On‐Chip Direct Laser Writing of PAN‐Based Carbon Supercapacitor Electrodes.

On-Chip Direct Laser Writing of PAN-Based Carbon Supercapacitor Electrodes B Back Cover b : 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.
