The invention claimed is: 1. An electrode for a combination of supercapacitor and battery, comprising an active structure, wherein the active structure comprises an active material layer which is divided stripwise in a plane, with capacitor strips and battery strips being arranged alternately in the plane so that a pair of the battery strips are disposed on opposing sides of at least one of the capacitor strips and a pair of the capacitor strips are disposed on opposing sides of at least one of the battery strips. 2. The electrode according to claim 1 , wherein the active structure comprises three layers, with a first graphite layer, the active material layer and a second graphite layer being arranged in this order. 3. The electrode according to claim 2 , wherein the active material layer is free of binders. 4. The electrode according to claim 2 , wherein at least one of the first graphite layer and the second graphite layer comprises a conductive material as additive. 5. The electrode according to claim 1 , wherein a proportion of graphite and/or of a binder is lowest in a middle of the active material layer and increases in a direction of two surfaces of the electrode. 6. The electrode according to claim 1 , wherein a proportion of graphite is highest in a middle of the active material layer and decreases in a direction of two surfaces of the electrode. 7. The electrode according to claim 1 , wherein the electrode further comprises a power outlet foil on which the active structure is arranged. 8. A combined supercapacitor and battery cell comprising at least one electrode according to claim 1 . 9. The electrode according to claim 1 , wherein the plurality of capacitor strips and the plurality of battery strips being arranged alternately in the plane include at least three of the battery strips being arranged alternately in the plane with at least three of the capacitor strips so that at least two of the battery strips are disposed on opposing sides by adjacent ones of the capacitor strips that are in contact therewith and at least two of the capacitor strips are disposed on opposing side by adjacent ones of the battery strips that are in contact therewith. 10. The electrode according to claim 1 , wherein the pair of the battery strips are in contact with the opposing sides of at least one of the capacitor strips and the pair of the capacitor strips are disposed in contact with the opposing sides of at least one of the battery strips. 11. A process to produce an electrode having an active structure that includes an active material layer divided stripwise in a plane, with capacitor strips and battery strips arranged alternately in the plane so that a pair of the battery strips are disposed on opposing sides of at least one of the capacitor strips and a pair of the capacitor strips are disposed on opposing sides of at least one of the battery strips for a combination of supercapacitor and battery, including introducing starting materials for the active structure together into a pressing apparatus and pressing without addition of solvents to form a sheet, with the starting materials being introduced spatially distributed into the pressing apparatus by a plurality of application systems. 12. A process to produce an electrode having an active structure that includes an active material layer divided stripwise in a plane, with capacitor strips and battery strips arranged alternately in the plane so that a pair of the battery strips are disposed on opposing sides of at least one of the capacitor strips and a pair of the capacitor strips are disposed on opposing sides of at least one of the battery strips for a combination of supercapacitor and battery, including firstly applying starting materials for the active structure to a support or to a power outlet foil without addition of solvents by a plurality of application systems in one or more steps, and subsequently pressing the starting materials for the active structure applied to the support or to the power outlet foil in a pressing apparatus to form a sheet.
