Abstract
The present invention provides a gel electrolyte cell including a non-aqueous electrolytic solution containing lithium-containing electrolyte salt solved in a non-aqueous solvent and made into a gel state by a matrix polymer, and the gel electrolyte contains vinylene carbonate or derivative thereof in the amount not less than 0.05 wt % and not greater than 5 wt %. This gel electrolyte exhibits an excellent chemical stability with the negative electrode, strength, and liquid-retention characteristic. This gel electrolyte enables to obtain a gel electrolyte cell satisfying the cell capacity, cycle characteristic, load characteristic, and low-temperature characteristic.
