The document summarizes the manufacturing process of zinc-carbon dry cells. Key raw materials include zinc cans, manganese dioxide, carbon rods, and an electrolyte solution containing zinc chloride and mercury. The cathode mixture is produced by mixing manganese dioxide and acetylene black, then adding the electrolyte solution. The cell is assembled by inserting a separator, filling the cathode material, adding the carbon rod and sealing the can. A plastic gasket and negative terminal are fitted, then a positive terminal and metal jacket are added before final inspection. Strict safety and environmental practices are followed in manufacturing due to the hazardous materials.
