CAT-HOD E-PLATE FOR BATTERI ES.

To all whom it may concern/.-

Beit known that I, HARRY O. HUBBELL, a citizen of the Uni ted States, residing at Jersey City, in the county of Hudson and Stateof New Jersey, have in vented new and useful Improvements in Cathode-Plates for Batteries,

01 which the following is a specification.

This invention relates to cathode-plates for zinc being deposited upon the plate or holder when the battery is under charge.

I It is one of the principal objects of'my present invention to provide a battery-plate of low resistance and high conductivity which will be stable and permanent and which will oxidize freely and reduce readily. These and other objects are attained by means of the batteryplate illustrated in the accompanying drawings, in which Figure l is a perspective view of a cathodeplate made in accordance with my invention. Fig. 2 is a sectional View or" a cathode-plate contained Within a wire-cloth pocket or sack.

In making up my catliode plate I use fine hair-like fibers or filaments of nickel, which may be produced in various ways, but which I preferably produce by means of electrolysis at a liigh voltage or amperage. These hair like nickel fibers are mixed and intermingled with an oxid of nickel, which is moistened and formed into a dough-like or pasty plastic mass. The hair-like fibers are thoroughly incorporated with the oxid mass, the quantity of fibers preferably being greater both in weight and bulk than the oxid. mass, the said fibers or filaments serving to gather and hold or bind the oxid mass into a mat-like or matted mass,

cake, or brick, which may be formed or molded.

by kneading into any required shape. To give greater stability and peri'nanency to the elefnent, I prefer to place the matted material into pockets or bags made of iron or nickelplated-iron wire-cloth or gauze of fine mesh.

,In this manner a comparatively large quan-v tity of material may be made to occupy but a. small space, and thus affords a compact and stable battery-plate of great'permanency and efficiency at a slight cost.

The hereinbefore-described fibrous structure which'serves to hold the oxid mass to' It has been proposed to'use sticks, flakes, Y

or particles of graphite or'other finely-divided carbon or comminuted particles of lead and certain other minerals with oxid of nickel; but owing to the difierent specific gravitics of :the two materials in this form separation and disintegration of the structure are liable to be soon accomplished. To overcome this defect in this character of battervplates, I have provided the foregoing construction.

.Referring to the drawings, the numeral 1 det' nates the intertwined hair-like nickel.

fibers, and 2 denotes the oxid-of-nickel mass. shown, the filaments of nickel extend in all directions and interlock one strand with another and are held in a firm cake, mat, or brick like form with the plastic oxid.

In Fig. 2 I have shown a quantity of the cake or mat inserted in a wire-gauze pocket 3, said pocket being made of iron or nickelplated-iron gauze or wire-cloth of fine mesh.

From the foregoing it will be obvious that my invention provides a permanentand durable battery cathode-plate which may be produced at comparatively slight cost and which has many advantages in use over the structures and materials commonly utilized for this purpose.

Having thus fully described my invention, what idesire to secure by Letters Patent and claim is 1. A storage-battery cathode composed of hair-like fibers of nickel intertwined and embedded in a mass of nickel oxid, forming a plastic mat or cake.

A cathode comprising hair-like fibers of ickel and a mass of plastic nickel oxirl fanned U150 a. mat-like body.

3. A batterymlate composed of nickel filaments interlocked in a mass of nickel oxid in nasty 0r dough-like condition and forming mat or cake.

i. A cathode consisting of hair-like nickel fibers mixed and intertwined with a mass of nickel one] and inserted ina wire-gauze pocket I or sack.
