Articles like these always assume charging time is just a problem of the battery. Charging a 70kwh car battery would require a 4.2 MW charging cable/site. In order to not melt normal cables the voltage would have to be quite high. Maybe with a static connector on the underside of the car, who knows.

PS: To clarify. THIS Article does mention those issues. Others LIKE these often don't.

The article covers that charging a vehicle at 10x the current Tesla speed would be difficult. Both from a cable and grid perspective.

Ironically it also points out this would like cause demand for fossil fuel peakers, making the car far less green.

Think of it this way: no passenger car EV today can make full use of a 350 kW CCS charger. If this battery can enable a flat charging curve at 350 kW, then it would only take 17 minutes to charge a 100 kWh battery from 0 to 100% state of charge.

I am reading the same 'new tech hype' articles again and again. Very prominent on battery tech. These articles create unjustified hype by focussing on a few promising test results under lab conditions with prototypes. What they fail to mention are all other factors that contribute to a succesful new technology. Like just as examples, scalability, robustness, promise of ease of mass production, raw compound price, safety as good or better then proven tech, compatibility with the market standard.

There were literally hundreds of exactly those articles I read or skimmed through in the past, none of them made it to mass market. It's almost as if there might be an underlying scam that produces these research hypes to grab investor money or something. Until the real problems are adressed, or looked at and then the research ceases.

I mean I really hope there are some leaps in battery technology soon, as many do, because it does not hold up at all to moore's law as it is kind of needed for mobile devices to progress as fast as silicon or other advancements. I just don't care for misleading articles anymore :)

This battery addresses those things:

I sincerely hope this one is finally not a semi-hoax and delivers. I won't get my hopes up so soon though.

On a side note, I don't want to argue over this, but just saying I found two points (compound prices, safety) addressed. It reads kinda like a lot of hype... What do you take from the articles, how this reasearch project is more promising or further down the road then the many promising looking projects before them that ended up failing? You don't see a pattern? This one is now different, how?

They're at the commercialisation stage now. They'll be selling them next year.

It seems that these batteries solve the problem they are supposed to cause (Taking too much power). If you can put these in a charger then they can pull whatever power they need from the grid over a long time, then dump all their charge into an electric car in no time when the car shows up. I can imagine some huge batteries sitting in a 250 MW "Filling" station that are slowly being filled from a grid power line at a couple megawatts.
