Patent ID: 8276695

Claim:
A battery electrode sheet comprising: a rectangular conductive substrate comprising a first side, a second side, a third side, and a fourth side; wherein the first side is opposite to the third side and the second side is opposite to the fourth side; and an electrode material coated on at least a portion of the conductive substrate to form a coated portion; wherein the coated portion of the conductive substrate comprises a first region defined by the first side and a portion of the second side and a portion of the fourth side, a second region defined by the third side and a portion of the second side and a portion of the fourth side, and a transition region located between the first region and the second region; wherein the electrode material on the first region has a first thickness; the electrode material on the second region has a second thickness, smaller than the first thickness; and the electrode material on the transition region has a thickness that decreases from the first region to the second region.
