Abstract

original image

Electrospun TiC nano-felt with fiber diameters of ≈ 130 nm can be conformally transformed into carbide-derived carbon (CDC) after heat treatment in chlorine, report Hao Fong, Yuri Gogotsi and co-workers. The TiC-CDC nano-felts have been studied as flexible and binder-free electrodes for supercapacitors, and the results have demonstrated a high gravimetric capacitance and a superior power handling capability compared to conventional activated carbon electrodes. on p. 423
