Abstract

Abstract Electrodes utilized in various types of batteries are interconnected by means of a pair of conductive bands insulated from each other and bent into a zig-zag formation. Each conductive band overlays an electrode of one polarity, thus performing the function of separator as well as terminal conductor. Upon compression of the stacked electrodes into a housing, a compact battery is produced.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 87 words
The method of assembling and interconnecting a plurality of electrodes to form a battery which comprises placing a band consisting of a pair of electrolyte permeable conducting strips separated by a permeable insulating strip in zig-zag formation around a plurality of electrodes in such manner that each electrode of one polarity is enveloped by one conductive strip of said band and each electrode of the opposite polarity is enveloped by the other conductive strip of said band and pressing said electrodes together to form a stacked assembly.
Claim 2
Independent Claim 87 words
The method of assembling and interconnecting a plurality of electrodes to form a battery which comprises placing a band consisting of a pair of electrolyte permeable conducting strips separated by a permeable insulating strip in zig-zag formation around a plurality of electrodes in such manner that each electrode of one polarity is enveloped by one conductive strip of said band and each electrode of the opposite polarity is enveloped by the other conductive strip of said band and pressing said electrodes together to form a stacked assembly.
Claim 3
Dependent Claim 46 words
The method in accordance with claim 1 wherein said electrodes are placed in a tubular structure having a piston, said structure being placed over an insulating housing accommodating said electrodes, stacking of said electrodes into said housing being effected by exerting compressive force on said piston.
Claim 4
Dependent Claim 65 words
The method in accordance with claim 2 wherein, upon compression of said piston, said housing is removed for placement in a metallic shell, one of said conductive strips, emerging at one end, engaging said shell and causing the latter to become one polarity of a battery, and the other of said conductive strips emerging at the other end, representing the other polarity of said battery.
Claim 5
Dependent Claim 90 words
Interconnecting and insulating means for electrodes of diverse polarity place one above the other, comprising a band consisting of a length of a conductive strip, a length of an insulating strip, and another length of a conductive strip, said insulating strip being firmly secured between said conductive strips, permitting deformation of said band without disturbing the relative position between said conductive strips and said insulating strip, said band being flexible for placement in zig-zag formation over said electrodes and permeable to the electrolyte by virtue of perforations throughout its length.
Claim 6
Dependent Claim 90 words
Interconnecting and insulating means for electrodes of diverse polarity place one above the other, comprising a band consisting of a length of a conductive strip, a length of an insulating strip, and another length of a conductive strip, said insulating strip being firmly secured between said conductive strips, permitting deformation of said band without disturbing the relative position between said conductive strips and said insulating strip, said band being flexible for placement in zig-zag formation over said electrodes and permeable to the electrolyte by virtue of perforations throughout its length.
Claim 7
Dependent Claim 39 words
Interconnecting the insulating means in accordance with claim 4 wherein one of said conducting strips extends beyond said insulating strip at one end and the other of said conducting strips extends beyond said insulating strip at the other end.
