Back Cover : Article number 2100731 describes the fabrication of a micro‐supercapacitor on a printed circuit board. Volker Strauss, Alexander J. C. Kuehne, and co‐workers develop a laser‐carbonization process for polyacrylonitrile films, leading to patterned, interdigitated carbon electrodes. The unexposed, non‐carbonized areas of the film can be peeled‐off to fully expose the carbonized electrodes to an electrolyte. Specific capacities as high as 260 µF cm –2 can be achieved.
