Patent number: 5326657Abstract: The invention provides a specific polymeric solid electrolyte (ionically conductive polymer) having excellent physical properties, and a process therefor. The polymeric solid electrolyte can be obtained by reacting an alkali metal salt and/or ammonium salt, a non-aqueous organic solvent, a polyfunctional acrylate compound and a particular polyether macromonomer in the presence of a radical polymerization initiation accelerator and a radical polymerization initiator.The polymeric solid electrolyte has high ionic conductivity so that it can be employed in useful lithium batteries, plastic batteries, large-capacity capacitors, electrochromic displays and it can also be used for the 100% solidification of other electronic devices.Type: GrantFiled: July 24, 1992Date of Patent: July 5, 1994Assignee: Nippon Oil Co., Ltd.Inventors: Masanobu Suga, Seiichi Akita, Nobuyuki Kuroda
