GRAPHENE SUPERCAPACITOR AND MANUFACTURING METHOD THEREFOR

A graphene supercapacitor and a manufacturing method therefor. The graphene supercapacitor comprises: a capacitor body (101) comprising a plurality of individual capacitors (102) and an inner tab (103), wherein adjacent individual capacitors (102) in the plurality of individual capacitors (102) are connected in series or in parallel by means of the inner tab (103); two outer tabs (104); and an outer package (105). The manufacturing method for the graphene supercapacitor comprises: (1) fixing a polymer film substrate on a base material (S110); (2) irradiating the polymer film substrate with a CO2 infrared laser so as to obtain a patterned graphene positive electrode, a graphene negative electrode, and an inner tab (S120); (3) obtaining the graphene positive electrode, the graphene negative electrode, and the inner tab by cutting (S130); forming a plurality of individual capacitors by coating with electrolyte, wherein adjacent individual capacitors in the plurality of individual capacitors are connected by mean
