摘要： The invention provides an electrolyte solution that is for an alkali metal-sulfur-based secondary battery, that requires no addition of lithium polysulfides, and that has excellent cycle performance and a low resistance during charge and discharge, and an alkali metal-sulfur-based secondary battery. The electrolyte solution is for an alkali metal-sulfur-based secondary battery that includes a positive electrode containing a carbon composite material that contains a carbon material and a sulfur-containing positive electrode active material. The carbon material has a pore volume ratio (micropores/mesopores) of 1.5 or higher. The electrolyte solution contains a fluorinated ether represented by the following formula (1): R 11 -(OR 12 ) n11 -O-R 13 . In the formula, R 11 and R 13 are the same as or different from each other, and are each an alkyl group optionally containing a fluorine atom, with at least one of R 11 or R 13 containing a fluorine atom; R 12 is an alkylene group optionally containing a fluorine atom; and n11 is 0, 1, or 2.
