A battery is such a device that is composed of electrochemical cells and helps in the conversion of stored chemical energy into another form that is electrical energy. There are many different types of batteries. One of them is a dry cell battery. A dry cell battery is typically composed of an electrolyte solution which is in the form of a paste and it is immobilized. Still, there is enough moisture present in it which lets the current flow.
This is one of the advancements in the field of electrochemical cells as the dry cells provide better portability and safety. A dry cell battery is generally made up of Zn-C. The container is made up of zinc and it acts as an anode. There is a rod in the center which is made up of carbon and acts as a cathode. The electrolyte is made up of NH4Cl paste and a pin made of brass is present in the center and it allows the conduction of electricity.
