1. A bus bar, comprising:
a first end including a first material and configured to be coupled to a first terminal of a first battery cell of a battery module;
a first collar disposed on the first end and including the first material, the first collar having a first collar outer circumference and being configured to receive and surround the first terminal;
a second end including a second material and configured to be coupled to a second terminal of a second battery cell of the battery module, the first and second battery cells of the battery module being adjacent to one another;
a second collar disposed on the second end and including the second material, the second collar having a second collar outer circumference and being configured to receive and surround the second terminal; and
a joint electrically and mechanically coupling the first end and the second end, the joint providing a gas tight seal between the first end and the second end; and
a busbar curved portion, the busbar curved portion being concave and comprising a first curved portion and a second curved portion, the first curved portion sloping from the joint toward the first terminal and ending on the first collar outer circumference, the second curved portion sloping from the joint toward the second terminal and ending on the second collar outer circumference.
