PURPOSE:To obtain the novel title electrolyte capable of exhibiting high ion conductivity in the vicinity of ambient temperature and having excellent film forming properties by thermally polymerizing a specific monomer in the presence of a salt of a specific metal ion and carbonates and forming the resultant polymer into a high polymer matrix. CONSTITUTION:The aimed electrolyte obtained by thermally polymerizing a monomer expressed by formula I and/or formula II (R1 and R5 are H, alkyl, etc.; R2 and R4 are lower alkylene; R3 is H, alkenyl, etc.; L is coupling group of z valent; P and q are 1-30; z is >=2) in the presence of a salt (preferably Li salt of LiPF6, etc.) of metal ion belonging to at least periodic table Ia or IIa group and carbonates (preferably ethylene carbonate and propylene carbonate) and forming the resultant polymer into a high polymer matrix. Furthermore, heat polymerization are preferably carried out at 50-120 deg.C for 0.1-3hr using a heat polymerization initiator. |
