Fabrication Methods For Low Impedance Lithium Polymer Electrodes
US Patent:
5698147, Dec 16, 1997
Filed:
May 24, 1996
Appl. No.:
8/653170
Inventors:
Terry Song-Hsing Chern - Midlothian VA Kenneth Orville MacFadden - Highland MD Steven Lloyd Johnson - Arbutus MD
Assignee:
W. R. Grace & Co.-Conn. - New York NY
International Classification:
C04B 3500
US Classification:
264104
Abstract:
A process for fabricating an electrolyte-electrode composite suitable for high energy alkali metal battery that includes mixing composite electrode materials with excess liquid, such as ethylene carbonate or propylene carbonate, to produce an initial formulation, and forming a shaped electrode therefrom. The excess liquid is then removed from the electrode to compact the electrode composite which can be further compacted by compression. The resulting electrode exhibits at least a 75% lower resistance.

International Classification:
H01M 462, H01M 1040
US Classification:
429194
Abstract:
A polymer bonded sheet product suitable for use as a cathodic electrode in a non-aqueous battery system wherein the cathodic electrode is a microporous sheet composed of from 2-30 weight percent polyethylene, 70-98 weight percent of electrically conductive and electrochemically active particulate material and from 0 to 5 weight percent of a plasticizer for the polyethylene.
