CATL is the largest battery manufacturing company, supplying battery for almost every high-end devices.
CATL's primary product is NCM and followed by LFP. Their NCM development is more or less stalled at NCM811 while other leaders NCMs like LG (NCMA), SKI (NMCA) have moved out further. Also BYD's LFPs are known to be superior to CATL's for higher C-rates, faster charging, and safety.

Are these actual technical terms, or some sort of marketing speak?
Has something happened in this regard?
LFP is technically a bit less energy dense than some other chemistries but it has cost as its big advantage which is why it is the go to choice for a lot of the mass produced mid range EVs. A cheap fast charging battery is going to be quite nice as it makes fast charging stops less disruptive. Which means the utility of EVs with smaller batteries increases. So what if you have to take a 10 minute break every few hundred miles? Not a big deal. You'd probably do that anyway if you value your health and sanity.

> second-generation fast ion ring technology
> superconducting electrolyte formula
Can someone confirm those are proper names of some recent breakthroughs in LiFePO4 manufacturing or just some marketing technobabble?
If CATL had a roomtemperature superconducting electrolyte you'd know ;)
Probably exacerbated by internal/non-common terminology and maybe questionable translation.

Assuming 400km worth of charge needs maybe 60 kw/h of energy, to deliver that amount of energy in 10 minutes would require at least 360kw charger. Charging just a few cars simultaneously will require megawatts of power. I wonder what are the implications in terms of city infrastructure or investment costs to building charging stations for that.
The issue at the moment is that grids in a lot of places in the world can't keep up with the connection requests, and this is indeed mainly due to not being able to upgrade transmission capacity fast enough.
However, a household supply could supply substantially more with smarter software. Specifically, currently we rate power supplies with a decent safety margin for worst-case conditions.
However, your '100 amp' power supply can probably supply 200 amps on a freezing cold day (which helps keep cables cool). It can probably supply more than rated if your neighbours aren't using much (since your and your neighbours power connections may share cables).
If you or your neighbours have rooftop solar, thats power going the other direction, which cancels out some power use - allowing you to charge even faster.
If software could take these factors into account, we could get a lot more power to where it needs to be. Currently rules don't allow such things though.
Hyundai/Kia launched the EV6 with 10-80% charging in 17 minutes more than two years ago.
They then launched Hyundai IONIQ 6 with 10-80% at the 16 minute mark.
I guess we will be seeing 10-80% times get close to gas pump refill times in the near future.
You heard it first on HN.
