That's pretty impressive, but if they can't figure out how to mass produce them cost effectively, then it's pointless. Most of these battery breakthroughs never make it out of the lab.

That is not entirely true. Battery capacity has increased significantly in recent years due to these constant developments.
Battery capacity of established chemistries*
Nope! Lithium polymer batteries are substantially different from lithium ion. Each generation of lithium batteries is a pretty unique chemistry, the only thing that stays constant is the use of lithium as the cathode. Electrolyte, anode, and interface chemistry actually progresses pretty quickly.
Also, for drastically different battery chemistries which have been commercialized, see sodium ion batteries, and to a lesser extent NaS/ZEBRA batteries.
**edit: typo
Could this energy density provide a good enough Wh/kg ratio for general/leisure aviation?
