That's called a fuel cell. Runs on hydrogen.Another possible alternative to help push electric cars would be some sort of fluid battery solution that can be drained and replaced at refilling stations.
If you're talking about an actual electrolyte, that would actually greatly increase mass because you'd be going back to the older wet-cell battery technology, such as lead-acid, and that not only weighs more you then have the issue of having a highly toxic and hazardous chemical in vast quantities in the vehicle with you.
Battery tech just isn't there for electric vehicles. Never has been and doesn't, at this point, look like it will ever be. That elusive super-battery continues to be 'just 10 years away' and has been so as long as I have been alive.
