The ''green blue sludge'' here is the result of electrochemistry in action. Adding the salt provides Chlorine Cl- and Na+ ions to the water to carry the charge which increases the reaction rate by allowing a current to flow from the battery. It is ionic and elemental copper Cu2+ and Cu being formed due to the flow of electrons through the conductive salt solution (essentially shorting the battery and corroding the anode terminal). Basically electrolysis is occurring at the copper battery terminals + - where positive (anode) Cu wire oxidizes giving up 2 electrons 2e- to from Cu2+ . Another reaction taking place on anode is two Cl- ions oxidizing loosing 2e- and forms Cl2 gas. Cu2+ formed on anode dissolves into solution migrating and regains 2e- on the cathode to from Cu metallic copper. This causes it to be deposited onto the cathode. over time the anode will fully oxidize away and reform onto the cathode. Na+ gains e- from negative cathode terminal to then form NaOH from H+ and OH- ions naturally in the water. By all means though corrections are more than welcome if you chemistry better or have anything to add.
It takes longer than 3 days I put a 3s 5400mah battery in salt water and after 3 days it was still releasing bubbles from the cut cable. Then I punctured it and still had a reacton. A small one but there was still a small charge and there was a lil bit of smoke and such
I have a lipo battery like that . Not as swollen as yours but you can feel a slight swell when held in hand. My question is how do I know if it's still good to keep using . I bought it new about 4 years ago and used it a few times. Than I put it storage. Just decided to fly my drone today and noticed battery slight puffy. How do know if it's still safe to use ??
I did this on my first try on my Traxxas 6700 4s lipo battery, but if I leave it outside, and my tio tells me not to let it outside while the sun shines, and my house has no large spots to disposal my lipo battery if it puffed or not used
This will bring the charge down, but the saver way is to use a light. The green is copper from the wire, salt water reaction, and polarity interaction. Not the best way to discharge. If you have LiPO inside, keep them in a metal box and a cool dry location. Do not overcharge, do not over deplete the charge.
Do you keep your lipo's in your house I'm getting into the hobby and the only place I have to keep the batts are in my house I live in Maine and it's to cold out side any tips would be greatly appreciated tha ks
I tried it 2 weeks later still charged how can water get in to neutralize it if it's full of compressed gas, connect it to a low wattage bulb take it to zero volts then leave it connected 24 hrs check it is zero when disconnected twist the red and black together now it's safe to dispose of.
fireworks! ..and that's how you unsafely discharge a lipo! ..from our point of view we saw that coming a mile away! "don't cut the black and red...don't cut the red!
As said below , Battery still uncontaminated , just discharged thru the salt water making clorine water mix just like science lab ,yumm.... ,don,t drink!!! large power resistor with high enough value to limit current less messy .
I disagree, to fix a puffy lipo you can poke it with a pin and it will deflate Just joking, but on a serious note I've had lipos 4+ years old still going strong... what made this one puff after only a year man
Not a solution. This is electrolysis, & salt water is a poor conductor. At best, this method will only corrode the leads enough to keep them from shorting. It should be put under load until discharged. And while the water isn't harmful, the battery still is & should be recycled.
i don't think anything was extracted. what you did was an accelerated corrosion (that's the green stuff...same as can be found on unprotected automotive battery terminals), which shorted the battery and drained it to 0 volts. All toxic components are still inside.
STOP recommending this method, it does NOTHING. The salty water is not conductive enough to discharge them. Better hook the battery to a small DC motor or a light bulb to discharge it completely.
LØx Shansway I have one to. I’ve been using it to and it works just fine. I just don’t want this thing to blow up she catch fire one day. Your saying that it didn’t burn, mine has t either so....🤷🏿♂️
LØx Shansway Exactly. Iv'e had over 5 that have been swollen up for over 8 years. They are no more of a fire hazard than any other LiPo. Those are facts. I laugh how peop[e will pass along what they've heard as though it's fact. Ha ha
@@joshgreer1468i know it's been 4 years so I don't expect an answer, but if anyone does happen to read this, how did your swollen batteries from that time end up? Very keen to hear if they continued to hold up or if any of y'all had any combustion. :)
