Claims10
A battery comprising:
- a battery cell;
- a first tab extending from inside the battery cell to outside the battery cell and including a first reaction region and a first welding region,
- a second tab extending from inside the battery cell to outside the battery cell and including a second reaction region and a second welding region;
- wherein the first reaction region extends from the battery cell in a first direction,
- wherein the first welding region extends from the first reacting region to outside the battery cell in the first direction,
- wherein the first reaction region and the first welding region are arranged side by side in the first direction and do not overlap each other,
- wherein the second reaction region extends from the battery cell in a second direction,
- wherein the second welding region extends from the second reacting region to outside the battery cell in the second direction,
- wherein the second reaction region and the second welding region are arranged side by side in the second direction and do not overlap each other,
- wherein the first welding region is formed of the same material as the second welding region, and
- wherein first reaction region is formed of different material from the second reaction region.
