Abstract
An ultracapacitor is manufactured from a woven carbon fiber material that is partially saturated with structural resin. The portion of the carbon fiber material that contains the resin may be used as a structural element in spacecraft or other applications. The carbon fibers of the woven material are used both as the current collector and the electrode. Activated carbon fiber material may be used or only the electrode portion of the carbon fibers may be activated.
Claims33
A method for manufacturing an electrode comprising:
- providing a woven carbon fiber fabric;
- saturating a portion of the thickness of said fabric to produce a saturated portion and an unsaturated portion, said saturated portion having at least some structural rigidity and said unsaturated portion having at least some exposed fibers;
- and
- attaching an electrical conductor to said saturated portion.
A method for manufacturing an ultracapacitor comprising:
- providing a first woven carbon fiber fabric;
- providing a second woven carbon fiber fabric;
- saturating a portion of the thickness of said first fabric to produce a saturated portion and an unsaturated portion, said saturated portion having at least some structural rigidity and said unsaturated portion having at least some exposed fibers;
- saturating a portion of the thickness of said second fabric to produce a saturated portion and an unsaturated portion, said saturated portion having at least some structural rigidity and said unsaturated portion having at least some exposed fibers;
- providing a separator material having a first side and a second side;
- placing said unsaturated portion of said first fabric against said first side of said separator material;
- placing said unsaturated portion of said second fabric against said second side of said separator material;
- adding an electrolyte to said unsaturated portion of said first material;
- adding an electrolyte to said unsaturated portion of said second material;
- and
- sealing said saturated portion of said first fabric to said saturated portion of said second fabric.
