Abstract
Abstract A battery is disclosed in which each cell electrode structure comprises an assembly of a single first electrode of one polarity separated by a separator from a single second electrode of the other polarity, the assembly being arranged to provide an array of multiple layers of electrode of alternating polarity, an integral portion of the first electrode extending out to one side of the cell and integral portion of the second electrode extending out to the other side of the cell, one integral portion being connected to or integral with an electrode support structure in the adjacent cell, or a battery terminal, on its side of the cell, and the other integral portion being connected to or integral with an electrode support structure in the other adjacent cell on its side of the cell.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
167 words
A multi-cell lead acid electric storage battery in which each cell electrode structure comprises an assembly of a single first electrode incorporating a lead support of one polarity separated by a separator from a single second electrode incorporating a lead support of the other polarity an integral portion of said first electrode support extending out to one side of its cell and an integral portion of said second electrode support extending out to the other side of its cell, said first integral portion being connected to or integral with an electrode support structure in the adjacent cell, or a battery terminal, on its side of each cell, and the other integral portion being connected to an integral with an electrode support structure in the adjacent cell on its side of each cell, said integral portions extending substantially the full width or substantially the full height of the side of each cell, the cells being arranged to provide an array of multiple layers of electrodes of alternating polarity.
Claim 2
Dependent Claim
167 words
A multi-cell lead acid electric storage battery in which each cell electrode structure comprises an assembly of a single first electrode incorporating a lead support of one polarity separated by a separator from a single second electrode incorporating a lead support of the other polarity an integral portion of said first electrode support extending out to one side of its cell and an integral portion of said second electrode support extending out to the other side of its cell, said first integral portion being connected to or integral with an electrode support structure in the adjacent cell, or a battery terminal, on its side of each cell, and the other integral portion being connected to an integral with an electrode support structure in the adjacent cell on its side of each cell, said integral portions extending substantially the full width or substantially the full height of the side of each cell, the cells being arranged to provide an array of multiple layers of electrodes of alternating polarity.
Claim 3
Dependent Claim

Claim 7
Dependent Claim
55 words
A battery as claimed in claim 1 in which the conductivity of the integral portion of the conductive support structure is enhanced by casting additional metal onto it or by attaching a metal fillet to it or by forming it with a greater cross sectional area of metal than the remainder of the conductive support.
Claim 8
Dependent Claim
42 words
