Weight reduction using batteries in airplanes is nowhere on the horizon. Compared to ground vehicle drive trains, jet engines have a great power to weight ratio, and they use no transmission. Replacing a modern jet with a motor and propeller is in itself a step backward.

On the other hand, airplanes spend a lot of time above the clouds and have a lot of surface area, so perhaps solar panels could provide a measurable range boost on day flights. But I kind of doubt it; solar panels have a terrible power to weight ratio.

This is dumb to even think about until batteries improve dramatically. In fact I suspect it may never actually work, because as technology progresses, it will become viable to manufacture carbon neutral fuel for use in airplanes.
