I suspect they may have a higher density and therefore seem better in comparison to older batteries.

I looked at a minute, reacted on the fact that they use nonstandard measurements and went for info on the web instead.

Not sure about the 1000 charge cycles. That's only three years if you charge it everyday like you do with a phone.
People have got into the habit of charging frequently whenever they can.

...but if you can get 1000km on a single charge, you're not going to be recharging every day.

This is where you run into other issues. Most people will be try to charge their vehicles at home. To charge a battery of any type to capacity to last 1000km will require a significant amount of electricity from you home supply which will not generally be rated for that capacity. Hence the charging will generally be over many nights with driving during the day. Unless of course you make major change to your power supply. (and the utility company will play a large part in deciding that)
Hence it all depends on how the battery will handle half, quarter charges (or whatever) on a frequent bases.

yeah I remember when I got my latest phone,
went for days on each of the first few charges
... few months later already needing daily charging.
same as the phone before, and the one before that ...
oh, and has your phone, (even when new) achieved it's claimed charge lifetime?
"1000km" - IN THE LAB = real-life maybe (being generous) 700km on the first few charges
after 6 months you'll be doing well to get 300km
and 3 2 years, yeah about then: calling AA for a tow home from the shops after all-night charging.

When I go vacationing in North Norway, I have several times been driving 1000+ km a day. I also had a vacation home in South Norway, 900 km driving, and I often did that in one setting.
I guess Norway is the country with the highest electric car density - more than half of all new cars sold are electric. We have been using so much electricity in this country, for heating, hot water, light, cooking, ... everything. Now also for electric cars. My main fuse is 3*63A (although I have never been close to needing that!)
If you buy an electric car, you install a charger with minimum 7 kW charging effect. Most established car models cannot handle more than 11 kW, so many el-car owners stop at that, but a fair share go for 22 kW chargers - they are not that much more expensive, and future-proof even if your current car cannot utilize it. Then you can fully charge a 100 kWh battery in less than a night, even if charging is slower as the battery fills up.
I do not have an electric car yet (but I do have an electric motorcycle). Yet, when I put up a new free-standing garage this summer, I plan to install an 11 kW charger, for future proofing, and for el-car friends visiting me.
(We have a somewhat special approach to electricity in Norway. When I bought a new cooking store, with two gas burners and two electric induction hotplates, everybody laughed at me. Gas? What do you want that for? I even have a couple portable 4.5 kW propane heaters, both because they are great boosters when I come home to an ice cold house, and in case we have a power outage. But Norwegians don't see the point of it. Electricity is everything.)

That's three times the estimated life of a standard lithium battery (something to do with dendrites if I watched that video right) and if you can get 1000Km from a single charge then you can break the cycle of daily charging and nearly eliminate "Range anxiety" which makes you stop and charge far too early.
Look at it this way: my car (a diesel Mercedes) will happily get around 1000Km per tank on a long run - so if I'm going a long way I make sure it's full the previous day. Even the "best" electric cars are touted by their manufacturers as getting 400Km, and once you are out of the big cities the distance between "fast chargers" is still pretty major: only 1,500 of 'em (with space to charge 3,400 vehicles) in the whole of the UK - and they take 1hr to give you another 400 km, so chances are you'll have to wait quite a while for a free one. Compare that to a standard "gas station" where 1000Km will fill in three minutes or less and they are everywhere.
Back in Feb, I had to take Herself to her sister's funeral - and I'd have had to stop for a charge at least twice, probably three times on the round trip. That would have added three hours to the trip, which would have meant leaving an hour earlier, and that would have meant standing traffic for an hour or more as it would have been rush hour. Same on the way back! We didn't have to stop for anything in the current car ...
How often do I "charge" the merc? Once a month - and if for that I had to drive 50Km to the nearest fast charge station and wait around an hour while it charges then yes, I could work round that as they will be more available in future. But when that means taking 100Km out of a 400Km range and doing it three or four extra times a month ... No. Electric isn't ready yet.
That's why this is potentially so exciting - it could bring electric cars up to a "level playing field" with fossil fuels - and if the battery has to be changed every 1,000,000Km then so be it - most fossil fueled cars will need something major done by that point anyway!

As long as "days" is still the unit of time used to measure this, I'm not impressed.
And no, you can't use "sevenths of a week".

I did some looking into this yesterday.
It's not total bull, but the biggest achievement seems to be that they have managed to squeeze the batteries into using less space.
The energy density seems to be only a bit higher than NCA batteries (what Tesla uses).
The new battery has a capacity of 205 mAh/g while an NCA is up to 200 mAh/g. It's unclear what the nominal voltage is, but I doubt the difference is big.
So to achieve a range of 1000 km the cars might remain the same size but become much heavier. And probably as much more expensive.

And is the battery fully + easily + cheaply recyclable at end-of-life? Is it using quantities of rare minerals? Is the extraction and manufacturing process highly polluting / energy intensive?
These are the considerations that have stopped me switching to electric car so far (that, and the fact that my 14-year old petrol Skoda has done 120,000 miles but is still going strong, performing more efficiently than many new petrol cars, still comfortable, if a little "care-worn"). I don't drive a huge amount; mainly local trips of under 50 miles in total, plus a fortnightly weekend 150 miles away. Many electric cars are now quite capable of meeting that sort of usage, but while driving them may be a cleaner, greener option taking the whole car / battery life cycle into account it's probably not - especially if it means scrapping a perfectly good car.

I wonder what the May revolutionary battery technology will be.

Around here, people started hoarding tuits a month ago. You may still find a few rectangular ones, but the round ones have been out of stock for several weeks.

Well, there is a British Standard Finger.
You use it for poking into holes ... to see if you can touch anything dangerous.
I became aware of this when my PM and I took a mains powered cobbled together prototype (housed in a bunch of cardboard boxes with slots cut for ventilation) into a major company headquarters. We had to make the slots thin enough that the BSF couldn't hit the mains components (but nobody cared about the rather larger risk of the whole thing catching fire - why did you think it needed ventilation in the first place? )
