NOVELTY - The utility model claims capacitor technology field, and claims a graphene is disc substrate of super capacitor, comprising an aluminium shell, a sealing cover, a wiring terminal, a internal thread ring, external screw thread rod, a rotating wheel, a positive electrode foil guiding bars, negative electrode foil guiding bars, a protecting device, a positive electrode foil and negative electrode foil and a capacitor core; the top part of the sealing cover is connected with the connecting terminal of the bottom. The utility model solves the problem that the two poles of the circuit component in the capacitor insulating effect is bad, easy to breakdown short circuit, caused by high temperature cracking, even burning, even when power supply is cut off. the voltage stored in the capacitor is still present and the capacitor shell insulating effect is bad, if the user touches the capacitor is easy to generate danger of electric shock of human body; the shell of the capacitor material is aluminium material, impact is easy to deform, damage the capacitor, it is easy to cause capacitor short circuit. the problem caused by high temperature cracking, even burning.
