PURPOSE:To enhance the high temp. preserving performance to a great extent by using as electrolyte an organic solvent solution of tetraalkyl ammonium salt including a methyl radical as either of the alkyl radicals. CONSTITUTION:A coin type organic electrolyte battery includes an organic electrolyte which is an organic solvent solution of tetraalkyl ammonium salt as expressed by the chemical equation given beside the text. Either of R1-R4 in the equation should be methyl radical while the other three are ethyl radical, and X represents a negative ion residual radical of the tetraalkyl ammonium salt. As the electrolyte, a 1-mol/l solution of CH3(C2H5)3NBF4-propylene carbonate is used, and with this the electrode is impregnated. This allows suppressing increase of the internal resistance even under high temp. preservation. |
