The invention provides an internally combined super capacitor which comprises an anode, a cathode, a diaphragm and electrolyte. The internally combined super capacitor is characterized in that the anode and the cathode are composed of active substances and perforated current collectors, the active substance of the anode is a mixture containing built-in lithium metal oxide and active carbon, and the active substance of the cathode is hard carbon. According to the internally combined super capacitor, through the energy storage potential matching technology of the anode and the cathode, the current collectors of the anode and the cathode respectively adopt perforated cathode foil and perforated copper foil, and electrochemical pre-doping of lithium ions is performed on the hard carbon of the cathode through a third electrode, so that the initial charged state of the hard carbon reaches 30% to 80%. According to such a finally obtained super capacitor battery, the characteristics of high specific power, long service life and quick charge of the super capacitor are kept, and the specific energy is greatly increased. Compared with a traditional lithium ion capacitor, the internally combined super capacitor has a great application prospect, and the characteristic of the super long cycle life is reserved. The working voltage of the internally combined super capacitor can reach 4.2 V, the specific energy can reach about 50 Wh/kg, the specific power can reach about 10, 000 W/kg, and the cycle life can reach 50, 000 times.
