Finally, at the optimum parameter combination, the live cell welding was conducted between the Ni tab and both positive and negative terminals of LG HG2 18,650 Li-ion cells, and the joints were relatively strong no intermetallic compounds (IMCs) appeared. Secondly, it was observed that the weld current had the most significant effect on the weld strength followed by weld time. 0.3 mm and 0.4 mm) of Hilumin coupons, representative of negative and positive terminals of 18,650 cylindrical cells. Firstly, the welding pilot runs were conducted between Ni connector and two different thicknesses (i.e. The effect of welding parameters including weld current, weld time, squeeze time, pre-heat current, pre-heat time, dwell time and hold time were investigated to optimize joint strength. This paper is focused on identifying the effect of influencing parameters of the micro-RSW process and developing an optimized joining solution to connect a 0.2-mm-thin nickel tab to 18,650 Li-ion battery cells. The micro-resistance spot welding (micro-RSW) process is one of the commonly used joining techniques for the development of cylindrical cell-based battery packs, especially for low to medium volume applications. In an automotive battery pack, many Li-ion cells are connected to meet the energy and power requirement. Finally, the suistriple welding parameter setting ranges were obtained as a result, which can be applied to create battery packs either from the similar or other different models of 18650 Li-ion cells via series spot welding processes. The electric resistance and mechanical strength of the welded contact were measured. Then, after having the results of studied parameters from both simulations and experiments compared and analyzed, the actual spot welding was conducted between HiluminĀ® connecting strips and both of positive and negative terminals of SAMSUNG INR18650-15L Li-ion battery cells. The trial welding was first performed between two different thicknesses of HiluminĀ® connecting strips themselves. For experiments done in this work, the actual spot welding was conducted using the Miyachi FD120 series spot welding machine. ![]() Simulations were carried out software to observe the deformation, electric current distribution as well as temperature distribution occurred within the models. A sample battery cell was disassembled and measured to create the 3D models. The effects of these parameters were investigated via simulations and experimentations. The welding parameters that were studied in this work include electrode tip geometry, connecting strip material and design, maximum supply voltage, welding time welding force and distance between two electrodes. ![]() Our company takes the revitalization of the national industry as its mission striving to become an internationally renowned brand so that global users can trust 'Made in China'.This work was designed to study the effects of influencing parameters in series/parallel gap spot welding process and determine the optimized parameters setting for spot welding between 18650 Li-ion battery cells and sheet metal connectors.
