Alkaline batteries, also known as alkaline dry batteries, alkaline zinc manganese batteries, and alkaline manganese batteries, are the best performing varieties in the zinc manganese battery series. Suitable for high discharge capacity and long-term use. The internal resistance of batteries is low, resulting in a higher current generation compared to regular carbon batteries. These types of batteries, as they do not contain mercury, can be disposed of with household waste without the need for deliberate recycling. Alkaline batteries are successful high-capacity dry batteries and are also one of the batteries with cost-effective performance. Alkaline batteries use manganese dioxide as the positive electrode, zinc as the negative electrode, and potassium hydroxide as the electrolyte. Its characteristics are superior to those of carbon batteries, with a large capacitance. The chemical formula is: Zn+MnO2+H2O → Mn (OH) 2+ZnO. Alkaline batteries adopt the opposite electrode structure as ordinary batteries, increasing the relative area between the positive and negative electrodes. High conductivity potassium hydroxide solution is used to replace ammonium chloride and zinc chloride solutions, and the negative zinc is also changed from flake to granular, increasing the reaction surface area of the negative electrode. In addition, high-performance electrolytic manganese powder is used, which greatly improves the electrical performance. Generally, Alkaline batteries of the same model have a capacity and discharge time of 3-7 times that of regular batteries, with a greater difference in low-temperature performance. Alkaline batteries are more suitable for high current continuous discharge and electric fields that require high working voltage, especially for cameras, flash lights, razors, electric toys, CD players, high-power remote controls, wireless mice, keyboards, etc
