Title:
STACKED BATTERY, AND METHOD FOR MANUFACTURING STACKED BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/230930
Kind Code:
A1
Abstract:
A stacked battery, provided with a plurality of first electrode plates, a plurality of second electrode plates stacked with the first electrode plates alternately in the stacking direction, a first tab connected to the first electrode plates, and a second tab connected to the second electrode plates. The first electrode plates have a first electrode current collector including a first effective region and a first connection region. The first connection regions are overlapped on the first tab. The first electrode current collector that is set away the farthest from the first tab in the stacking direction is longer than at least one of the other first electrode current collectors. The first electrode plates further have an insulating tape stacked onto the first electrode current collector. The difference in length between the longest first electrode current collector and the shortest first electrode current collector is greater than the sum of the separation spacing, along the stacking direction, between the first effective region of the longest first electrode current collector and the first effective region of the shortest electrode current collector, and the width of the insulating tapes along the direction of arrangement of the first effective regions and the first connection regions.
