Dry Cell Battery
They have a rod at the center called cathodethat is made of carbon and surrounded by an electrolyte paste. Different chemicals can be made into this paste such as ammonium chloride and manganese dioixde. It also has two terminals one positive and one nagitive. When a 'load' is connected a chemical reaction occurs with 1.5 volts of electricity -
Power Loom
