Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an alkaline battery. Background technique [0002] With the development of society and the advancement of science and technology, electronic products have been widely used, and people's requirements for power supply components of electronic products are also increasing. Alkaline batteries are also known as alkaline dry batteries, alkaline zinc-manganese batteries, and alkaline-manganese batteries. They are the varieties with superior performance in the series of zinc-manganese batteries. Generally, the same type of alkaline battery is 3-7 times the capacity and discharge time of ordinary batteries, and the gap between the two is even greater in low-temperature performance. Alkaline batteries are more suitable for high-current continuous discharge and high working voltage. Occasions, especially suitable for cameras, flash lights, shavers, electric toys, CD players, high-power r...
