Abstract
The invention relates to a current collector for a flexible solid super capacitor and a preparation method of current collector. The current collector for the flexible solid super capacitor comprises a carbon fiber sheet and electric conduction binder. The preparation method comprises the following steps: evenly dispersing silane coupling agent-modified carbon nanofiber, graphite and polymer into a solvent according to component ratio to prepare the electric conduction binder; plating a metal layer on the surface of the carbon fiber sheet by utilizing a vacuum film plating machine or a magnetron sputtering instrument; putting on an electrode; coating the electric conduction binder onto the carbon fiber sheet; performing laminated curing; and drying to obtain the current collector for the flexible solid super capacitor. In the current collector for the flexible solid super capacitor, on one hand, the carbon fiber provides an electric conduction channel, and on the other hand, the carbon fiber takes an enhancement action. The device safety is improved while the system resistance is reduced.
