Sweet. Maybe they will be able to bring it to market in 10 years.

Note to Pure Lithium - Don’t hire any grad students who have just come over from China.

then bursts magnificently into a ball of flame

[crusty old prospector]

There are lots of lithium-laden brines in northeastern Texas and southern Arkansas in the Smackover Formation. It is likely that it will extend into Mississippi and Alabama. Exxon and Chevron are now working it.

Will it burn down your garage as readily as the current ones?

[Georgia Girl 2]

Excellent!

China steals this new technology in 3,2,1....

Thanks to the vanadium cathode’s ability to operate at temperatures up to 700°C, the battery is significantly more fire-resistant.

I read the whole promising article. I didn’t see a weight listed. How big is it please?

[Fresh Wind]

There’s antimony, arsenic, aluminum, selenium
And hydrogen and oxygen and nitrogen and rhenium
And nickel, neodymium, neptunium, germanium
And iron, americium, ruthenium, uranium...

Wow. Ty.

"I read the whole promising article. I didn’t see a weight listed. How big is it please?"

Their website claims to have 2X the capacity at half the weight of a comparable conventional Lithium-Ion battery for 30% cheaper materials.

YMMV, but if they can even get close to these claims, then they've got something, given the other claims for charge cycles and heat resistance.

Ha! You gave me a great laugh with that line!
I agree.

[smokingfrog]

They already make batteries that will last for more cycles, but if they can reduce the weight & cost, that would be significant. Another issue is how are all these batteries going to be recycled?

[NorthMountain]

Hah! It’s easy to discriminate between the smart people who read the article and the smacktards who don’t ...

Thanks for the link. The technology page is quite interesting. 400Wh/kg energy density — by comparison my BattleBorn LiFePO4 100A-h battery (roughly 1200 Wh) weighs ~10kg — so the BattleBorn is about 1/3 the energy density that PureLithium claims.

But the most important reason to be excited about PureLithium is that the CEO is smokin’ hot. Unlike their batteries, of course I hope. :-)

I enjoy it..............🙄
