Abstract
An electrical cell apparatus includes a first current collector made of a multiplicity of fibers, a second current collector spaced from the first current collector; and a separator disposed between the first current collector and the second current collector. The fibers are contained in a foam.
Claims4
A method of making electrical cell, comprising the steps of:
- forming a monolith containing a multiplicity of conductive fibers embedded in a foam, said multiplicity of conductive fibers extending throughout said foam and said monolith having a bottom;
- coating said conductive fibers with a dielectric coating to produce coated conductive fibers;
- forming a potted layer on the bottom of said monolith using a non-electrical conductive material;
- using a plane operation to produce a planed surface on said potted layer on the bottom of the monolith;
- applying a conductive coating over said planed surface of said potted layer;
- and
- infusing a conductive material into said monolith.
