PURPOSE:To suppress the corrosion phenomenon of battery can material by adding lithium nitrate to electrolyte. CONSTITUTION:In a nonaqueous electrolyte battery, where fluorine-containing lithium salt is used particularly for a solute of a nonaqueous electrolyte, lithium nitrate is added to the electrolyte. By the arrangement, a passive state chromic oxide film is newly formed on stainless steel surface, which constitutes a battery can, by the oxidation effect of lithium nitrate, resulting in suppressed corrosion of the battery can material. |
