Can solder be used to connect the positive and negative electrodes of ternary lithium batteries?

The positive and negative electrodes of the Pacific Automotive Network ternary lithium battery can be connected by welding. The 18650 lithium battery can be welded with WEWELDING M51 tin alloy welding wire suitable for different welding of copper and aluminum. M51-F flux is required for welding. Polish it in advance, then use a soldering iron to preheat the auxiliary aluminum sheet in advance, then use a welding wire dipped in the flux to lower the welding wire to the solder joint, and in same time. use the preheat soldering iron to help the solder wire dipped in the flux melt and form.

The metal casing of lithium batteries is usually nickel-plated. It is not easy to directly solder solder on this nickel-plated case. If the amount of solder is not large, just a few solder joints, you can use a file to process firstthe parts of the lithium battery that need to be soldered to make the surface rougher, then apply a little rosin water and use a stronger product. electric soldering iron to melt the solder wire, plated on the surface of the battery, so that it is easy to solder with solder wire. The disadvantage of using the above soldering method is that the solder joints are not very firmly attached and may unsolder after being subjected to stress. In addition, long welding time is not good for lithium batteries. If you want to solder lithium batteries, the easiest way is to use multifunctional metal flux to solder. Multifunctional metal flow. The multifunctional metal flux shown in the picture above can easily weld the pole pieces of stainless steel and battery. When using, first clean the area where the battery in thelithium needs to be soldered, then apply multifunctional flux to the area where the lithium battery needs to be soldered, so that the solder can be soldered to the lithium battery.

After using the flux, solder was soldered on the positive and negative electrodes of the lithium battery.

The wires are soldered to the 18650 lithium battery. The cathode of the lithium battery tab is copper foil and can be soldered directly. The whole machine is generally aluminum foil and cannot be soldered with an ordinary soldering iron. Generally, it needs to be converted into nickel sheet (spot welding with a spot welding machine) before it can be welded with ordinary solder.

How about the power bank for post welding?< /h3>

The battery cannot be exposed to dHigh temperatures Generally, manufacturers use laser welding to solder lithium batteries, and the tabs can be soldered with an electric soldering iron. If it is aluminum tabs, you can use WELDING at low temperature of 179 degrees

M51 welding wire combined with M51-F When used with flux, the success rate is very high.

The power bank made with this kind of craftsmanship is good.

According to information from Daoke Baba, tab soldering technology is a new way of connecting electronic components. It uses pressure heating to solder two metal terminals to make the circuit board stronger. and more reliable. The power bank uses lug welding technology, which can effectively solve the problem of easy falling off of solder joints of ordinary power bankses and improve the security and stability of the power bank.

The main features of tab welding technology are simple operation, fast welding speed, high quality solder joints and little damage to welding materials, ensuring the reliable quality of the power bank. In addition, lug welding technology can make the circuit board and lithium battery inside the power bank more closely integrated, greatly reducing the space occupied by the components, making the whole The power bank is small and portable.
