Difference Between Cell and Battery

The cell and battery both store the chemical energy and then transforms the stored chemical energy into an electrical energy. One of the major difference between the cell and the battery is that the cell is the single unit, whereas the battery is the group of cells. Some other differences between them are explained below in the comparison chart.

 Definition of Cell

The cell is a single power generating unit which stores the chemical energy and then converts it into electrical energy. It has two electrodes namely cathode and the anode.The cell has an electrolyte, a chemical substance that reacts with the electrodes and produces electric current.

The redox reaction occurs between the electrolyte and the electrodes and due to this reaction the electric current starts flowing through an external circuit. The cell is mainly classified into four types.They are the wet cell, dry cell, reserve cell and fuel cell.The wet cell uses a liquid electrolyte, and in the dry cell, the electrolyte is in the form of the powder.

Definition of Battery

The battery is a device which consists two or more units of an electrochemical cell.The positive terminal of the battery is known as the cathode whereas the negative terminal of the battery is known as the anode. The battery is of two types, i.e., the primary battery and the secondary battery.

The primary battery is irreversible or cannot be reused, whereas the secondary battery is rechargeable. In a primary cell, the chemical energy is inherently present, and in the secondary cell, the electrical energy is induced by the external source.

The galvanic cell, Daniel cell, Leclanche cell are some of the examples of the cell while lead-acid battery, lithium-ion battery, magnesium ion battery, etc. are the types of the battery.
