increase conductivity at room temperature and solve compatibility with lithium anode. In this work, an in situ polymerized composite electrolyte is modified by the addition fluoroethylene carbonate (FEC) whose beneficial effect systematically investigated different contents. Poly(ethylene glycol) diacrylate (PEGDA), deep eutectic solvent (LiTFSI:N-methylacetamide = 1:3), alumina fiber work monomer, solvent, three-dimensional skeleton, respectively. adjusting FEC content, dramatically raised three times 8.93 × 10-4 S cm-1, a 4-fold lithium-ion transference number 0.405. Meanwhile, electrochemical window widened from 3.5 4.8 V. The also helps improving stability Li anode, which comes LiF-rich interphases formed interfaces. dynamics LiFePO4 significantly enhanced higher reversibility full cells, so that fast capacity decay inhibited specific 124.1 mAh g-1 obtained after 300 cycles 1 C. These results provide effective modification for electrolyte, will boost its development solid-state batteries.
