The present invention relates to a supercapacitor comprising an electrode pad and a diaphragm, the electrode pad comprising a plug pole segment extending into the capacitor, one end of the plug pole segment is provided with a fixed pole segment, and one end of the fixed pole segment is provided with Locking the pole segment, one end of the locking pole segment is provided with an outer connecting pole segment, and the plug pole segment and the fixed pole segment are integrally formed in an "L"-shaped folded plate shape, and the locking pole segment as a whole is " U-shaped, the above-mentioned plug-in pole piece is inserted into the capacitor. The iron oxide formed on the electrode sheet is uniformly distributed between the graphene oxides, and the agglomeration of the graphene oxide is effectively avoided. By the action of an external magnetic field, the iron oxide is always in a paramagnetic vertical state, forming a tiny iron needle, which helps the graphene oxide coating to form a needle-like microstructure surface. This structure has super-lipophilic properties and can be in closer contact with the organic phase electrolyte than the general structure, allowing the specific surface area provided by the material to be fully utilized. |
