The invention provides a physical battery, which comprises an energy storage unit arranged in the housing, and a positive electrode and a negative electrode extending from the housing and being exposed on the housing. The energy storage unit is a super capacitor, and a positive electrode and a negative electrode of the super capacitor are electrically connected to the positive electrode and the negative electrode of the battery, respectively. The super capacitor taken as the energy storage unit is adopted in the physical battery, so that only a physical reaction, no chemical reaction, is carried out in a charging and discharging process. The service life of the battery is prolonged, and the charging and discharging time is reduced.
