Soldering 18650 batteries requires careful preparation and technique to ensure secure connections and maintain battery integrity. By using the right tools and following best practices, you can effectively join cells in a battery pack, enhancing performance and reliability in various applications, from DIY projects to electric vehicles. What
The soldering process produces a material-to-material bond between a base material and a metallic filler material (solder). The process is very simple, because only the solder and a soldering iron are needed. Wave soldering is the traditional mounting method for all push-through components on the PCB. The method is described in detail in
Introduction: When it comes to connecting battery cables, choosing the right method is crucial for ensuring a secure and reliable electrical connection. Two popular methods for attaching battery cable lugs are crimping
Even though soldering can create a permanent connection, it can also be reversed using a desoldering tool as described below. Soldering Tools. The good thing about learning how to solder is the fact that you don''t need a lot to get started. Below we''ll outline the basic tools and materials you will need for most of your soldering projects. Soldering Iron. A soldering iron is a
Soldering Iron: The soldering iron heats up and melts solder wire to make connections between wires and battery terminals. A standard soldering iron often operates between 350°F to 400°F (about 175°C to 200°C), which is sufficient for most soldering tasks. According to industry standards, a soldering iron with a fine tip is ideal for precision work.
Compare spot welding and soldering methods for connecting 18650 and 21700 batteries. Learn about the advantages, disadvantages, safety considerations, and best practices for each technique.
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 , .
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.
As defined by the American Welding Society, soldering is done with solders that melt below 450 °C and brazing with solders melting above this temperature . For battery cells the heat input of the connection process has to be relatively low to not damage the battery cell’s internal electrochemical components.
The soldering irons were taken from the battery cells shortly after the solder completely melted. The welding and soldering processes were recorded by the thermographic camera A325sc by the Flir Systems Inc. to track the temperature distribution of the battery cells.
Nevertheless, if a solder with a low liquidus temperature is chosen, this technique is applicable for battery cells, as the results proof. For the investigations on the heat input into battery cells, solders with 90 °C, 124 °C, and 145 °C liquidus temperature were used.
Iron soldering is the most common heating technique used by do-it-yourselfers, researchers, and for prototyping. A soldering iron is pressed onto the solder and thereby transfers heat and melts the solder , . On the one hand, this technique is easy to handle and the equipment is highly available and relatively cheap.
