Lithium-air potentially has great energy density.
The theoretical limit is near that of gasoline. So there's been a lot of work in this area, going back decades. There are lots of problems. This is a possible solution to one of about six major problems with this chemistry. It's a step forward, though.
This research project used iridium, which is a problem. Total world production of iridium is only about 10 metric tons a year, and it sells for about $14,000/kg. A production technology is going to need something cheaper.
