Does anyone know if any battery can be just
covered with a thin layer of fiberglass & the attached cables potted
for external use.?
I was thinking maybe AGM or Glass matt, but I'm not
sure whether there are air voids in them.
If they have no air voids & don't off gass
possibly they are reasonably pressure resistant as they are.
Just read this on Wiki About Lithium
batteries.
Pure lithium is very reactive. It reacts vigorously with water to form lithium hydroxide and hydrogen gas is liberated. Thus a non-aqueous electrolyte is typically used, and a sealed container rigidly excludes water from the battery pack. Alan |
