Or you rethink completely the problem, and beam the energy to the plane.
This is more on an engineering challenge, unlike much better batteries which will require a fundamental scientific breaktrough.

It's an absolutely huge engineering challenge, but at least it doesn't require a discovery worth of the Nobel prize in chemistry (which I guess much improved batteries would warrant).
Battery energy density is steadily improving every year. The 2019 Nobel Prize in Chemistry went to the inventors of the lithium ion battery.
