The invention discloses a laser-induced MnO2 and graphene micro-supercapacitor and a manufacturing method; the method comprises: soaking a polyimide film required for preparing a micro-supercapacitor in a manganese chloride solution; The polyimide film is bonded to the rigid substrate, the bonded substrate is dried, and the dried polyimide film is obtained by separating from the dried bonded substrate; The electrode pattern of the micro super capacitor is induced on the good polyimide film to obtain a capacitor electrode; the material of the capacitor electrode includes MnO 2 and graphene; a solid electrolyte is prepared based on the capacitor electrode, and the prepared micro super capacitor is obtained. capacitor. The invention can improve the energy storage performance of the electrode material of the micro super capacitor, and has the advantages of simple process, high patterning efficiency and strong substrate selectivity, and has the prospect of large-scale integrated mass production. |
