It is urgent to seek high performance solid polymer electrolytes (SPEs) via a facile chemistry and simple process. The lithium salts are composed of complex anions that are stabilized by a Lewis acid agent. This Lewis acid can initiate the ring opening polymerization. Herein, a self‐catalyzed strategy toward facile synthesis of crosslinked poly(ethylene glycol) diglycidyl ether‐based solid polymer electrolyte (C‐PEGDE) is presented. It is manifested that the poly(ethylene glycol) diglycidyl ether‐based solid polymer electrolyte possesses a superior electrochemical stability window up to 4.5 V versus Li/Li+ and considerable ionic conductivity of 8.9 × 10−5 S cm−1 at ambient temperature. Moreover, the LiFePO4/C‐PEGDE/Li batteries deliver stable charge/discharge profiles and considerable rate capability. It is demonstrated that this self‐catalyzed strategy can be a very effective approach for high performance solid polymer electrolytes.

用于可充电电池的高性能固体聚合物电解质：一种易于合成的自催化策略
迫切需要通过简单的化学过程和简单的工艺来寻求高性能的固体聚合物电解质（SPE）。锂盐由通过路易斯酸剂稳定的复合阴离子组成。该路易斯酸可以引发开环聚合。在此，提出了一种轻松合成交联聚乙二醇二缩水甘油醚基固体聚合物电解质（C-PEGDE）的自催化策略。结果表明，聚乙二醇二缩水甘油醚基固体聚合物电解质相对于Li/Li +具有高达4.5 V的优异电化学稳定性窗口，并且在环境温度下具有8.9 × 10 -5 S cm -1的相当大的离子电导率。此外，LiFePO 4 /C-PEGDE/Li 电池具有稳定的充电/放电曲线和相当大的倍率能力。事实证明，这种自催化策略可以成为高性能固体聚合物电解质的一种非常有效的方法。
