Aixcon developed a process to weld copper cell connectors onto battery cells. Using copper as cell connectors increases their electrical conductivity, and thus increases the efficiency of a battery pack compared to commonly used materials (e.g. nickel-plated steel, nickel, etc.). Copper also has superior thermal conductivity, and provides an excellent heat sink for battery cells.
