Welding techniques for battery cells and resulting electrical contact resistance ~ The compared techniques are resistance spot welding laser beam welding and ultrasonic welding. The weld nugget size is usually defined by the electrode tip contact. Contact resistance is an important factor in the first few milliseconds of a weldCombined with bulk resistance the contact resistance value of the workpieces electrodes and their interfaces both cause and affect the amount of heat generated. The current and the heat generation are localized by the form of the electrodes.
In resistance welding contact resistance is a function of the extent to which two surfaces come in contact. Finally the suistriple welding parameter setting ranges were obtained as. Electrical joints with a low contact resistance and a high mechanical strength can be achieved. The weld quality of the joint is an important factor in determining the performance and safety of the battery.
Round cell is done with Telsonic Ultrasonics using the longitudinal or alternatively the torsional welding. Spot welding is a resistance welding process for joining metal sheets by directly applying opposing forces with electrodes with pointed tips. As different welding position sequences for three. Resistance spot ultrasonic or laser beam welding are mostly used for connecting battery cells in the production of large battery assemblies.
This technique works because the heat generated in the work piece is distributed based on where the electrical resistance is. A higher electrode force will reduce contact resistance which in turn will reduce heat at the contact points electrode-to-part and part-to-part interfaces. The joining techniques with application for battery tab interconnects are ultrasonic metal welding resistance spot welding and pulsed TIG spot welding. Cell casing and terminal dimensions may constrain possible contact geometries.
The performance was evaluated in terms of numerous factors such as production cost degree of automation and weld quality. In the penultimate section of this work soldering is compared to welding techniques and press contacts in terms of electrical connection resistances and ultimate tensile force. Owing to the sur-. The resistance spot ultrasonic laser welding micro friction stir blind riveting FSBR micro friction stir forming FSF and micro friction stir welding FSW are the common joining techniques.
To weld different positions it results in structural deformation of the positive battery terminal which directly affects the contact pressure. Although soldering techniques have some significant advantages welding techniques such as spot and laser welding are mostly used within the industrial production of batteries. 1b surfaces irregularities are schematically shown in a magnified portion of the contact interface. In order to highlight the importance of contact resistance we consider two electrically conductive bod-ies which are in contact under an applied force F see Fig.
In common battery assemblies the joint between the battery cell and the current collector cell connector is realized by different welding techniques like spot laser beam or ultrasonic welding. Laser welding with high power fiber laser systems can produce complete battery modules that reach the capacities and cell voltages eg 400 V or 800 V required for electrical vehicles 3. Lap shear and T-peel tests are performed to evaluate the joint strength. For example pouch cells provide detached tabs whereas cells.
An alternative joint for connecting battery cells is a clamped electrical contact. Each of these welding techniques has its own characteristics depending on the material properties and contact geometry. Resistance spot ultrasonic or laser beam welding are mostly used for connecting battery cells in the production of large battery assemblies. Welding techniques for welding batteries.
The contact between the tab and the inner cell casing must be mechanically strong and have low electrical contact resistance. In the cell assembly the bonding of the conductor foils anode - copper and cathode - aluminium with the cell conductors pouch cell or with the contact terminals eg. Resistance spot welding RSW works on the principle of electrical resistance at the mating surfaces when high current passes through them creating localised heating and fusion of materials under pressure. The results presented in this paper show that laser beam welding with continuous wave radiation is a suitable joining process for the electrical connection of 26650 battery cells while avoiding a critical temperature change within the cells.
