LiitoKala = fire hazard

I tried this by sanding the spot first and putting the red paint as you can see, but it was hopeless, as the corrosion came from inside the cell to outside. There must have been a micro crack where the electrolyte came out.

Hooo i see, you are certainly right... maybe try to stop the leak if only a small amount of electrolyte as gone .....

A LiFePO4 cell will never experience thermal runaway. It's just not possible for that chemistry.

But leaking electrolyte is NOT good.

That cell was physically damaged when you put it into service. It should never have been put into service.

And...
I get beat up CONSTANTLY about LiFeP04 chemestry (charge density argiments) but then again I have used the press to run bolts through cells, shot them with a firearm, never once got a runaway from LiFeP04.

I also got crap on this forum about building in fire control when I built the last evolution of my system. C02 or Argon (cheap, commonly available) directly into the battery box...

Until you actually see how furious some batteries burn, and how hard they are to extinguish most people don't get the point...

Fully agree. Whoever has seen CO2 on a hot fire, will discard this option completely, it would just be a joke on a burning battery.

I have never seen a burning LiFePo4 myself, but there are some scary pix here in the forum, and they are certainly not fakes.

Damn, soo unlucky!
