Abstract
Composite electrode/current collectors for capacitors, e.g., a flow-through capacitor or electric double layer capacitor are disclosed. Also disclosed are methods for making a composite electrode/current collectors and capacitors having at least one composite electrode/current collector.
Claims9
A method of making a capacitor comprising:
- a. mixing an effective amount of exfoliated graphite and electrode material to form a mixture having at least about 5 wt % of said exfoliated graphite, wherein, said electrode material comprises:
- 1) at least one material selected from the group consisting of:
- graphite, carbon nanotubes, activated carbon fibers, graphite fibers, carbon nanofibers, graphite nanofibers, carbon black, and activated carbon, and
- 2) a surface area of said electrode material comprises at least about 200 m2/g;
- b. compressing said mixture;
- and
- c. calendering said mixture.
