Thread for new battery breakthrough PR releases

Hadn't seen this European pouch cell mentioned here. 402Wh/kg, 8.9C pulsed power, Lithium-metal chemistry, and apparently in production.

BASQUEVOLT Launches BQV400L, a new benchmark for European battery cells

With 402 Wh/kg energy density and European manufacturing, the BQV400L sets a new standard for what a commercially available battery cell can deliver in Europe. The launch marks BASQUEVOLT’s transition from deep-tech development to industrial deployment, and a new phase of ambition for European...

Honestly, their presentation strikes me as being just like Donutlab. Regardless of whether they have that cell or not, failing to list key specifications such as weight and dimensions is a sign of blatant unprofessionalism, particularly when it comes to pouch format.

This mentions NMC/li-metal chemistry: BASQUEVOLT Launches BQV400L, a new benchmark for European battery cells

Correct, but lithium metal just means nothing except the lithium ions move to something directly on the foil without any alloying or intercalation and gets deposited as lithium metal.

I might be looking too deep into this though, but I'd be really surprised if they're using a lithium foil since it's just so annoying to deal with in manufacturing.

All I was doing was pointing to a page that had the only available answer to your question…insufficient as it is.

Got told by one of my suppliers that EVE is no longer producing the 58E. Seems odd, cause as far as I know that was there highest capacity cell currently available. Anyone know what the roadmap for EVE cells looks like and why they don't have a 6000+mAh cell out yet?

Is Linkdata 65P still the watt hours per kg champion in 21700 land?

No, that would be the Amprius SA112 at low rates.

Found your image.
Yeah, the linkdata looks much better capacity wise if you plan to push it.

At 1A the BAK 65E delivers a tiny bit more energy than the Amprius SA112 which delivers a tiny bit more energy than the Linkdata 65P. You’d never notice the difference between any of them In use.

At 5A and 10A the BAK 65E and Linkdata 65P are tied and deliver noticeably more energy than the Amprius SA112.

Thanks so much everyone.
I think Linkdatas are the ticket since a 2P pack will easily feed 20A-40A to an ebike motor..
Amazing that we can get a 48v ~12ah pack out of just under 4lbs worth of cells... 15 years ago, that sort of battery looked like this & easily 10lbs

EVE 26105 cells can now be ordered in bulk.
