"there is no battery available anywhere today that can cycle over 10,000 times to depth of discharge down to 20 percent as VRB can...none."
compressed air in metal tanks can.. i know it's small scale and not a battery, but it does function as one in this circumstance.
points 7 and 8 are the most pertinent.

Advantages of compressed air as an energy vector
A vehicle powered by compressed air offers a lot of advantages in comparison with a normal combustion engine or an electrical motor.
The idea of using compressed air as an energy vector can, for example, also by applied to a hybrid vehicle, with cylinders functioning on compressed air and an additional battery working on electricity, creating a vehicle powered solely on electrical-pneumatic propulsion.
Advantages of vehicles powered by compressed air:
1. The costs involved to compress the air to be used in a vehicle are inferior to the costs involved with a normal combustion engine.
2. Air is abundant, economical, transportable, storable and, most importantly, nonpolluting.
3. The technology involved with compressed air reduces the production costs of vehicles with 20% because it is not necessary to assemble a refrigeration system, a fuel tank, spark plugs or silencers.
4. Air itself is not flammable.
5. The mechanical design of the motor is simple and robust
It does not suffer from corrosion damage resulting from the battery.
6. Less manufacturing and maintenance costs.
7. The tanks used in an air compressed motor can be discarded or recycled with less contamination than batteries.
8. The tanks used in a compressed air motor have a longer lifespan in comparison with batteries, which, after a while suffer from a reduction in performance. |
