Supercapacitors: Flexible, Planar‐Integrated, All‐Solid‐State Fiber Supercapacitors with an Enhanced Distributed‐Capacitance Effect (Small 11/2013)

G. Z. Shen and co-workers present a novel design for a flexible planar-integrated all-solid-state fiber supercapacitor, including several ZnCo2O4 nanowire arrays/carbon fiber composite wire electrodes, a transparent/bendable PET substrate, and two Ag electrodes. The as-fabricated flexible device exhibits high efficiency, a long cycle life, and excellent electrical stability. The strategy presented on page 1998 enables highly flexible future supercapacitors with maximum functionality and minimized size, which may meet many potential applications such as wearable/stretchable displays, cardiac pacemakers, electronic paper, etc.
