Abstract

A rechargeable battery includes an energy harvesting unit and an energy storage unit, wherein the rechargeable battery has a positive pole and a negative pole for coupling to an external electronic device. The energy harvesting unit is used for harvesting ionization energy. The energy storage unit is electrically connected to the energy harvesting unit and the positive pole and the negative pole of the rechargeable battery for receiving the ionization energy harvested by the energy harvesting unit. The ionization energy harvested by the energy harvesting unit is used for extending a battery life of the energy storage unit after the energy storage unit is charged by an external power source every time.
