TYPES OF BATTERY
1. Primary Battery (or) Primary cells (or) Non-reversible Battery
In these cells, the electrode and the electrode reactions cannot
be reversed by passing an external electrical energy. The reactions occur only
once and after use they become dead. Therefore, they are not chargeable.
Examples
Dry cell, mercury cell.
2. Secondary Battery (or) Secondary cells (or) Reversible Battery
In these cells, the electrode reactions can be reversed by passing
an external electrical energy. Therefore, they can be recharged by
passing electric current and used again and again. These are also called Storage
cells (or) Accumulators.
Examples
Lead acid storage cell, Nickel-cadmium cell.
3. Flow battery (or) Fuel cells
In these cells, the reactants, products and electrolytes are
continuously passing through the cell. Here chemical energy gets converted into
electrical energy.
Example
Hydrogen-oxygen fuel cell.
