Israelis are going through all the grief that we could read in memoirs of Germans in the 1930s, while Germans keep pretending like everything is fine in Israel and all the depravity against Palestinians on display is justified.
It isn't. All decent people know it's not.
1/ Just sadness and mind-numbing grief today, of the most selfish kind. Sadness for my country and my society, sick and hollowed out, but still my home, my language, my past and future. Anger and shame are always there, but today it is sadness and the grief for the win. --->

Und jetzt nochmal auf Deutsch.
Da ist der erste Prototyp für Elektroautos ohne Lithium. Es war seit 2 Jahren absehbar, jetzt ist es da. Normalerweise hat das Auto 20 oder 30 kWh, mit Natrium Akku hat es 25 kWh ... und lässt sich in 10 Minuten von 20% auf 70% laden.

I have not merely told you so, I couldn't shut up about it for years.
It's an EV with sodium ion batteries. The capacity of 25 kWh is not huge, but the regular capacity of this model with lithium is either 20 kWh or 31 kWh.
But this one is faster charging and better in winter.

The pack energy density of 120 Wh/kg (cells have 140Wh/kg) is just a sliver below the 2020 Tesla Model 3 LFP pack, which had 125 Wh/kg.
If you build the same 54 kWh pack with sodium, it would weigh 450kg, just 18 kg more than the LFP pack. But it can charge to 80% in 15 minutes.

And there we go. First EVs to use CATLs sodium ion batteries.
It's not surprising. The energy density (both mass and volume) is comparable to 2021 Tesla Model 3 LFP battery packs.
Our first sodium-ion battery will power the Chery EV models. The award-winning technology breaks the bottleneck of limited raw materials and provides a cost-effective solution.

Tesla fans will have to be strong over this one. But the 4680, as a cylindrical cell, simply isn't the most volume or weight efficient form factor. It wastes space and mass. It remains to be seen if increased stiffness of the 4680 is enough of an advantage.

OHB is selling its 57% stake in Rocketfactory Augsburg. I think it's fair to say that the company is well on its way out. (It was the pet project of OHB boss Marco Fuchs, as I've been told independently by several company insiders over the years.)
Nach dem unsäglichen Interview mit den juristischen Firmengründern vor 2 Jahren war es längst absehbar, aber nun ist das Ende der Rocketfactory Augsburg noch ein ganzes Stück näher gerückt. Die Firma war praktisch ein Privatprojekt des OHB-Chefs. (vgl. Richard Branson)

You can now buy sodium ion batteries on Alibaba from small, completely unknown companies. Anything from 18650 to 46145 cylindrical to large 173*71*204mm prismatic cells. Sold for ~$120-$140 per kWh. They do seem to ship and actually arrive, even in Germany.

Just $37/kWh material cost for LFP batteries. Lithium, graphite, copper and the processing costs for sub-micron sized LFP are probably a substantial part of that.
Lithium ion battery px continue to plunge as BOM for LFP battery has dropped to 266 RMB/kwh
Sub $50/kwh battery should be common
Global production of LFP & NCM was abt 120Gwh in May
About 40Gwh installed in Chinese EVs, so significant qty will be for ESS as renewable buildup

The only real miss today was failure to reignite the Raptor engines (as failures in Super Heavy and not attempted in Starship), but this did not cause any disruption in the rest of the test program. So, it's basically a success. You can learn much less from fireballs.
Starship burnt up. Super Heavy crashed. It’s easy to see failure. If you want, go ahead. But this is failing forward at its finest. One of SpaceX’s secret sauces is an acceptance of failure as a means to an end. We are much nearer that end, rapid and fully reusable launch, today.

Sodium ion batteries (2020 to today):

CATL released a PR video for their Qilin pack. Suitably monumental. 72% pack efficiency compared to the 40-45% or so in recent years is a serious achievement. Unless there are major quality issues, this will shake up the industry as much as the first CTP.

Makes me wonder why they don't use heat pumps to increase the temperature. It will add heat to be rejected, but should increase heat rejection much more. (Could help to run instruments generating more heat when heat pumps are running. Needs a lot of redundancy though.)

And that's why sodium ion batteries must become the mainstay of the battery industry. No lithium, no cobalt, no nickel, no copper.
They need no rare metal ores that must be mined at low concentration, causing all this destruction. And they are good enough for the job.
To manufacture each EV battery, you must process
25,000 pounds of brine for the lithium
30,000 pounds of ore for the cobalt
5,000 pounds of ore for the nickel, 25,000 pounds of ore for copper
Diging up 500,000 pounds of the earth's crust
For just - one - battery.

New sodium ion batteries everywhere, from companies you (or at least I) never heard of.
Don't tell me it's just a fad. With the price gouging of the lithium industry, this is the only viable battery technology going forward where cost and reliability of supply are important.

That $74/kWh figure includes (with the discount!) about $20/kWh worth of lithium carbonate (about 700 grams).
Which should tell you how cheap it has become to make battery cells these days.
