Lithium-ion batteries (LiBs) are extensively considered as one of the most promising energy storages devices for electric vehicles and portable electronics (e.g., mobiles and laptops). The electrolyte plays a vital role in LIBs, which could help connect the cathode and anode by providing some channels for ionic charge carriers. Compared with conventional liquid electrolytes and solid polymer electrolytes, gel polymer electrolytes (GPEs) pose low flammability, improved safety and comparable electrochemical performances. In our work, a gel type electrolyte was fabricated with 3-ethyl-3-oxetanemethanol (EOM) and a lithium salt (LiFSI) as catalyst. And then, the thermal stability and electrolyte properties of the GPEs were investigated and the most worthy of mention is the GPEs display a considerable ionic conductivity(δ) of 2.99×10-3 S cm-1 at 30 ℃ We hope these results could promote the developments of gel type electrolytes in LiBs.
