摘要

Studies were carried out on gel electrolytes based on PMMA and non-aqueous solution of lithium salt, LiClO_4 in the mixed solvent of propylene carbonate and ethylene carbonate (PC+EC). This paper reports the influences of polymer concentration and ratios of mixed solvent on the properties of gel electrolytes. The addition of polymer has increased the viscosity considerably without affecting the stable potential window, resulting in thermally stable gels. Result shows that addition of EC increases the conductivity by two order of magnitude as compared to that of PC alone. However conductivity decreases with addition of EC beyond 2:1 ratio of EC:PC. These gel electrolytes showed good room temperature conductivity in the order of 10~(-3) S/cm with high transmission in the visible region. This makes the gel a very promising electrolyte candidate for electrochromic device application.
