The aim of this study was to characterize selected properties of joints made by single-sided serial resistance spot welding of 0.15 mm thickness Hilumin connectors to the negative terminal of LGDBHG21865 lithium-ion cylindrical battery cell. Welding process was performed using production parameters to properly represent actual manufacturing conditions. Mechanical properties of the joints were examined by means of tensile stress test and microhardness measurements while additional studies include metallographic analysis of the joint cross sections by means of optical and scanning microscopy. Energy dispersive spectroscopy was performed in order to determine surface distribution of elements within the weld nugget. Studies confirmed suitable microstructure of welded joints, repeatability of the welding process and proper selection of the welding parameters.
