I'm pretty sure the casings are there for fire isolation

Yes but couldn't you have a casing that holds a dozen cells instead of a casing on each individual cell?

If a cell burns it is going to take out its neighbors anyway.

Or they could start to do something similar to LiFePo4 which will not burn.
