The present invention provides an electrolyte composition that provides better charging/discharging performance when used in a cell than a conventional electrolyte composition. The present invention relates to an electrolyte composition containing an alkali metal salt, at least one polymer selected from the group consisting of a polyether polymer, a (meth)acrylic polymer, a nitrile polymer, and a fluoropolymer, and an ion dissociation accelerator. The composition has an alkali metal salt concentration of 1.8 mol/kg or higher.
