To be fair, you probably don't need to achieve the same energy density as hydrocarbons for the vast majority of flights. Yeah, non stop flights from canberra to stockholm or similar distances will probably (at least in our lifetime) always depend on high density fuel. But I can definitely see a near future where 100% of flights on the same continent can be run 100% electric. The energy conversion to electricity is most efficient in power plants and solar, so making sure that as many flights as possible are powered by those sources is for sure something that is preferable to anything we are doing today.
Also, those batteries - after having outlived their usefulness for aviation because of capacity loss - have still a long live in front of them as energy storage for the energy net itself, where a loss of 20% capacity isn't a dealbreaker. Since the largest issue nowadays isn't generation of power, but storage of the same for covering nights, building high capacity batteries is a good thing regardless of initial usage.
Edit: WHY the fuck aren't airports already plastered full of solar cells?
