Abstract
A battery pack including a supporting structure, a battery cell housed within the supporting structure, a sleeve partially surrounding the battery cell, a bus bar, and a wire. The sleeve extends over a portion of a first end of the battery cell and has a laser-cut cutaway portion exposing a laser-cleaned first bonding area of the first end of the battery cell. The laser-cleaned first bonding area is positioned adjacent to an outer perimeter of the first end of the battery cell. The bus bar has a laser-cleaned second bonding area. The wire is bonded to the first and second laser-cleaned bonding areas to electrically connect the battery cell to the bus bar.
