You have to chase it down, following the link to electrek.co, but then it says: "the prototype cells house an energy density of 720 Wh/kg"
(of course, I'm just stating what is claimed, no idea how true)
Chase it down? It says 720 Wh/kg in the thumbnail image.
You're right, I didn't see it! I just saw a bunch of chinese writings, which I cannot read, so didn't bother trying to read even the only thing I could 😅
Yeah, I'm really sick of the hype train, so that was the only info I looked for. Honestly, I was a little surprised it was that easy to find, and that is still no guarantee it's accurate.
If that's true, 1300 mile range isn't the big deal. Going much over 400mi is pointless if we build proper charging infrastructure. Use wh/kg advancements to reduce weight, nor increase range.
The big thing is that we can build fully electric airplanes with that kind of wh/kg.
Big if, though. Batteries have been improving by 5-8% per year, and while we're not close to theoretical limits yet, this would represent an unprecedented leap all at once. That claim needs more to back it up than a press release.
Battery density has been improving steadily for the last three decades.
...
What's more, the Chinese market is both the leading producer and consumer of battery technology. So its weird to reflexively doubt that a Chinese firm would release a new higher-efficiency battery design.
Given that this is a prototype, its entirely unclear if the model is cost-efficient to mass manufacture or efficiently scalable based on available resources. But I'm hard pressed to discount the claim on its face simply because its got "China" in the headline.
I would instantly discount it based purely on not having third party verification or enough details for a third party to replicate.
Racist see China did something good and have to go out of their way to shit on China.
I think you are seeing this as racism when it is just some old good skepticism about a country that is famous for faking everything.
Maybe they really done what they say, or maybe it is just some proof of concept that need to be ported, if possible, to a viable product stage or maybe it is just a fake, we will see.
Famous for faking everything is western propaganda
Its not even like "China" invented a new battery tech. It's some battery plant in China which is the place where most batteries are created that's innovated on a design.
There are battery plants in Atlanta, Georgia and Heide, Germany who are pursuing similar advancements. They just don't have the money or the manpower equal to their Chinese peers.
