But now Samsung SDI is teaming up with BMW and US-based battery company Solid Power for their own effort at commercializing all-solid-state EV batteries "in what's expected to be a trilateral powerhouse."
> BMW and Solid Power have been working together to develop the next-gen battery tech since 2022... Under the new agreement signed this week, Samsung will supply all-solid-state battery cells. Samsung will use Solid Power's [4]Sulfide-Based Solid Electrolyte solution , while BMW will develop the battery pack and modules.
>
> The strategic alliance aims to take the lead in commercializing all-solid-state batteries (ASSBs). Together, they've created a real-world system for producing ASSB cells, pooling their expertise in batteries, automaking, and materials to bring it closer to mass production. Solid Power's electrolyte solution is designed for stability and maximum conductivity. By teaming up with BMW and Samsung SDI, the company said it aims to bring all-solid-state batteries closer to widespread adoption.
"By pooling resources, BMW, Samsung SDI, and Solid Power have a real shot..." argues Electrek .

"introduce". This means that actual use is going to they are aiming to work out production snags in 2028 before scaling up in 2029. 2030 is when you should expect these to be generally available.
Engineering battery tech is like microfabrication: it takes time because mistakes can be expensive. They will only rush the process if they fear someone will beat them to the market.

Duh. BMW and Toyota. They have squandered years of development time. BYD is producing solid-state batteries in small batches for engineering tests, and they're scaling up the production now. They are expecting production rollout around 2027, with gradual scaling over the next several years.
At the same time, CATL is already producing LFPs with 200Wh/kg system density, enough for a 400-mile range on a typical EV ( [1]https://www.catl.com/en/news/6... [catl.com] ). And the sodium-ion cells are at around 140Wh/kg, comparab

Another important use is airplanes. For cars, current batteries are "good enough", though higher density would still be good. For airplanes, current batteries are just barely usable for very short flights. Doubling the density would be a big deal.

Chinese have reduced costs, and as for self driving cars, I think attitudes need to change such that the standard is not perfection, but better than most people. The attitude now is that if a death occurs with a self driving car, then everybody gets a hair up their but, however, if a drunk kills someone, eh, shit happens.

They end up in prison, convicted of manslaughter. The response when Uber killed someone was to blame the person they killed, the observer in the car and anyone but the corporation that decided to turn off the safety features because it was interfering with their testing. The problem is that the folks operating self-driving vehicles are all drunk on profit. And there is no incentive for them to sober up.

Perhaps you are correct. My personal belief is that if Corporations consider themselves as "People", with rights and all of that, then if a Corporation willfully kills someone, then their CEO should stand trial for murder. As for "drunk on profit", I have yet to see a self-driving venture make a profit. They just get gobs of money dropped on them from Monopolists and Oligarchs in the hope... of someday.. it works.

The executives take "profits" in the form of high bonuses they vote themselves no matter how badly things go. A failure they walk into another high paying job with bags of cash. A success and they vote themselves lots of share which increase rapidly and again they get bags of cash.

Chinese Solid-State Battery Breakthrough Powers 800-Mile Range Chinese automakers have introduced a new solid-state battery technology that offers double the energy density of current market models, potentially powering electric vehicles for 800 miles on a single charge. Solid-state batteries are safer and more stable than traditional lithium-ion batteries due to their solid electrolyte, enabling faster charging and eliminating fire hazards.

As an American, I think we have "protected" the domestic electric car companies enough. The Chinese made a product that is twice as good and half the cost while Musk is taking drugs and destroying our democracy. I think, Drop the Tariffs on the Chinese cars, let us have decent products and stop subsidizing assholes.
