I didn't see a number for cycle life. That'd be my biggest question here. You can charge in less than 7 minutes but how many times before performance (capacity) degrades?

I did not expect Nio's 5-minute battery swap technology to become obsolete this soon.

Saw this yesterday, did not expect the competition around Donut's batteries to heat up this much and this quickly.

Even the gravimetric density is fairly close, CATL's claim is 350 Wh/kg, compared to Donut's 400 Wh/kg.

The safety and durability (plus no lithium) prospects of Donut's V1 battery are still big though (if the thing is actually real).

> have a minute to plug in? Still sufficient to get from 10 to 35 percent state of charge.

Scaling that to something the size of an EV pack will require one massive cable/connector. Call it 5kw/h in 1/60 hours, thats 3000kw, at 700v thats still roughly 4000 amps. (Please correct my head math.) Charging one car could suck up more power than an entire neighbourhood. Say four or five chargers operating at once ... every roadside charging station will need its own electrical substation.

Neither article mentions what specs - voltage and kW - are used when doing this very fast charging.

Does anyone know? Assuming it's not just the current high-end spec of 800v? It matters because higher current requires heavier equipment to generate it and heavier cables too.
