ABSTRACT:
The present invention relates to a current collector for an electrochemical cell. The current collector is a substrate having a grid pattern comprising open areas converging at an imaginary focal point on a connector tab of the substrate. The openings are grouped into distinct regions with the larger openings immediately adjacent to the connector tab and the smaller openings distant there from. This provides more conductive pathways at greater distances from the tab.
