Not to mention that jet planes routinely take off heavier than their max safe landing weight today too, relying on the weight reduction of consuming the fuel to return the plane to a safe landing weight again while enjoying the extra range afforded. This trick doesn't work well with batteries either.
There isn't any battery technology on the horizon that would lead to practical airliners.
You could do it with a ground effect plane for inland sea jaunts, like Seattle to Victoria. If you can float, then you don’t technically need a huge reserve like is normally needed.
