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 6-10 weight percent polyethylene having a molecular weight of 200,000 to 500,000, 90-94 weight percent of titanium disulfide particulate material and from 0 to 2 weight percent of a plasticizer for the polyethylene; the sheet having a void volume of from 15 to 25 percent.
Claims16
A cathodic electrode suitable for use in a non-aqueous battery system comprising at least one substantially homogeneous, microporous sheet product having a void volume of from 15 to 25 volume percent and having a composition consisting essentially of from about 90-94 weight percent of particulate material consisting essentially of titanium disulfide having an average particle size of less than about 20 microns, from about 6-10 weight percent of high density polyethylene having a weight average molecular weight of from about 200,000 to 500,000 and from 0 to about 2 weight percent of an organic plasticizer for said polyethylene;
- and a current collector composed of a conductive material, said collector being in intimate contact with each of said at least one microporous sheet product.
