Abstract
The present disclosure provides an electrolyte composition including a polymer having an ability to conduct alkali metal ions and an organic solvent, wherein an overall donor number represented by the following formula (I) of the organic solvent included in the electrolyte composition is 16.5 or more. [ Formula 1 ] DN = ∑ i = 1 n ( DNi ) × ( fi ) ( 1 ) (wherein n is a total number of organic solvents included in the electrolyte composition and is 1 or more, DNi is a donor number of an i-th organic solvent, and fi is a mass fraction of the i-th organic solvent).
