BATTERY ELECTRODE WITH NON-UNIFORM TAB

An electrode includes a body and a tab extending from the body. The tab includes a first cross-sectional area at a first location along a length of the tab, a second cross-sectional area at a second location along the length of the tab, and a third cross-sectional area at a third location along the length of the tab, where the second location is between the first location and the third location. The second cross-sectional area is less than at least one of the first cross-sectional area or the third cross-sectional area.
