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.

First claim

The invention claimed is:

1. 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.

2. The method of making electrical cell of claim 1 wherein said step of forming a monolith containing a multiplicity of conductive fibers embedded in a foam comprises forming a monolith containing a multiplicity of conductive fibers embedded in an aerogel.

3. The method of making electrical cell of claim 1 wherein said step of forming a monolith containing a multiplicity of conductive fibers embedded in a foam comprises forming a monolith containing a multiplicity of conductive fibers embedded in an xerogel.

4. The method of making electrical cell of claim 1 wherein said step of forming a monolith containing a multiplicity of conductive fibers embedded in a foam comprises forming a monolith containing a multiplicity of conductive fibers embedded in a carbon nanotube foam.
