A cell is an electrical energy source that uses chemical reactions to generate a current. An electrical cell is an ‘electrical power supply. It converts stored chemical energy into electrical potential energy, which can be used to provide electricity.
A cell acts as a ‘battery.’ The chemical reactions create the electromotive force that drives an electrical current from an external power supply down a conductor to provide useful electrical energy.
The conversion of chemical energy into electrical energy is therefore called electrochemistry. An electrical cell contains one or more electrodes connected and is used as a battery or power supply.
Cells (electrochemical cells) are made of electrodes, usually two, and electrolytes. For better electrical contact, many other conductive materials are used. These include glass, rubber, graphite, and various plastics.
The mechanical structure is usually clean paper or non-conducting plastic foam material insulators to separate the electrodes from their supporting structure (spacer) and ensure there is no short circuit between them.
