Customer Servicebattery cells must be assembled and connected in serial/parallel for battery packs. Consequently, many electrical connectors are required as electrical bridges between battery cells. For most 18650 Li-ion battery cells, either spot or laser welding technique can be used to weld a sheet metal connector with a battery cell.
Customer ServiceActually an important part of nickel strip is that it''s not very conductive which leads to it heating up and fusing when it is spot welded. Copper and aluminum are difficult to impossible to spot weld. You need ultrasonic welding to do it well. My friend experimented with a TIG welder with a custom electrode and ground jig and he had

This welding process is used primarily for welding two or more metal sheets, in case of battery it is generally a nickel strip and positive terminal/negative terminal of the battery together by applying pressure and heat from an electric current to the weld area. Advantages: Low initial costs.
Can be used to weld critical parts like battery tabs and foils. Challenges faced by using laser welding: Wire bonding is well matured technology which was invented for the semiconductor industry and standard technology for semiconductor chips since 1970s, and also Tesla and ola electric batteries are wire bonded.
Cannot be used for complex battery design or shape. Ultrasonic welding is a solid-state welding technique. In this type of welding workpieces are not melted but pressed and scrubbed together with high frequency vibrations hence no need of electrode, filler material.
