Abstract
An electrode includes a current collector comprising a grid, said grid comprising a plurality of planar, parallel rows disposed between interleaved rows having raised and lowered segments, and a tab portion extending from a side of the current collector. Raised and lowered segments are disposed horizontally relative to the tab portion, thereby providing substantially uninterrupted conductive ribbons extending from the bottom of the current collector to the tab portion.
