What happens if you solder a lithium battery?

The problem with soldering lithium batteries is that the heat from the soldering process damages the cells to some degree. Not only does it damage the cells, but it damages the cells to an inconsistent degree in most cases. This can cause the battery pack to come out of balance later on.

How to solder lithium batteries?

If you are going to solder lithium batteries, apply lots of flux to the cell before touching it with the soldering iron. This will ensure that the cell surface is in the best possible state to be soldered which will require less soldering time for a good connection. In this article, we will discuss how to solder lithium batteries.

How much power do you need to solder a lithium battery?

To solder a lithium battery, you’re going to need at least 100 watts of power at the tip. Having triple-digit watts at your disposal is required to be able to get in there, form an excellent connection, and get you- quick. It may seem counter-intuitive, but the best soldering iron-to-solder lithium-ion batteries is going to be the hottest one.

Can lithium-ion battery cells be soldered with iron soldering?

Of course, due to its massive heat input iron soldering is not the ideal soldering technique for connecting lithium-ion battery cells. Nevertheless, if a solder with a low liquidus temperature is chosen, this technique is applicable for battery cells, as the results proof.

How are batteries soldered?

But also for industrial productions, batteries are soldered as for example the battery modules of the full electric MINI E by the BMW AG . In principal, soldering and brazing are based on a joining process where the joining partners are connected by melting and putting a filler metal, the solder, into the joint , .

Can a soldering iron contact a battery?

Do not allow the soldering iron to make direct contact with the bodies of the batteries. Proceed with the sol-dering quickly within 5 seconds while maintaining the iron tip temperature at about 350°C, and do not allow the temperature of the battery bodies to exceed 85°C. (Heat resistance BR type is 125°C)

Tutorial: Soldering Li-Ion Battery Cells (18650, 18500 21600)

Soldering directly on Li-Ion batteries such as 18650 can be dangerous. I will show you a few tips to do it more safely as overheat can cause fire.

Can you soldier two lithium-ion battery together

Remember which way you connect the batteries makes a difference too. If you connect them in parallel you''ll keep the voltage the same but double the current drive, while connecting them in series doubles the voltage but leaves the current the same. As an example, I''m rebuilding the battery for a vibrating concrete float. It''s rated at 18 volts ...

How to Solder Lithium Ion Batteries and Cells

To be able to solder lithium batteries, you will need an extremely powerful soldering iron of 100 watts or more. A high-wattage soldering iron can solder much faster than a cooler-running one, which results in less heat getting to the cells. Solder the connections to the cells as quickly as you can, so that you spend the least amount of time as ...
