it sounds like more akin to an electrolyte capacitor than a battery.

It is.  One version developed in Australia uses the same compound on
either of the membranes, (vanadium) which minimizes some the problems
encountered by commonly used membrane materials.  
One of the coolest aspects of this type of battery, is that the fluids
can be charged independantly of the battery, and when you battery is
low... just fill'er up with freshly charged fluids, exchanging you own
depleted (but ready for recharge) fluids, costing you, in theory, only
the energy and the cost of the service.
So, if you want a 300 mile car, you carry more fluid.. or stop and
refill as in a standard vehicle.

Couldn't tell if the "100 mile" hybrid was using the Vanadium redox
battery, but that battery is not a capacitor, it does not store a "static
charge". It is more like a fuel cell, storing the charge in chemical
reactions in the electrolyte, which can be pumped and stored in tanks, thus
storing the power nearly indefinitely. The storage capacity can be
increased simply by using larger tanks and more of the special Vanadium
electrolyte.
