Abstract
A battery electrode sheet comprises a conductive substrate and an electrode material coated on at least a portion of the conductive substrate. The coated portion of the conductive substrate comprises a first region, a second region, and a transition region between the first and second regions. The electrode material on the first region has a first thickness; and the electrode material on the second region has a second thickness, which is smaller than the first thickness. The electrode material on the transition region has a thickness that decreases between the first and second regions.
