This is a growing concern. Chinese companies are accumulating substantial resources, and in some cases, near monopolies.
Meanwhile, IBM is apparently doing research on Li-air (or Li2O2) batteries.

Research is being done at University of St. Andrews
The St. Andrews work claims 1220 mAhg-1 are possible. For a 3V cell that is 3600 Wh/kg, or ~13MJ/kg, compared to 46 MJ/kg gasoline, remarkable. A practical battery w/ that density would tip over gasoline and diesel based transportation - cars, trucks, trains - all of it.
