With the increasing crisis of energy and environment issues, a number of new energy storage devices have grasped the attention worldwide, among which electrochemical capacitor or supercapacitor (SC) is considered to be a promising domain.Supercapacitors are well-known for the high power density, therefore, to improve the conductivity of the active material and the contact of the active material to the current collector are important to better put up the performance of the SC.The commonly used current collectors of SC are metal foil or metal mesh, in spite of their excellent conductivity, the contact to the active material is still in need of improvement.
