Do LiFePO4 instead. Nothing is fireproof but those are pretty tame.

The reason LiFePO4 is safer than higher voltage Liion is because it has less energy per volume. But even LiFePO4 can catch fire if punctured.[1] Although often incorrectly claimed to be, LiFePO4 secondary cells are not "intrinsically safe," like NiMH secondary cells are.
