The invention relates to a method for producing an electrochemical accumulator, characterized by the following steps: a) providing a non-conductive substrate; b) mounting a first conductor track made of conductive material on the substrate; c) mounting a porous dielectric with redox-active molecules in the form of points on the first conductor track; d) mounting a second conductor track orthogonally to the first conductor track, wherein the conductor tracks have an electrode function at the intersection point, between which the dielectric is arranged; e) mounting a passivation layer on the substrate, the first conductor track, the dielectric and the second conductive track, wherein the first and the second conductor tracks form an accumulator with the dielectrics arranged therebetween at the intersection point, in which the redox reaction of the redox-active molecules on the electrodes is activated by applying voltage to the conductor tracks for generating a bit. The invention also relates to different accumulators and to the uses thereof.
