This abstract first appeared for US patent application 18286052 titled 'ELECTRODE ASSEMBLY, BATTERY CELL, BATTERY CELL PROCESSING APPARATUS, AND BATTERY PACK AND VEHICLE INCLUDING SAME
Simplified Explanation
The cutting device described in the patent application is designed to cut at least a portion of an uncoated portion of an electrode assembly, which includes a separator, a first electrode sheet, and a second electrode sheet wound in a stack. The device includes a first cutter portion to form first cut lines in the uncoated portion at an axial direction of the electrode assembly while moving in the axial direction, and a second cutter portion to form a second cut line in the uncoated portion at a peripheral direction of the electrode assembly while moving in a radial direction of the electrode assembly. The second cutter portion forms a cut surface portion in the uncoated portion of the electrode assembly by connecting the second cut line to the first cut lines and cutting out a portion of the uncoated portion defined by the first cut lines and the second cut line.
