Structural batteries would be the worst possible "advancement" we could make in that particular arena. First, if the battery is fully incorporated with the structure, you have to discard the whole product when the batteries stop holding a charge. I hate the environment as much as the next guy, but that seems a bit excessive. Second, if you're using these in, say, a car, what happens when that car gets in an accident? What would have been minor, potentially only even cosmetic damage, now requires a full rebuild of the vehicle...to the point that most people will likely throw them away after one accident.
