Here's a half-baked idea. The big problem with many next-generation electric cells like lithium-airs is that they have a short lifespan, right? But aircraft, unlike domestic cars, already have a fairly intensive maintenance schedule. Might it be feasible to just completely replace the batteries a few times every year? Obviously the manufacturing cost of the batteries, net of whatever you recover from recycling them, would have to be not too crushing.
