In this work, a two-dimensional, axisymmetric, electrochemical-thermal coupled model is developed for 18,650 lithium–iron–phosphate battery. The battery discharge tests are conducted at different rates and temperatures so as to investigate the effects of ambient temperature and spot-welded nickel strip on battery performance.
Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.

Other joining methods such as micro-tungsten-inert-gas welding (micro-TIG), micro-clinching, soldering, and magnetic-pulse welding exist and have been proposed for battery assembly applications, but they are not well established, and therefore their feasibility is still being evaluated, or they are not widely used in the industry.

A parametric study of the welding of cylindrical Hilumin battery cells to thin sheet connectors was also carried out . The authors investigated the effects of various process parameters such as tip geometry, connector strip material and shape, maximum supply voltage, welding time and force, and the distance between two electrodes.
