PROBLEM TO BE SOLVED: To provide an organic electrolyte secondary battery with low deterioration in load characteristics attendant on increase in charge/discharge cycles. SOLUTION: In an organic electrolyte secondary battery having a positive electrode 1, a negative electrode 2, and an organic electrolyte 4 as the main constituting element, a fluorine-containing polymer ether compound is contained in the organic electrolyte 4. As the fluorine-containing polymer ether compound, for example, CH3 [OCH(CF3 )CH2 ]4 OCH3 and CH3 [OCH(CF3 )CH2 ]6 OCH3 are preferable, and the content of the fluorine-containing polymer ether compound is preferable to be 0.1-10 pts.wt. based on 100 pts.wt. electrolyte solvent. |
