Good news!

@johncarlosbaez
I don't know if you have but if you haven't, I suggest you look into Chinese electric cars, they're so much better and it's a crime that I can't buy one of them in the US. They're cheaper and better(or at least, I believe so).

Even though America says they love competition... they don't actually "love" competition and free market lol but anyways, if those cars were available in america and people didn't have "Chinese derangement syndrome", those cars will DOMINATE.

This video is an example of what I'm talking about, I believe it's a crime by the government that the American people aren't even given the opportunity to buy this car, I believe it's anti free market and thus, in essence anti American values. The US government stopped serving the American people, and started serving corporations. Also corporations today are too focused on making profits.

But anyways, I went on a tangent there. you can find the video below:

I'm trying to figure out how the new solid-state batteries work. So far I'm getting this:

They use a solid lithium sulfide-based electrolyte - a glassy ceramic material made using Li₂S and P₂S₅, which combine to form various lithium thiophosphates like Li₃PS₄, Li₇P₃S₁₁ and Li₄P₂S₆. The resulting sulfide glass has a high conductivity for Li⁺ ions, comparable to liquid electrolytes. The Li⁺ ions hop through the disordered sulfide lattice via vacancies and interstitial sites.

The hard part: the glassy material should be soft enough to keep contact with the electrodes as it expands and contracts during charge-discharge cycles, and not crack. Toyota claims to have solved this problem.

(Nerdy nitpick: this article says the new car's range is 621 miles. Can you guess why they give such a precise figure?)

I can't afford this car at the moment LOL but I am justified in my critique cause in the future if I do have the money to purchase, I won't be able to do so unfortunately but also there is a lot of bullshit/strings that comes with owning a car in the US and probably most places.

In my ideal world, people won't need to drive, it will all be self driving and free, people will only own cars for "fun".

@isocat - no, because it's the NOT SUFFICIENTLY ROUNDED conversion. 1000 kilometers has one significant digit - it's clearly a rough estimate. Claiming the car goes 621 miles is bullshit. Does it always conk out on mile 622?

@arsatiki - I may be overoptimistic, but things are looking better now in various ways:

"EVs with semi-solid-state batteries are already rolling out in China, albeit in small numbers. Customers can buy and drive them today, thanks to early adopters such as Nio and the state-backed SAIC Motors that invested in the tech early. In the West, Mercedes-Benz and BMW are testing solid-state batteries, and Stellantis is planning to begin trials next year.

Japanese and Korean automakers are also working on this tech, but they’ve been tight-lipped about their plans. In 2022, Nikkei reported that Toyota held the highest number of solid-state battery patents, followed by Panasonic and Idemitsu."

If they are a responsible ethical company then it's probably an under estimation. The same way bridges have "limits", it probably could handle more but that's the "safe" zone. I believe it's better to give lower rough estimates that is false when real capability is higher than the vice versa. But also with these companies, it could all just be marketing schemes. imma be honest, 1000 kilometers looks better to the eye than 621 miles. Also, it could all just be bullshit.

@johncarlosbaez @isocat
even though, I'm "American" and live in "America". I personally don't use the American metric system cause it makes my calculations look ugly. I love America independence but America is too "independent", America could've just adopted the metric system and life would have been easier for everyone, there wouldn't be a need for "translation". it's literally unnecessary, it just leads to unnecessary confusion when the world is already complicated, I think it's "stupid".
