1. A cell is made up of three parts, a cathode, an anode and an electrolyte (a chemical).
2. A cell works by connecting its stored chemical energy, into electrical power
3. One the electrolyte of the cell is used up it doesn’t work further in non – rechargeable cells (Alkaline cells).
4. Electrons (negative charges) travel from an anode to a cathode until the anode is considered empty or dead.
5. A rechargeable cell, a charger can reverse the electron flow again to restore at the anode. This is called charging.
6. This reversing process depends upon the electrolyte used in the cell.
7. Normal cells do not contain such type of electrolytes to reverse the charge.
8. But, the cells like NiMH (Nickel – Metal Hydride), Lithium – ion are capable of reversing the charge when charged it for number of times.
9. This type of rechargeable batteries are used in rechargeable torch lights, bulbs, mobile phones and fans.
