Electrode material, preparation method thereof and supercapacitor based thereof

摘要

The disclosure discloses electrode material, preparation methods thereof and supercapacitors based thereof. Raw material for preparing the electrode material include PVDF and an additive which can be reacted with the PVDF to generate conductive active substance, the amount of the PVDF is 50 to 99 mass percentage, and the amount of the additive is 1 to 50 mass percentage. A PVDF-based composite film can be prepared from the raw materials; and activating treatment is performed on the film by virtue of a physico-chemical process, so that PVDF can generate a conductive active substance, the contact resistance of the PVDF and the active substance is reduced, and the conductive active substance is distributed in the PVDF-based composite film more uniformly. Button and wound supercapacitor and flexible capacitor, which are prepared from the electrode material, are high in power density and energy density, long in cycle life.
