On page 5091 Prof. Jun Zhou, Prof. Kaifu Huo, and co‐workers demonstrate high‐performance all‐solid‐state supercapacitors based on flexible, free‐standing mesoporous vanadium nitride nanowire (MVNN)/carbon nanotube hybrid electrodes. The MVNNs are synthesized by way of a hydrothermal synthesis followed by thermal nitridation under an ammonia atmosphere. The devices show a stable performance and high volumetric capacitance, along with high volume energy and power density. These electrodes have potential applications in portable/wearable electronics.
