Batteries store energy. I don't know what the limit is in some given volume. But I doubt we can exponentially just cram more and more electrons into a given space in the same way that in computers we cut the required number of electrons in half a couple of dozen times.

A suitcase room-temperature-fusion reactor might do the job of giving a car 10,000-mile range.

Note, however, that this is unlikely to come about by developments in battery technology.
