Elastic and sticky polymer gel electrolytes were prepared by polymerisation of methacrylate resin to which solutions, containing LiBF4 and [(C2H5)(4)N]BF4 in various ratios in PC, were added, keeping the ionic strength constant. A concentration cell containing two polymer samples and two equal LiHgx electrodes was used for the estimation of reversible potential. At RT, their conductivity was not much depressed by the presence of the polymer gel and it was of ohmic nature. Below -40 to -30 degrees C, the behaviour of a high tg delta dielectric was observed and the conductivity decreased rapidly.
