Why are alkaline batteries more durable?

Alkaline power battery is also called alkaline zinc-manganese dry battery. Compared with ordinary dry battery (carbon battery), it has the advantages of durability, large current, long storage life and corrosion resistance of the outer casing. The alkaline battery is structurally used in the opposite electrode structure of the ordinary battery, which increases the relative area between the positive and negative electrodes, and replaces the ammonium chloride and zinc chloride solution with a highly conductive potassium hydroxide solution, and the negative zinc is also used. It is changed from flake to granular, which increases the reaction area of the negative electrode. In addition, the high-performance electrolytic manganese powder is used, so the electrical performance is greatly improved. The alkaline battery of the same type is the capacity and discharge time of the ordinary battery 7 times. In addition, when the alkaline battery is discharged, no gas is generated inside, and the ordinary dry battery generates some gas when it is discharged, so the voltage of the alkaline battery is relatively stable. Alkaline batteries have few filler that do not participate in chemical reactions, so they can be made smaller. In this way, alkaline batteries of the same volume are more durable than carbon batteries.

Alkaline batteries are suitable for high-current continuous discharge and high-demand operating voltage applications, especially for cameras, flashlights, razors, electric toys, CD players, high-power remote controls, etc.
