Abstract
Disclosed are (1) a thermopolymerizable composition containing a thermopolymerizable compound containing a (meth)acrylate having a moiety including oxyalkylene, fluorocarbon, oxyfluorocarbon and/or carbonate in the molecule, at least one electrolyte, and a polymerization initiator which is an organic peroxide containing no benzene ring, (2) a solid electrolyte obtained by thermally curing the composition, and (3) a primary battery, a secondary battery and electric double layer capacitor including the solid electrolyte, as well as a production method thereof. The polymer solid electrolyte obtained from the thermopolymerizable composition has high ion conductivity and good stability and the primary battery and secondary battery produced using the polymer solid electrolyte are operable at high capacity and high current, has a long-term service life and high reliability, and can be produced at low costs. Further the electric double layer capacitor is high in output voltage, and outputs a large amount of current, has high working ability, has a long-term service life and high reliability, and can be produced at low costs.
