ORGANIC ELECTROLYTE BATTERY

摘要

PURPOSE:To prevent self discharge by using electrolyte comprising tetraalkyl ammonium salt serving as electrolyte and gamma-butyrolactone or a mixture of gamma- butyrolactone and propylene carbonate serving as solvent. CONSTITUTION:Solvent of electrolyte 4 is gamma-butyrolactone or a mixture of gamma- butyrolactone and propylene carbonate of a ratio of 10:0-2:8 by weight. Electrolyte dissolved in the solvent is tetraalkyl ammonium salt. The electrolyte and solvent are used after the completion of dehydration. The concentration of electrolyte in the electrolyte 4 is 0.1mol/l or more in order to reduce the internal resistance of a battery.
