PURPOSE:To improve softness and ion conductivity of a polymer solid electrolyte by adding isoprene and/or butadiene to a polymer solid electrolyte containing an ionic salt, a compound is which the salt is soluble, and an acryloyl-type compound and reacting them. CONSTITUTION:Isoprene and/or butadiene is added to a polymer solid electrolyte containing an ionic salt e.g. lithium trifluoromethanesulfonate, propylene carbonate in which the ionic salt is soluble, and an acryloyl-type compound such as polyethylene oxide acrylate, etc. When ultraviolet-ray is radiated so as to carry out a reaction, a part of a crosslinked net-work frame is formed. In this case, isoprene or butadiene is a raw material for elastomer and compounds using them can have rubber elasticity and become soft. In this way, softness and ion conductivity of the polymer solid electrolyte are improved. |
