A kind of gel polymer electrolyte was prepared by in situ polymerization of methyl methacrylate (MMA) monomers in room temperature ionic liquid (RTIL), N ‐butyl‐ N ′‐methylimidazolium hexafluorophosphate (BMIPF 6 ). In comparison with other gel polymer electrolytes, it reveals excellent thermal stability over 260°C. The results of differential scanning calorimetry (DSC) measurements show that its glass transition temperature decreases with an increase in the ratio of RTIL to polymer matrix. At 25°C, the gel polymer electrolyte has 0.15 × 10 −3 S cm −1 of ionic conductivity when the mass ratio of BMIPF 6 to MMA monomers equals 1. Analysis of FT‐IR spectra suggests that there exists a hydrogen‐bonded interaction between BMIPF 6 and poly(methyl methacrylate) (PMMA) polymer matrix in the polymer electrolyte.
