This battery can be recharged and it can be refueled, both, just like any redox flow battery. The point is, when you are in a hurry you, you have the option to refuel quickly.
This is a strange company, combining a new type of redox flow battery with great specs with a superduper sportlimousine.
Who cares about the sportlimousine if anything they claim about the battery is true. We all know that electric motors are much better than ICE motors, that is not the big story about this 'Quant' car.
Just prove this nanoflowcell battery to the world,'Quant'.

Carbon (grahpene) and silicon are very common elements, so if the cathode problem has been solved I expect this technology to go mainstream soon after. How many recharge cycles reduce the capacity of this battery to 80% of the initial capacity? This would be a super car battery if combined with supercaps that also have graphene electrodes (in order to reduce peak currents and overheating).

New high-power Si–graphene composite electrode for Li-ion batteries
Northwestern Univ. researchers report on a new high-power Si–graphene composite anode material for Li-ion batteries in the journal Advanced Energy Materials. With current technology, the capabilities of a lithium-ion battery are limited in two ways: energy capacity is limited by the charge de...
And how does "Ricardo" come to this strange conclusion that the production of EV cars require more energy than ICE cars??? The ice motor is so much more complicated than an electric motor. Do they keep in mind that batteries can be recycled much more easily than any other part of the ice car?
Personally I don't believe the conclusion of "Ricardo". The UK elite (as well as the Dutch elite) are traditionally involved with oil (its their business).

Ricardo study finds electric and hybrid cars have a higher carbon footprint during production than conventional vehicles, but still offer a lower footprint over the full life cycle
Electric and hybrid cars generate more carbon emissions during their production than current conventional vehicles, but still have a lower carbon footprint overall, according to a new report prepared by Ricardo for, and in collaboration with, the expert membership of the UK’s Low Carbon Vehicle ...
Downscaling of size, but also reducing resistance, for instance the Loremo.com should get much more support.

Oxford University Study Finds Downscaling of Vehicle Size and Weight the Best Way to Reduce Transport GHG Emissions in the Short Term
An new study from the Smith School of Enterprise and the Environment at Oxford University suggests that best way to reduce transport greenhouse gas (GHG) emissions in the short term is a “drastic downscaling of both size and weight” of conventional gasoline and diesel cars. The study editor Sir...
BCG apparently has a crystal ball. Mass produced electric motors can be much cheaper than ICE motors, and this can compensate (for the time being) the extra expenses for batteries. The question of car economy is always complex and difficult, therefore focussing on just 1 negative aspect of the electric car is naive.

BCG Report Expects Battery Costs Will Constrain Widespread Market Adoption of Fully Electric Vehicles, Absent a Technology Breakthrough; Forecasts 26% of Major Market New Cars in 2020 To be Hybrid or Electric
As an example of cost direction, BCG forecasts that NCA cell and pack costs will decline 60-65% by 2020. Source: BCG. Click to enlarge. Although lithium-ion cell and pack costs are expected to fall sharply by 2020, they are unlikely to drop enough to support widespread adoption of fully elect...
It is a Sovjet Union communist style taxation that will discourage the Dutch people to travel, while it has nothing to do with wasting fuel.
The Dutch government and civil servants are like a waterhead: it grows and grows, has no intelligence, and costs more and more money. And guess who has to deliver the money?

Dutch Cabinet Approves Mileage Tax; In Effect in 2012 if Approved by Parliament
The Dutch Cabinet on Friday approved a new road tax bill that would eliminate the current motor vehicle tax and purchase tax and replace them with a charge per kilometer driven, starting in 2012 and increasing through 2018. The measure needs to be approved by the Dutch Parliament before becoming...
How to lie with statistics ...
- sediment cores register for many thousand of years the abundance of 'mosquito like midgets' (?? midget like mosquitos??).
- the resolution of the data is rather high, variations within 50 year periods are clearly visible.
Assume the shortest time interval to measure the abundance of 'midgets' (mosquitos?) is about 10 years, otherwise how to conclude there is a steep decline the last 50 to 60 years (??).
This means the researchers must have made 20000 samples and counted the midgets per sample. How accurate are each of these samples: is each sample really spanning about 10 years, or do older samples span many more years than accounted for by the researchers? Are they really counting 'midgets'; maybe the older samples contain many 'non-midgets' mistaken by the researchers for 'midgets' ?? even several midget species are mentioned: I really wonder if such observations can be made from very old ice-core samples.
Etc, etc, and many many more critical remarks can be made. The end-conclusion can be just another "mistake" (I am not speculating about political agendas and who is paying these researchers for what ever reason).
If you ask me, the research results are too wonderful to be true, so do the conclusions have any credibility?

Analysis of Arctic Sediments Show that Late 20th Century Warming is Unlike Natural Variation; “Unprecedented” Change
An analysis of sediment cores from an Arctic lake indicates that biological and chemical changes occurring there are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, according to a new study led by the University of Colorado at Boulder. A paper ...
