The problem is this: chemical batteries (lithium for one) are already operating near their electrochemical theoretical limit. There aren't going to be any future batteries that are half the size and weight and twice the energy storage capacity for example. They may improve charging speed and other factors like that however.

Any serious improvements will come from a different technology if any. Running charging strips down the center of highways or something like that. Hydrogen is not likely to be the breakthru tech tho.
