WebA potato battery is a type of battery that is known as an electrochemical cell. The chemicals zinc and copper (in the screw and penny/wire) react with each other, which produces chemical energy. This chemical energy is converted to electric energy by a spontaneous electron transfer. The potato acts as a buffer and an electrolyte for the two metals. WebFeb 24, 2012 · Construction of Alkaline Battery. The body of the battery is made of a hollow steel drum. This drum contains all materials of the battery, and it also serves as the cathode of the battery. The positive terminal of the battery is projected from the top of this drum.
