What are carbon batteries and alkaline batteries

The full name of carbon battery: neutral zinc-manganese dry battery (zinc-manganese dry battery), which belongs to the primary battery in chemical power supply, and is a kind of disposable battery. Because the electrolyte of this kind of chemical power device is a paste that cannot flow, it is also called a dry battery, which is related to a battery with a flowable electrolyte. Carbon batteries are not only suitable for flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, toys, etc., but also for various fields in the national economy such as national defense, scientific research, telecommunications, navigation, aviation, and medicine. Carbon batteries are mainly used in low-power appliances, such as clocks, wireless mice, etc., high-power appliances should use alkaline batteries, such as cameras, and some cameras can’t be alkaline, so use nickel-metal hydride. Alkaline batteries 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 large discharge capacity and long-term use. The internal resistance of the battery is lower, so the current generated is larger than that of ordinary carbon batteries. Because this type of battery does not contain mercury, it can be disposed of with domestic waste and does not need to be recycled. Alkaline batteries are successful high-capacity dry batteries, and they are also one of the batteries with a cost-performance ratio. Alkaline batteries use manganese dioxide as the positive electrode, zinc as the negative electrode, and potassium hydroxide as the electrolyte. Its characteristics are better than those of carbon batteries, and the electric capacity is large. The chemical formula is: Zn+MnO2+H2O→Mn(OH)2+ZnO. Alkaline batteries adopt the opposite electrode structure of general batteries in structure, which increases the relative area between the positive and negative electrodes, and replaces ammonium chloride and zinc chloride solutions with highly conductive potassium hydroxide solutions. The negative electrode zinc is also The change from flakes to granules increases the reaction area of u200bu200bthe negative electrode. In addition, high-performance electrolytic manganese powder is used, so the electrical performance is greatly improved. Generally, the same type of alkaline battery is the capacity and discharge time of a general battery 3-7 times higher than the low temperature performance. Alkaline batteries are more suitable for high-current continuous discharge and high working voltage applications, especially for cameras, flashlights, razors, electric toys, and CDs. Computer, high-power remote control, wireless mouse, keyboard, etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
