Rechargeable Li-ion batteries (LiBs) have acted as an essential part in our daily lives, ranging from portable consumer electronic devices to large-scale transport equipment like electric vehicles. For overcoming interfacial drawbacks and enhancing polymer electrolyte safety, in-situ polymerization is considered one of most promising approaches for enabling interfacial issues between electrolyte and electrodes. Herein, we observed the in-situ thermal induced electrolytes based on epoxy-group with LiFSI as an initiator, and a varies of technologies were applied into investigating structure characters, physicochemical properties, and electrochemical performances of as prepared solid-state polymer electrolytes. The proton nuclear magnetic resonance (1H-NMR) and Fourier transform infrared (FTIR) revealed the polymerization was successful. The conductivity of as-prepared electrolyte could over 1 mS/cm at 30 ℃. Moreover, the obtained electrolyte also exhibited good batteries performance.
