FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, namely to a method for manufacturing an accumulator battery with a non-aqueous electrolyte. Manufacturing method comprises assembling the battery unit using a positive electrode containing N-methyl-2-pyrrolidone, and a non-aqueous electrolytic solution containing an oxalate complex compound, the battery unit is assembled so that the following expression is satisfied: 0.000036≤B1/A1≤0.001048, where A1 (mln-1) represents the content of N-methyl-2-pyrrolidone per unit weight of the active substance layer of the positive electrode, and B1 (mol/kg) represents the content of the oxalate complex compound per unit weight of the active substance of the negative electrode.
EFFECT: technical result of the invention is increased battery life while maintaining the capacitive characteristics, even when using or storing the battery in a high-temperature environment.
