| abstract |
The invention concerns a solid polymer electrolyte characterized in that it comprises at least a methacrylonitrile polymer in the form: of a linear homopolymer with strong mass, reinforced or not; or a homopolymer, reinforced or not made three-dimensional by crosslinking; or a linear copolymer with strong mass or made three-dimensional by crosslinking, in particular by incorporation of at least a crosslinkable comonomer. The invention is useful for making electrochemical generators, high load capacitors or electrochrome systems. |
