Japanese firm believes it could make a solid-state battery with a range of 745 miles that charges in 10 minutes

    This sounds more like a capacitor than a battery. Also: that’s a lot of current to dump into an energy storage device in a short period of time. There’s no way you’re going to be able to do that at home without major overhauls to the last mile of the electrical grid. (I also question whether dedicated charging stations will be able to do it either, without some sort of serious on-site energy storage/buffer to moderate the spikes in current draw to the broader electrical grid.)

      No. It’s a battery not a capacitor. And no, you won’t do home charging at 100s of kilowatts. That’s totally pointless. Fast charging is for road trips, when you want short charging breaks. If you could charge a 100 KWh battery at a continuous 350 KW, you’d be done in less than 20 minutes from 0 to full. 350 is about the maximum we can do today and i don’t see that growing much higher. Those huge charging speeds being thrown around in these articles are not practically relevant.

      Charging at home generally doesn’t have to be fast though, only when you’re on the go would you need extra fast charging. With newer generation batteries (like sulfur and lithium based batteries) faster charging will be easier but dedicated charging stations probably need some adjustment indeed.
