The Primary Batteries-Dry & Wet (Manufacturing) industry involves the production of primary batteries, which are non-rechargeable batteries that convert chemical energy into electrical energy. These batteries are commonly used in a variety of devices, including remote controls, flashlights, and toys. The manufacturing process for primary batteries involves the assembly of cells, which consist of an anode, a cathode, and an electrolyte. The anode and cathode are typically made of different metals, and the electrolyte is a solution that allows for the flow of ions between the anode and cathode. The cells are then packaged into batteries, which are often sold to consumers in retail stores.
