It's also worth noting that the range of an airliner depends heavily on the fact that it becomes lighter en route through burning fuel. At takeoff, nearly half the mass of the aircraft can be fuel. Batteries don't provide that kind of mass reduction as they discharge, which means long-range flight using only batteries as a power source is rather unlikely.
