1 Scrape the part to be welded clean with a knife or file
2 Because the material of the positive electrode is difficult to tin, it is better to grind a little
3 To prevent the battery from being damaged by high temperature, wrap the battery with a damp cloth
4. Hold the battery with the solder wire with one hand, and solder it with the iron of sufficient temperature with the other hand to tin the positive electrode of the battery
5 The effect of tin cooling 18650 lithium battery how to use electric soldering iron welding method Lithium battery (Li-ion, LithiumIonBattery) : Lithium-ion batteries, with their light weight, large capacity and no memory effect, are widely used as power sources for many digital devices, even though they are relatively expensive. The energy density of lithium ion battery is very high, its capacity is the same weight of nickel metal hydride battery 1.5~2 times, and has a very low self-discharge rate. In addition, lithium-ion batteries have almost no "memory effect" and no toxic substances, which are also important reasons for their widespread use. Also please note that the lithium battery external generally marked with English 4.2 Vlithiumionbattery (lithium battery) or 4.2 Vlithiumsecondarybattery (lithium secondary battery), 4.2 Vlithiumionrechargeablebattery (rechargeable lithium battery), Therefore, when purchasing batteries, users must see the signs on the surface of the battery block to prevent cadmium nickel and nickel-hydrogen batteries from being mistaken for lithium batteries because they do not see the battery type clearly. As we know, the shell of 18650 battery is steel shell, there is no special battery spot welding machine, it is difficult to weld with electric iron. Of course, powerful battery fluxes are now available, and you can easily weld 18650 batteries with them and a regular soldering iron. But this strong flux is corrosive, not only to the battery case and positive electrode corrosion, but also to the soldering iron head. So how do you weld an 18650 battery and battery pack without a battery spot welder? Below, three elder brother with their own practical experience, step by step to teach you how to use the electric iron to weld 18650 battery and assembly into a battery pack. goot is a powerful flux that is believed to have been used by many electric powders to weld batteries. It can also be used to weld stainless steel. The 18650 battery of Yangtze River 2600mah was welded with strong electric flux and soldering iron in order to install a protective plate. The positive electrode of the battery rusted soon after! One of my soldering tips was also corroded. It is said that you need to weld with an all-copper tip to avoid corrosion. 18650 lithium battery assembly method and process The following methods do not use strong flux, only electric iron and solder can be welded 18650 battery. Electric iron with 100W high power, very old wooden handle iron, I believe that some people have not seen this kind of iron. 18650 lithium battery assembly method and process using lead-free low melting point solder, said to contain silver, solder surface is very bright. 18650 Lithium battery assembly Method and process to be welded, one for Sanyo 3350mah, one for Forum trial Wick 2000mah5C discharge version (used to make white mouse). Assembly method and process of 18650 lithium battery negative electrode. Assembly method and process of 18650 lithium battery cathode. Assembly method and process of 18650 lithium battery First scrape or grind the oxide layer on the surface of the two plates of the battery to be welded with a knife. 18650 lithium battery assembly Method and process 18650 lithium battery assembly method and process It is best to use alcohol to clean the battery poles of the ground, and then point a small point of rosin alcohol solution. Fix the battery, use an electric soldering iron to spot the solder on the rosin of the battery, gently grind a few times, and the solder will stick to the battery electrode. Assembly method and process of 18650 lithium battery has been tin positive battery, bright solder joint. 18650 lithium battery assembly method and process 18650 lithium battery assembly method and process 18650 lithium battery assembly method and process The negative electrode of the battery with tin, bright solder joint. 18650 lithium battery assembly method and process 18650 lithium battery assembly method and process In order to test this method can be effective for more 18650 batteries, and take two batteries to test, the following is the power battery of God 2500mah. The assembly method and process of 18650 lithium battery are the same as polishing the place where the battery electrode is to be tinned. 18650 lithium battery assembly method and process 18650 lithium battery assembly method and process This is used in the past flashlight, used to test the release, but no matter the battery discharge voltage is low to 1V, the battery voltage can rise to 3V, several tests are not bad, bull. We're gonna use it for a welding test this time. Assembly method and process of 18650 lithium battery The battery used to have a protective plate, the poles used to have spot welding nickel, this time only in the negative electrode of the nickel plate on the tin. Assembly method and process of 18650 lithium battery Two batteries have been tinned, and the rosin has not been washed off. 18650 lithium battery assembly Method and process 18650 lithium battery assembly Method and process after the rosin is washed with alcohol, the battery electrode is in good tin condition and the solder joint is bright. 18650 Lithium battery Assembly Method and process After the battery is tin, you can begin to assemble the battery pack. Below are five Sanyo 3350mah batteries assembled together. Battery pack assembly also need to use green shell paper to insulate the electrodes, especially the positive electrode should pay more attention to. Auxiliary materials are double-sided tape and CAD drawing of insulation sheet drawings. Battery insulation gaskets are available in TBS and can also be purchased in TBS. There is no ready-made own, a big 1.7mm thick green shell paper only 3 yuan. I could not find the nickel sheet at hand for a while, but I thought there was copper sheet. The copper sheet was 0.3mm thick, which was much better than the nickel sheet of 0.1mm. So I decided to use it.
