Can You solder a lithium battery pack?
If, however, you are either very determined or have no other option when building a lithium battery pack soldering is certainly possible. To solder lithium batteries properly, you need a very high-power soldering iron.
Do you need a soldering iron to solder lithium batteries?
To solder lithium batteries properly, you need a very high-power soldering iron. This may seem paradoxical at first, but a high-powered soldering iron is able to perform soldering operations much quicker, resulting in less overall heat being imparted into the cells from the hot solder.
How do you solder a Li-Ion battery cell?
Before soldering, use sandpaper to scratch the top and bottom sides of the cell, removing the oxide layer. This will help the solder adhere better. ‘Tin’ both sides of the batteries with a small amount of solder, allowing it to cool down before soldering the wires. Keep the time your soldering iron touches the battery terminals to a minimum.
How can you minimize heat buildup when soldering a battery?
To accomplish this, use a powerful, temperature-controlled soldering iron. Keep the time your soldering iron touches the battery terminals to a minimum. The longer the iron is in contact with the battery, the more heat will build up.
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)
Do lithium cells need advanced soldering?
With soldering lithium cells, it’s a different story. Because of the fact that advanced soldering is required to solder lithium cells, it cannot easily be learned on the spot simply so that another task (building a battery) can be completed.
