So I am stockpiling hundreds of Sanyo 18650 cells just because I have a constant supply of cells that were removed from service on a time basis, rather than a failure basis. I plan to use these cells in a land speed race car or motorcycle project. In planning the battery, I would like some sort of fire suppression system and, since the electrolyte supplies its own O2, I am wondering why I couldn't design a bladder full of DI water to rest atop the battery. If one cell were to "blow torch," it would quickly burn a hole in the bladder and self-extinguish with DI water (or at least cool the pack to help avoid a chain reaction burn). Since DI water is in the Mega ohm range, I don't foresee the whole pack shorting out by being drenched with DI water. Am I way off-base in this assumption?
PS: I realize this is posted in the Solar & Wind section; I do plan on charging this system with solar panels while on the salt flats. The concept is to prove that you can go 200mph using the sun's energy instead of burning fossil fuels.
