Most of the ones I've worked on were ones where the battery had already started splitting the case. They would have had plenty of air. I'm sure our battery fire is an extreme circumstance, but I take much more precautions after that happened. They immediately get taken to a metal bin out back and we deal with them later.

Additionally lithium based batteries don’t give a Flying F about oxygen availability.
When the reaction starts and the combustion goes off, a by-product of lithium when the anode and cathode break through the separator and start directly reacting is…. oxygen. Which is why they will burn submerged in water alone or even with no other oxygen sources present.

This partly why they are so difficult to deal with and why they limit sizes of batteries being shipped by air.
