What to pay attention to when soldering lithium batteries to terminals and circuits

Do not let the tip of the soldering iron touch the surface of the battery. The tip of the soldering iron will become very hot. In order to solder properly, you have to heat your soldering iron to 350°C. However, the surface of most lithium batteries can only withstand high temperatures as high as 125°C. This is why you have to be very careful and beware of touching the tip of the soldering iron to the surface of the battery. Whenever soldering, place a solder bead on the top of the soldering iron, and only let the solder bead contact the battery. Next, while the tip of the soldering iron is in direct contact with the surface of the battery, disperse the solder beads. All of this should be completed within 5 seconds. If it is too long, the surface of the battery will become too hot, which can cause damage. Do not use reflow soldering for most lithium batteries. Reflow soldering is a quick and effective way to connect surface mount components to the circuit board, but it should not be used when soldering lithium batteries. The heat generated in this process is indeed too much for lithium batteries. When exposed to such a large amount of heat, most lithium batteries start to leak electrolyte, or in the worst case, will explode. Lithium is a temperature sensitive material. It does not need too much heat to melt into the battery isolation layer and cause a short circuit, so please always be careful. Straight welding of lithium batteries is not only dangerous, but also harmful to the environment. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
