摘要

A cell wherein use is made of a solid electrolyte prepared by dissolving a trifunctional acryloyl-terminated alkylene oxide polymer having a polymer chain represented by general formula (1) and an electrolyte salt in 220-950 wt.%, based on the polymer, of a solvent, and cross-linking the polymer by applying an active radiation and/or heat, wherein R' represents C1-C6 alkyl; R'' represents hydrogen or methyl; and m and n represent each a number of 0, 1 or above, provided that m + n >/= 35. A typical cell is one composed of a composite positive electrode comprising a solid electrolyte integrated with a positive electrode active material, prepared by mixing the above polymer with an electrolyte salt, a solvent and a positive electrode active material and cross-linking the polymer by applying an active radiation and/or heat to the formed mixture, and, provided between the positive electrode and a negative electrode, a separator comprising a solid electrolyte layer prepared by mixing the above polymer with an electrolyte salt and a solvent and cross-linking the polymer by applying an active radiation and/or heat to the formed mixture.
