Abstract
A battery cell may include a lid, a case, a jellyroll, and a gasket. The lid may include a first pin and a second pin. The case may form a chamber when sealed with the lid. The jellyroll may include a negative electrode having a negative electrode tab and a positive electrode having a positive electrode tab. The jellyroll may be disposed inside the chamber. The negative electrode tab may couple with the first pin to form a negative terminal of the battery cell and the positive electrode tab may couple with the second pin to form a positive terminal of the battery cell. The gasket may partially encase each of the negative electrode tab and the positive electrode tab to prevent a contact between the negative electrode tab, the positive electrode tab, and/or the case of the battery cell.
