Gel polymer electrolytes with ionic liquid [BMIM]Cl-ZnCl_2 and an aprotic solvent were prepared via in situ free radical polymerization from vinyl monomers MA, MMA or HEMA as matrix and studied. The structure and properities of the products were studied by means of FTIR, AC, and TG. The interactions and structure changes of the composites were investigated by FTIR. The combination of a Lewis acid ionic liquid, [BMIM]Cl-ZnCl_2 with aprotic solvent PC or DMC strongly increased the ionic conductivity in comparison with the neat ionic liquid, which showed a highly ionic conductivity of up to 2.83×10~(-3) S/cm at room temperature. And the activation energies of ions were calculated according to VTF equation. The gel polymer electrolytes exhibited high decomposition temperatures of above 275 ℃.
