ABSTRACT:
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.
