Title: ALKALINE DRY-CELL BATTERY
Abstract:
An alkaline dry-cell battery is provided with a positive electrode, a negative electrode, a separator arranged between the positive electrode and the negative electrode, and an electrolytic solution contained in the positive electrode, the negative electrode and the separator, wherein the electrolytic solution contains an alkaline aqueous solution. The negative electrode contains a zinc-containing negative electrode active material and an additive, and the additive contains at least one component selected from the group consisting of benzoic acid, phthalic acid, isophthalic acid and salts thereof. The amount of the negative electrode active material contained in the negative electrode is 176 to 221 parts by mass relative to 100 parts by mass of water contained in the electrolytic solution. The amount of the additives contained in the negative electrode is 0.1 to 1.0 part by mass relative to 100 parts by mass of the negative electrode active material.
