First claim
Opening claim text (preview).
The invention claimed is: 1 . A method of making electrical cell, comprising the steps of: providing a first current collector having a multiplicity of fibers in a foam; providing a second current collector spaced from said first current collector; and providing a separator disposed between said first current collector and said second current collector. 2 . The method of making electrical cell of claim 1 wherein said step of providing a first current collector having a multiplicity of fibers in a foam comprises providing a first current collector having a multiplicity of fibers in an aerogel foam. 3 . The method of making electrical cell of claim 1 wherein said step of providing a first current collector having a multiplicity of fibers in a foam comprises providing a first current collector having a multiplicity of fibers in an xerogel foam. 4 . The method of making electrical cell of claim 1 wherein said step of providing a first current collector having a multiplicity of fibers in a foam comprises providing a first current collector having a multiplicity of fibers in a carbon nanotube foam. 5 . 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. 6 . The method of making electrical cell of claim 5 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. 7 . The method of making electrical cell of claim 5 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. 8 . The method of making electrical cell of claim 5 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. 9 . 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 and a top; coating said conductive fibers with a dielectric coating to produce coated conductive fibers; forming a potted layer on the bottom of said monolith and on the top of said monolith using a non-electrical conductive material; passivating said conductive fibers on said top of said monolith to provide a non-conducting cover to said conductive fibers; using a plane operation to produce a planed surface on said potted layer on said bottom of said monolith and on the top of said monolith; and applying a conductive coating over said planed surface of said potted layer. 10 . The method of making electrical cell of claim 9 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. 11 . The method of making electrical cell of claim 9 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. 12 . The method of making electrical cell of claim 9 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.
