UNITED STATES PATENT OFFICE.
ALLAN LEVIN, OF REDIDITGH, ENGLAND, ASSIGNOIt TO SVENSKA ACKUMULATOR AK- IIEIBOLAGET JUNGNER, 01* STOOKHOLM, SWEDEN, A COMPANY OF SzWEDEN.
ELECTRODE I OR ALKALINE ACGUMULATORS.
Application filed February 27, 1326, Serial No. 91,131, and in Great Britain Mareh 2, 1925.
This invention relates to an electrode for an accumulator of the kind comprising a perforated container into which active material is fed.
The object of the invention is to increase the conductivity of such electrodes without appreciably increasing the cost of manufacture or necessitating any substantial. alterations in existing machinery used for their production.
According to the present invention an electrode of the kind described is formed by feeding into a perforated tube or container simultaneously with the active material one or more thin strips, wires or ribbons of metal in such a manner that portions of the strips make contact with the inner walls of the container. The strips may be bent into various shapes such as helices, loops or zigzags and may be so disposed within the container that portions thereof-e. g. the ends of the zig-zag loops make contactwith the inner Walls of the container.
The invention may be carried out in various ways but one construction is illustrated by way of example in the accompanying drawing, in which one form of electrode according to the invention is illustrated in perspective, the various parts being broken away to better illustrate the constructlon thereof. i
In the construction illustrated in the drawing a flat perforated metal container for the active material is formed in the known manner by first producing-as by rolling or stamping-a channelled or trough-like member A, having laterally projecting flanges A A cover plate B, also formed from thin perforated metal, then applied to the trough-like member A, and the edges B of the cover plate are turned over the projecting lateral flanges A- of the trmigh, thereby forming a flattened tubular member having perforated front and rear walls. With the active material is simultaneously fed into the container a metal strip 0 bent into a series of loops or zip;- zags as shown. The plane of the strip C is at right angles to the top and bottom walls of the container and the loops or bonds in the strip are of such dimensions that the outer cnds of alternate loops make contact I with the opposite side walls of the contamer as at C Further, the width of the strip approximately the same as the distance between the front and rear walls of the container so that the edges of the strip make contact with the inner surfaces of these walls, when the container is subsequently compressed.
It will be appreciated that by using electrode plates built up from a number of perforated elements or pockets, each having a metal strip as above described, the conductivity and effective life of the electrode are improved without in any way decreasing the area of the active material exposed to the electrolyte.
VVh-atl claim as my invention and desire to secure by Letters Patent is 1. The method of making an electrode for an accumulator of the type in which a metallic perforated container is provided for the active material which consists in deform ing a metallic strip having a width substantially equal to the depth of the container and adapted to contact with certain of the container walls into a series of loops, each loop having a length substantially equal to the width of the container, and adapted to contact with the other Walls, and feeding the strip and a quantity of active material into the container simultaneously.
2. The method of making an electrode for an accumulator of the type in which a metallic perforated container is provided for the active material which consists in deforming a metallic strip having a width substantially equal to the depth of the container and adapted to contact With certain of the container walls into a series of loops, each loop having a length substantially equal to the width of the container, and adapted to contact with the other walls, feeding the strip and a quantity of active material into the container, and exerting pressure on the walls of the container to cause said walls to con tact simultaneously with the edges of the strip.
In testimony whereof I have signed my name to this specification.
