Capacitors: Flexible Films Derived from Electrospun Carbon Nanofibers Incorporated with Co₃O₄ Hollow Nanoparticles as Self‐Supported Electrodes for Electrochemical Capacitors (Adv. Funct. Mater. 31/2013)

On page 3909, X. G. Zhang, X. W. Lou, and co-workers derive flexible porous films from electrospun carbon nanofibers incorporating Co3O4 hollow nanoparticles as advanced self-supported hybrid film electrodes for electrochemical capacitors. Such unique film electrodes exhibit very high specific capacitance and excellent electrochemical stability at high current densities. These features make them attractive for flexible power sources.
