• Nonflammable gel polymer electrolyte (SGPE) is developed by in situ polymerizing trifluoroethyl methacrylate (TFMA) monomers with flame-retardant triethyl phosphate (TEP) solvents and LiTFSI–LiDFOB dual lithium salts.

• Molecular polarity interaction between TEP and PTFMA mitigates interfacial reactions and changes the solvation of Li⁺.

• SGPE forms stable inorganic-rich solid electrolyte interface/cathode electrolyte interface layer, exhibiting well compatibility with Li anode and LiCoO₂-type high-voltage cathode.

不可燃凝胶聚合物电解质的分子级多尺度设计，为锂金属电池构建稳定的SEI/CEI

• 
  不易燃凝胶聚合物电解质（SGPE）是由甲基丙烯酸三氟乙酯（TFMA）单体与阻燃磷酸三乙酯（TEP）溶剂和LiTFSI-LiDFOB双锂盐原位聚合而成。

• 
  TEP 和 PTFMA 之间的分子极性相互作用减轻了界面反应并改变了 Li ⁺的溶剂化。

• 
  SGPE形成稳定的富含无机固体电解质界面/正极电解质界面层，与Li负极和LiCoO ₂型高压正极表现出良好的相容性。
