I didn’t get the impression that this design had higher density, just that it lasted longer. Sure, that is nice, instead of replacing your PV/wind turbine batteries every 5 years you can do it every 10 years, but if they cost twice as much that isn’t terribly valuable.
Still, any improvement in batteries is something to be happy about.
