What are carbon-zinc batteries and zinc-air batteries?

Carbon-zinc batteries are also known as carbon-zinc dry batteries, carbon-based batteries, and carbon-based batteries. The outer shell is made of zinc. Can be used as a battery container, but also as the negative electrode of the battery. Carbon-zinc batteries are developed from liquid Leclanche batteries. The traditional or general type uses ammonium chloride as the electrolyte; the battery is usually a carbon-zinc battery that uses zinc chloride as the electrolyte, which is an improved version of the generally used cheap battery. The positive electrode of the battery is mainly composed of powdered manganese dioxide and carbon. The electrolyte is a paste solution formed by dissolving zinc chloride and ammonium chloride in water. Carbon-zinc battery is the cheapest primary battery, so it has become the first choice of many manufacturers, because these manufacturers often have to distribute batteries in the equipment they sell. Zinc-carbon batteries can be used in low-power devices such as remote controls, flashlights, toys, or transistor radios. The carbon mixed in the carbon rod of the positive electrode of this battery and the manganese dioxide is only responsible for drawing current, and does not participate in the reaction. The positive electrode actually participates in the reduction reaction and supplies positive electricity to the manganese in the manganese dioxide, so it is also called manganese zinc. Batteries, zinc-manganese batteries or zinc-manganese dioxide batteries are also referred to as manganese dry batteries. The voltage of the carbon-zinc battery is 1.5V. Zinc-air battery Zinc-air battery (Zinc-airbattery) is a kind of special structure. A zinc alloy is used for the negative electrode. The cathode material is oxygen in the air. It is generally kept sealed during storage, so there is basically no self-discharge. Also called zinc-oxygen battery, sometimes called zinc-air battery. Since the zinc-air battery contains a high concentration of electrolyte (potassium hydroxide is highly alkaline and corrosive), once leakage occurs, it will corrode the nearby parts of the battery, and this corrosion may be irreparable and fatal. Because there are holes in the battery, the storage time of the battery after activation is very short, so the zinc-air battery is more prone to battery leakage. When using a zinc-air battery, replace the exhausted battery in time, check the battery condition frequently, and remove the battery when not in use for a long time. The voltage of the zinc-air battery is 1.4V. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
