Patent ID: 8088516

Claim:
A battery cell comprising: first electrodes of one polarity; second electrodes of opposite polarity interleaved with the first electrodes; wherein each of the first and second electrodes comprises a sheet of a non-woven fabric having a first edge from which a portion of the non-woven fabric projects forming a tab, and a second edge transverse to the first edge, the non-woven fabric is plated with the metal, wherein a greater density of the metal is deposited along the second edge so as to form a strip along the second edge which has a greater electrical conductivity and a greater weight per unit of surface area than metal coated areas of the sheet more remote from the second edge, the strip extending along the tab; a first terminal attached to each tab of the first electrodes and electrically connected to the strip along that tab; and a second terminal attached to each tab of the second electrodes and electrically connected to the strip along the tab of the second electrodes.
