Trimethyl phosphate (TMP) is a promising alternative for flammable carbonate electrolyte solvents owing to its nonflammable nature. But the low-concentration TMP-based electrolyte is unstable with the lithium metal anode. Here, a TMP-contained quasi-solid electrolyte (PIQSE) with porous polyimide (PI) as supporting skeleton is designed. The cross-linking structure generated by UV curing in PIQSE can lock the reactive TMP solvent to reduce its contact with Li metal. Besides, the PI supporting skeleton with high-temperature resistance can significantly enhance the thermal stability of PIQSE. The combination of PI and TMP prompts the high ionic conductivity and excellent nonflammability of PIQSE.
