Batteries-Dry Cell (Manufacturing) is an industry that involves the production of primary batteries that are commonly used in electronic devices. These batteries are called dry cells because they do not contain liquid electrolytes. The manufacturing process involves the assembly of various components such as the cathode, anode, and separator. The cathode and anode are made of different materials such as zinc, carbon, and manganese dioxide. The separator is a thin layer that prevents the cathode and anode from touching each other. The dry cell battery is then sealed in a metal or plastic casing to protect it from damage.
