Organic electrolyte battery

Abstract

Abstract PURPOSE:To increase thermostability by constituting with a positive electrode, a negative electrode comprising lithium or lithium alloy, and electrolyte solution, and using organic electrolyte solution prepared by adding morpholine as a stabilizer to a specified lithium salt of Lewis acid and organic solvent as the electrolyte solution. CONSTITUTION:Morpholine whose fourth positive is substituted with alkyl group having the carbon number of 1-4 is added as a stabilizer to electrolyte using lithium salt of Lewis acid indicated in the formula LiMFe as a solute. The morpholine having alkyl group of the carbon number of 1-4 has ether bond tertiary amine in its molecule shown in the formula and stabilizes electrolyte. The adding amount of 4-alkyl morpholine is preferable to be 0.2-2 times mol of the salt of Lewis acid and the amount of lithium salt of Lewis acid is usually 0.1-3mol/dm<3> in the electrolyte. Thereby, thermostability of electrolyte is increased and deterioration in performance during storage is retarded.
