ABSTRACT:
There is disclosed a long life light weight alkaline storage battery taking the form of a two terminal linear array of cells, the sidewalls, tops and bottom portions of which comprise a pair of molded plastic frames of substantially rectangular section which are joined together in a leak proof manner, with each pair similarly joined to either a similar pair, or to an end frame, while the tube of substantially rectangular sections so formed is compartmented by a series of nickel or nickel plated steel end plates that are entered into the joints between frame pairs during assembly, and that, except in the case of outermost cells, have folded dual porous plate type electrodes, impregnated to be of opposite polarity welded to their opposite sides in such manner that they project perpendicularly from the surface of the end plates to which they are attached and possessing tapered leading edges with the foremost edge unimpregnated to facilitate assembly, there being provision so that, in the assembled battery, within each cell the positive and negative electrodes that are attached to adjacent cell end plates are interleaved, though prevented from contact by separator material, while provision is made so that the outer surfaces of the two outermost cell end plates make electrical connection to battery terminals.
