Electric car batteries with five-minute charging times produced

This development may be game changing.  It is for that reason that I bring this article to your attention.  The source is The Guardian, unfortunately not my favorite source. But the story is too good to ignore. A Google search on StoreDot gives quite a few other articles on the subject, including from Bloomberg, The Times of Israel and from the company, StoreDot, themselves.

StoreDot has already demonstrated its “extreme fast-charging” battery in phones, drones and scooters and the 1,000 batteries it has now produced are to showcase its technology to carmakers and other companies. Daimler, BP, Samsung and TDK have all invested in StoreDot, which has raised $130m to date and was named a Bloomberg New Energy Finance Pioneer in 2020.

The batteries can be fully charged in five minutes but this would require much higher-powered chargers than used today. Using available charging infrastructure, StoreDot is aiming to deliver 100 miles of charge to a car battery in five minutes in 2025.

In addition, StoreDot says

"...we are not releasing a lab prototype, we are releasing engineering samples from a mass production line. This demonstrates it is feasible and it’s commercially ready.”

I do not see any articles on this in Energy Central. No doubt there will be more.  I hope members will weigh in on the technology and its feasibility and costs. Obviously, if true, there are even longer range implications for battery storage.

Note: My apologies to Rafael Herzberg. I just saw this report from yesterday.

"...we are not releasing a lab prototype, we are releasing engineering samples from a mass production line. This demonstrates it is feasible and it’s commercially ready.”

This is what you want to hear as opposed to the early early stage hype, but it's SUCH a leap forward that I still can't help but remain skeptical. How is the tech able to jump to five minutes without making a pit stop at 10, 15 minute batteries first?

Matt, I'm skeptical too. Attempting to charge a standard 100-mile, 24kWh, Li-Ion battery in five minutes would require 288,000 watts of power.

Sure, it could be done using "only" 300 amps of current and 15 lbs of cable, at a voltage that would instantly electrocute any hapless driver who came between cable and car (960V). But with any standard Li-ion chemistry only about the first ~50% of capacity could be charged that quickly, anyway. It might be possible to charge a battery with twice the capacity halfway (?).

The road to EV storage is is a hype-way littered with broken dreams and bank accounts. Supercapacitor manufacturer EEStor has an almost comical record of bankruptcies, stock offerings, release dates, lawsuits, and production delays dating back to 2000. But the company, renamed FuelPositive, still exists...somehow. Read its history here.

I certainly don´t know if what StoreDot claims is true.  But you may get an inkling of what they are cooking here.

The magazine Driving is hosting a virtual panel discussion titled Driving into the Future with a panel they call "leading figures in the Canadian and global auto and energy industries." 

Among the panelists will be "Doron Myersdorf, CEO of Israeli start-up StoreDot, which claims to have invented the five-minute battery"

Should be interesting.
