ORGANIC ELECTROLYTE BATTERY

摘要

PURPOSE:To prevent voltage drop of a battery in high discharge rate by using at least 2-methyltetrahydrofuran-3,5-dione as one solvent of an organic electrolyte. CONSTITUTION:At least 2-methyltetrahydrofuran-3,5-dione is used as one solvent of an organic electrolyte. By modifying 2-methyltetrahydrofuran so as to have carbonyl groups in positions 3, 5 of 2-methyltetrahydrofuran in the formula I, dielectric constant is increased. Performance of a battery is increased.
