(in an application where the mechanical protection might be important.) But the technology is very similar to li-ion, and I'm not convinced that they're fundamentally "less tame." (likewise, the last laptop battery pack I stripped for it's cells happened to have LiPo cells rather than li-ion cells, so it's hard to tell which is which...)
