Recharge in seconds with nano-molecule technology

[voyager]

Electric cars could soon be charged up in as much time as it takes to put fuel in a petrol car after scientists develop a new energy storage system. A group of chemists from the University of Glasgow has developed a new ‘flow battery’ system which utilises nano-molecules to be able to store either electric power or hydrogen gas. It will be based on the design of a nanoscale battery molecule and it will be able to release power on demand as either electric or hydrogen to power a car.

Nano-molecules could be contained in a pumpable liquid and could see the new liquid replace the old in seconds. According to the report published in the journal Nature Chemistry, when a concentrated liquid contains nano-molecules, the amount of energy it can store increases by almost 10 times.


Battery breakthrough could recharge electric cars in SECONDS

breakthrough number 1001.

Once it makes it into actual purchasable products I´ll be impressed, until then...meh.

Just conveying what a few Brits came up with. Can't comment on the 'invention' itself.

 

[JohnSnowNW]

My Alma mater. Certainly an interesting idea.

So this is basically a battery swap using liquid batteries?

 

[SSonnentag]

Not enough information. What is the fluid made of? Can the battery still be charged at home? Safety? Toxicity? I don't care how quickly a fluid swap would be; if I can't charge at home I'm not interested.

Ahh, the future of mankind is saved. Again.

This will never happen. Even if the battery tech is there, you need insane amounts of shore power.

If you want to charge a 100 kWh pack in 1 minute you need 6 MW of power for 1 minute. That is an insane amount of power that is not available on every street corner. Infrastructure costs to supply 6 MW will be substantial. Adding or dropping 6 MW of load on the grid will have impact on grid stability. Some indicate 6 MW is enough to supply 6000 households, that is a small village.

Tesla's largest Supercharger station, a 50-stall station in China will only do 3 MW when 50 cars are charging (25 stalls * 120 kW).

You will also need a cable the size of your upper legs to transfer that amount of power.

Lets say we want to keep the same cable diameter. Tesla currently pushed about 250 Amps through SuC cables.
6 MW / 250 amps = 250 kV = 250.000 volt!

These are voltages and amps that you do _not_ want to be handled by individuals or running through a car. Also, transferring 250 kV through a cable will require additional insulation, thus the cable will be thicker anyway. The connector/plug will also have to be considerably bigger to isolate the poles (if they are too close to each other and the voltage is too high you will get arcing)

And i'm just talking about 1 minute. Thread subject talks about seconds.

This might be nice for your mobile phone or your laptop, but this will never happen with cars. It is too dangerous. So "filling up your EV" like an ICE in 1 minute or two will never happen.
