Structural batteries were supposed to be the solution where the density wasn't so important. I don't really have a good understanding of the ration of fuel weight to structural weight in existing aircraft though.

casing is around 25% of the mass of a cylindrical cell, with the rest being actual battery bits that can't have any stresses applied. is 25% weight saving that significant?
