Abstract
A gel composition comprising a reversible gelling agent, an irreversible gelling agent, an electrolyte salt and a solvent for the electrolyte salt; a preparation process for the gel composition which comprises a first step of heating a gel mixture of a reversible gelling agent, an irreversible gelling agent, an electrolyte salt and a solvent for the electrolyte salt to a first temperature region at which the reversible gelling agent functions, to transform the gel into sol and molding the sol into a desired shape; and a second step of heating the sol to a second temperature region at which the irreversible gelling agent functions, to gel irreversibly; and a gel electrolyte composition comprising the above-described gel composition and a process for the preparation thereof. The gel composition can be handled as a solid electrolyte, can be adhered closely with the surface of an electrode and can be used as an electrochemical element in a desired shape.
