PURPOSE:To increase discharge voltage or charge voltage by making electrolytic solution to consist of single solvent out of or mixtures with 1-isopropyl-2,2- dimethyl-1,3-propylene carbonate. CONSTITUTION:In the case of the organo-electrolytic solution electric cell that uses electrolytic solution 4 composed at least one kind of organic solvent and at least one kind of solute, 1-isopropyl-2,2-dimethyl-1,3-propylene carbonate are employed as the organic solvent. With use made of these kinds of electrolytic solution 4, discharge voltage goes up in the electric cell that employs metal oxide, metal element-of-oxygen-family compound, fluorocarbon, or synthetic metal for the positive electrode material. Charge-discharge efficiency is also improved for the secondary electric cell. These facts are considered to be due to increase in wetness of the electrodes. |
