Reply to comment by astrangeparrot in A breakthrough in electric vehicle battery design has enabled a 10-minute charge time for a typical EV battery. The record-breaking combination of a shorter charge time and more energy acquired for longer travel range was announced today by Wagamaga

Sounds like a key breakthrough is the nickel foil, which self regulates the temp and reactivity of the battery.

I am unconvinced by just an article that a few grams of nickel can regulate the temperature generated by 50~ish mWh being shot into a box of 18650s in the space of 10 minutes, but I do hope that I'm wrong.

The heat will be towed outside of the environment.

Well I’m not here to convince anyone but it does state that from what I read, as well as saying the nickel foil cools from the inside somehow vs outside, as is the usual approach, so it is fundamentally different at least.

Oh, certainly. I've grown sadly skeptical of advances in the tech sector when it comes to batteries. The steam engine and internal combustion engines have had slow, steady, measured progress over the years, and batteries... Well... We got electric cars to work, mostly.

In 20 more years we might be there for everyone. That's the dream.
