You are forgetting that a dead battery weighs as much as a full one, whereas burned fuel doesn’t weigh anything. Any gains in power efficiency in the context of an airplane is likely to be offset by carrying extra battery weight all the time.

I guess the point is, some green energy source other than batteries is probably the solution for airplanes i.e. hydrogen/biofuels.
