Abstract:
A gel electrolyte composition, which comprises a reversible gelling agent, an irreversible gelling agent, an electrolyte salt and a solvent for the electrolyte salt, wherein said reversible gelling agent is a substance which forms a uniform solution of an electrolyte solution comprising the electrolyte salt and the solvent for the electrolyte salt at a first temperature region of from 40 to 70Â° C., and reversibly forms a gel composition when the uniform solution is cooled to room temperature, and said irreversible gelling agent is a substance which irreversibly gels an electrolyte solution comprising the electrolyte salt and the solvent for the electrolyte salt at a second temperature region of from higher than 70 to 100Â° C.
