PROBLEM TO BE SOLVED: To provide an electrolyte of a cell that can achieve a cell property whose cycle property is good even in the case of using at high voltage and a non-aqueous secondary cell having a cell property whose cycle property is good even in the case of using at high voltage. SOLUTION: In the electrolyte for the cell of the invention constituted by dissolving a lithium salt being at least perfluoroalkyl sulfone acid derivation material into an organic solvent, it is characterized in that an organic solvent includes more than one kind of combination selected from heterocyclic combination including nitrogen or oxygen having more than one kind of fluorine atom. That is, for an oxidation of the positive pole collector causing a problem in the case where the lithium salt being the per fluoroalkyl sulfone acid derivation material is included into the electrolyte, it can form a membrane of a strong adsorption layer having resistance on a positive pole collector by including the heterocyclic combination including nitrogen or oxygen having the fluorine atom into the electrolyte for cell. |
