PURPOSE:To provide a macromolecular electrolyte of a high ion conductivity by removing a solvent A from a mixture liquid containing the solvent A which is compatible to polyvinyl butyral, a solvent B capable of dissolving an ion dissociation salt, and an ion dissociation salt through drying or through dipping in the solvent B containing an ion dissociating salt. CONSTITUTION:A solvent A is removed from a mixture liquid containing the solvent A which is compatible to polyvinyl butyral, a solvent B capable of dissolving an ion dissociation salt, and the ion dissociation salt through drying or through dipping in the solvent B containing an ion dissociating salt. Because the ion dissociation salt is dissociated in the solvent B and ions move in the solvent B, the salt shows a high ion conductivity. Preferable solvents capable of dissolving the ion dissociation salt are, for example, tetrahydrofuran and 2-methyltetrahydrofuran. Preferable ion dissociation salts are LiClO4, LiBF4, (n-C5H11)4NI. This provides a macromolecular electrolyte of a high ion conductivity. |
