Planes can absolutely be electrified. We just need to find a more dense energy storage medium than Li-ion/Li-poly batteries. Lithium-air batteries have energy density comparable to gasoline, so they might work if we can figure out how to make them rechargeable. A fuel cell could potentially work as well.
