All sorts of problems with lithium-metal as we know it. A more benign version pitched by ZAF Energy is zinc-air. They inherit a few problems from pure metal electrodes (like dendrite growth) but not its thermal volatility. On the flipside, the performance increase will practically be not more than 2x that of lithium-ion.
ZAF had a very in-depth visit at Microsoft Research in June 2015. It is interesting to see the tribulations of a startup in commercializing technology that might become feasible but isn't quite yet and maybe never will. The 1h+ pre-sale meeting was taped [0] and I have an article in the writing about it [1].
