Abstract:
1. A method for mechanically connecting a plurality of cylindrical battery cells in a battery cell assembly using one or more copper braids and one or more bands, wherein each cylindrical battery cell comprises an elongated body section with a first contact point end that is positively charged and a second contact point end that is negatively charged, the method comprising: arranging the plurality of cylindrical battery cells such that the first contact point ends of the plurality of cylindrical battery cells face a same direction; placing a single first copper braid across the first contact point ends of the plurality of cylindrical battery cells; placing a single second copper braid across the second contact point ends of the plurality of cylindrical battery cells; and wrapping a single band around each of the plurality of cylindrical battery cells securing the first contact point end of each of the plurality of cylindrical battery cells to a portion of the single first copper braid that is in contact with the first contact point end thereby electrically connecting the first contact point ends and securing the second contact point end of each of the plurality of cylindrical battery cells to a portion of the single second copper braid that is in contact with the second contact point end thereby electrically connecting the second contact point ends.
