A gel electrolyte comprised of a non-aqueous electrolytic solution immersed in a matrix polymer, in which ion conductivity of a solvent is improved and superior cyclic characteristics are achieved. To this end, the gel electrolyte includes an electrolyte, a matrix polymer and a non-aqueous solvent. The non-aqueous solvent is a mixed solvent of ethylene carbonate (EC), propylene carbonate (PC) and gamma -butyrolactone (GBL). The non-aqueous solvent is of a weight composition in an area in a triangular phase diagram (EC, PC, GBL) surrounded by a point (70, 30, 0), a point (55, 15, 30), a point (15, 55, 30) and a point (30, 70, 0). A gel electrolyte battery employing this electrolyte is also disclosed. <IMAGE> |
