Abstract
An electrode sheet has a first end and a second end opposite each other, and includes a current collector, active materials disposed on a first coated zone and a second coated zone, and a plurality of electrode tabs. The current collector includes a side edge, opposing first and second surfaces. The first surface includes a first coated zone and a first uncoated zone, and the second surface includes a second coated zone. At the first end, the first coated zone and the second coated zone are flush. At the second end, the first coated zone is misaligned with the second coated zone. The sum of the length of the first coated zone and the length of the first uncoated zone is equal to the length of the second coated zone. Each electrode tab is coupled to the current collector and protrudes beyond the side edge.
