AI Customer ServiceThe three most common metal-to-metal joints in a lithium-ion battery pack are foil-to-tab, tab-to-tab, and tab-to-bus. All three joints pose joining challenges, but of the three, welding multiple layers of foil to a tab is the most challenging. The joint is often made up of dissimilar metals, and the metal thicknesses are mismatched.
Both spot welding and soldering lithium cells suffer in regard to repairability. This is because both the spot welding and soldering processes are inherently permanent and offer no built-in way of being reversed. Spot welding cells has the advantage that in order to remove a welded connection, your only option is to tear it off.
It takes a high degree of skill to solder lithium cells. It’s not something that can easily be learned on the spot so that you can build a battery pack with 18650 cells. Soldering lithium cells requires a type of soldering that takes great skill to master. Spot welding, on the other hand, can be learned relatively quickly.
Soldering can be used for joining pouch cell tabs. It is especially desirable for joining dissimilar materials, but the use of flux can increase the chance of corrosion which can directly affect the strength of the joint.
A spot welded battery will be at least an order of magnitude easier to build than a soldered lithium battery, and both are equally as difficult to repair due to the permanent nature of the two connections. In this article, we will discuss soldering vs spot welding lithium cells.
A solder joint, on the other hand, is a large structure that extends off the surface of the plane it is being soldered to. This makes a soldered connection physically stronger, but again, this extra strength is not needed and comes at the cost of several other key performance metrics.
