Most lead-acid batteries are welded through the partition (TTP). Getting inter-cell welding right is the key to healthy batteries and low rejection rates. With more than three decades of experience and dozens of registered patents, Battery Technology Source is universally recognized as the leading inter-cell welding expert.
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
Inter-cell welding (ICW) is the process of fusing the lead straps to connect the batteries’ cells. Most lead-acid batteries are welded through the partition (TTP). Getting inter-cell welding right is the key to healthy batteries and low rejection rates.
With more than three decades of experience and dozens of registered patents, Battery Technology Source is universally recognized as the leading inter-cell welding expert. Our welding machines smartly adapt to the condition of the straps after the COS, providing excellent results regardless of their temperature and hardness.
As external conductor a CuZn37 sheet of 0.2 mm thickness was welded at the negative pole of the cell. The negative tab of the battery cells is made of nickel-plated steel. Welding results for the 26650 lithium-ion cells and the chosen geometries of the weld areas are shown in Fig. 16.
