Abstract:
1. An apparatus comprising: a first cell element having a first flat surface and a second flat surface, and the first cell element having a uniform height between the first flat surface and the second flat surface; a second cell element, the second cell element to be stacked on a first portion of the first flat surface of the first cell element, the first cell element and the second cell element to form a non-uniform battery cell having a first battery cell height and a second battery cell height, the second battery cell height being at a first area in which the second cell element is stacked on a first portion of the first cell element and the first battery cell height at a second area corresponding to a second portion of the first cell element, and the second battery cell height is greater than the first battery cell height; a first bus bar to electrically couple to a first end of the first cell element and to electrically couple to a first end of the second cell element, the first bus bar having a first bus bar height corresponding to the first battery cell height and a second bus bar height corresponding to the second battery cell height, the second bus bar height being greater than the first bus bar height; and a second bus bar to electrically couple to a second end of the first cell element and to electrically couple to a second end of the second cell element, the second bus bar having a third bus bar height corresponding to the first battery cell height and a fourth bus bar height corresponding to the second battery cell height, the fourth bus bar height being greater than the third bus bar height.
