Abstract
(EN)
The present invention provides an electrolyte composition which exhibits more excellent charge/discharge performance than conventional electrolyte compositions if used in a battery. The present invention is an electrolyte composition which contains an alkali metal salt; and this electrolyte composition is characterized by comprising an ion dissociation accelerator and at least one polymer selected from the group consisting of polyether-based polymers, (meth)acrylic polymers, nitrile-based polymers and fluorine-based polymers, while being also characterized in that the concentration of the alkali metal salt is 1.8 mol/kg or more.
