ABSTRACT:
Polymeric solid electrolytes are formed by the present invention, namely, by incorporating a low molecular weight polyethylene glycol, a high molecular weight polyethylene oxide and an alkali metal or ammonium salt in a specific cinnamate ester compound, followed by a polymerization and crosslinking. The polymeric solid electrolytes have high ionic conductivity, high strength as a film, and good adhesion with electrodes. Therefore, they can be applied widely as ionics materials, e.g., for the total solidification of lithium batteries and plastic batteries and high capacity condensers and as electrolytes for electrochromic displays.
