Is the battery leakage harmful?

Electronic products that use dry batteries generally have a reminder. When the appliance is not used for a long time, the battery should be removed. The usual explanation is: Dry batteries are chemical batteries. When the battery is almost exhausted, sometimes some electrolyte will flow out of the battery. This electrolyte will corrode the battery rack of the appliance and even flow to the circuit board to further corrode the circuit and cause damage to the appliance. When the appliance is stored for a long time and not in use, the user does not know that there is outflow. So is battery leakage harmful? Let's analyze the Baibai Safety Net for everyone. In our daily life, many battery leakages we encounter do not occur when the battery is almost exhausted or when the battery is out of shelf life. A fully charged battery suddenly leaks. The leaking electrolyte sometimes causes complete damage to the appliance. If the electrolyte contacts the skin, if it is not cleaned quickly, it may also cause chemical burns to the skin. All these happen without precautions. The dry batteries of Nanfu and other brands that we buy in stores are usually alkaline dry batteries, using manganese dioxide as the positive electrode, zinc as the negative electrode, and potassium hydroxide as the electrolyte. The chemical formula is: Zn+MnO2+H2O→Mn(OH)2+ZnO. It can be seen that there are a large amount of potassium hydroxide and a small amount of Mn(OH)2 dissolved in the electrolyte in the electrolyte of the battery. Potassium hydroxide: It is analytical in middle school chemistry. It is extremely alkaline and corrosive, and its properties are similar to that of caustic soda. It has a cauterizing effect on tissues. If the solution is splashed on the skin, especially the mucous membranes, soft scabs may appear. Splashing into the eye can not only damage the cornea, but also damage the deep tissues of the eye. Strongly irritate the respiratory tract or cause burns after inhalation. Direct contact with skin and eyes can cause burns; oral burns can cause death to the digestive tract. It can be seen that the damage of battery leakage is not only corrosive to electrical appliances, but also very harmful to people. So why are alkaline batteries leaking frequently, heavy metals or their compounds? Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
