Stark Battery Tech Thread

Maybe he is right, maybe he is wrong... It's very brave of him to say that is a lithium battery and that if it turns out not to be lithium, he will donate $5,000 to a charity of Donut Labs' choice.

This vid is really great and knowledgeable.

Independent testing is a must but as he says, probably the most important and easiest test to prove it is indeed a solid state battery would have been to simply ask VTT to cut the cell in half so... why didn't they? I mean, they claim it's cheaper to produce.

So basically they're selling a 400 Wh/kg without Li that has all the hallmarks of a 300 Wh/kg Li battery. Best case scenario looks like it's a top NMC battery, with slightly better energy density than Molicel P60B (7%) and maybe able to charge twice as fast.

He's pointing out, as I did, that we'll need proof that all independent tests will be carried on the same cells (at least same cells chemistry), this is quite important.

can you charge it off a 110 volt wall socket

 

[markhamr]

can i get the portable charger with that

It might be part of the scam, but it is a lot of trouble to scam this far and to take a product this far --though it has been done before. If it is a scam Lehtimaki is going to have lose weight if he wants to compete with the top rock stars in the snake oil field:

I don't really care if it's Li, SSB or rainbows that fill those battery's. I only care for the output of whatever is in the ''black box''.

If it performs to spec i'm happy.

Seems that the limit cutoff of 90c degrees on the test was part of VTT safety protocol, not that the cell can't handle it... along with a lot of interesting information on this video

I found the above video more objective than Ziroth's video. But this 2nd video arrives at the same conclusion about the voltage curve, NMC lithium ion...

If quacks like a duck...
