Abstract:
A method of constructing multicell batteries utilizes a continuous web comprising a plurality of structurally connected continuous Zones at least one of which comprises a continuous strip of metal. Deposits of electrodes are placed along the Zones of the continuous web after which the web is cut to structurally disconnect the continuous Zones from each other. Pockets are then indented in a Zone comprising a continuous strip of metal, the indenting being done in a manner which results in the pocketed Zone having the same relative longitudinal length after the indenting as it had before the indenting. Finally, the pocketed Zone is collated into an assembly of battery components which includes at least one other continuous Zone from the web. The indenting may be preceded by the cutting of a slit partially across the Zone to be pocketed, in which case the width of the slits is increased but the center lines of the slits remain in fixed relative longitudinal position by the indenting action. The method is applicable both to webs having metal and plastic laminations and to all metal webs.
Abstract:
A HOLE IN THE TOP OF A BATTERY IS COVERED BY A GAS PERVIOUS, LIQUID IMPERVIOUS MEMBER SECURED TO THE INTERIOR SURFACE OF THE TOP IN A MANNER WHICH PROVIDES A LIQUID-TIGHT CLOSURE AROUND THE HOLE. THE GAS PERVIOUS LIQUID IMPERVIOUS MEMBER MAY BE EXTENDED TO AND AROUND THE EDGE OF THE TOP WHERE IN IS CRIMPED BY THE CONTAINER AND WHERE IT FUNCTIONS AS A GROMMET TO PROVIDE A LIQUIDTIGHT CLOSURE AROUND THE PERIMETER OF THE TOP. THE GAS PERVIOUS, LIQUID IMPERVIOUS MEMBER MAY BE CRIMPED BETWEEN THE TOP AND AN ELECTRICALLY CONDUCTIVE CURRENT COLLECTOR WHICH IS SECURED TO THE TOP. CONSTRUCTIVE ARE ILLUSTRATED IN WHICH THE GAS PERVIOUS, LIQUID IMPERIOUS MEMBER IS ELECTRICALLY NONCONDUCTIVE, WHILE OTHER CONSTRUCTIONS ARE SHOWN IN WHICH THE MEMBER IS CONDUCTIVE.
