Lithium-ion Battery Soldering Tricks

[Faeris]

Идея отличная (чот я сам не додумался) только одно НО! - флюс смывать надо! Иначе разъест металл и проводника и батареи!
Сам об это обжигался в начале.
Смывать с аккумов надо спиртом и ещё "капать" на "плюс" надо буквально смочив зубочистку. Что бы он не затёк куда не надо.

I see several comments that mention scuffing or sanding the surface first. I do believe this would create a better bonding surface as well. I don't own a spot welder yet, until I do I am glad I saw this tip because I have had times where I have to solder new tabs to a battery and don't get good results, I do believe this method of drilling the hole will allow a better hold on the strip/tab. Thanks for showing this, I think its a great alternative idea to spot welding.

Nickel tape is only necessary if you want to weld. If you solder, you can user copper wire which has lower resistance.

[Jolteon]

Spotwelding. Safer and faster. But this idea is still clever if your only option is soldering.

[darksoul]

I just scratched the top of the battery and then solder sticks easily

[badeadrian]

I used to do solder on lithium cells... luckily i have bought a spot welder... faster and more safe... really good trick if you don't have a spot welder 👍

Надеюсь это не кислота! Лучше использовать специальный безотмывочный флюс, пользуюсь NC-559-ASM, прекрасно паяет никелированную ленту. А при пайке кислотой потом может буть много проблем в связи с окислением металла. А вот идея с отверстием хорошая, я просто наношу припой с двух сторон ленты и это позволяет быстро распределить тепло и припаять её.

[rumataistorski]

Если паять, то использовать логичнее, медную фольгу. А флюс наносить, ушным тампоном, смоченным флюсом.

Повезло, что лента не проплавила изоляцию до минуса. Для этого есть картонные колечки, что бы обезопасить этот участок.

You can solder cells without damaging them, you use a hot soldering iron and don't let it sit in one spot for very long, I have soldered cells that have got warmer in use than what they do with soldering them. I do have a spot welder, but there are times when you need to solder.
I like this guy's trick but I also lightly sand the area where the solder will be on the strip and cells, it might not be needed but it can't hurt and I am never against overkill if it produces better results.

I did that too. I had to solder two NiMh batteries together and I don't have a spot welder.
I roughened the surface with sand paper.
Then add flux and set the soldering iron to 400°C.
This allows the tin to be heated quickly and the soldering iron to be removed quickly.
Always let it cool down.
Then solder the tinned cable, quickly and hot. Do not solder cold and for a long time.
Always quickly and then cool down

I don't have a spot welding tool. I clean both sides and either sand paper to scratch surface or use a sharp blade to score/scratch lines onto terminals test the soldering guns temp if solder melts it's at max temp. Drill holes into the metal tabs add some solder to all surfaces. Then solder tabs to the terminals. The pre solder will flow immediately. Use a high speed fan until surfaces are cool to touch.

Bueno días colega excelente trabajo saludos desde Argentina

TQ. Great idea. No, the heat won't damage the battery due to the short durations required to solder (pre-tin). More ic's components gets destroyed from soldering heat. No, the soldering solution is not corrosive vs standard soldering paste because it is a new type of wet solution base that evaporates with no corrosive residue (like alcohol eveporation with no residue left-over). Available from Amazon, Lazada, any online shopping... search soldering paste.

[RaymondCHowes]

Really like this idea. What is the fluid used?

[saravananar]

❤for your kind attention,

He is soldering the positive part with the postitive part leaving this might be dangerous when we connect the other two terminals as it will catch fire or release smoke causing damage to the battery as well as your circuit.

BE CAUTIOUS!❤

[christopherleubner]

Lightly sand the terminals of the batteries with a dremel tool. Next apply a sparing amount of tinning flux.Then tin both ends. Solder with good quality solder. Prep the strips or wire with solder. Then solder fast using a hot iron. Soldered joints can carry a lot more current than thin tab material.

Капитан очевидность )))!
А насчёт смывки флюса или его минимального количества в комментариях ниже полностью согласен )!

[carlosclaptrix]

Nice video.
What I don't like:
Giving a heart instead of an answer to a question. Silly.

[AKEUC-wl]

That's actually an excellent idea
