Has anyone seen this?
Prius battery guru says future EVs will be powered by nothing but cotton

Considering the Prius's battery technology, I'm not sure it says much. I read it earlier today and I'm putting it on the "to watch" pile next to the other hundreds of statements that have been made over the past 3 years or so. Rough consensus and working code and all that...

It says the CTO also worked on the Model S battery. See the CTO's bio here:

Have there been any statements made to indicate that the new Tesla battery factories will for sure be lithium-ion?

Very interesting but one question. How much more range with these new batteries provide if TM is already getting 300 mile and 265 EPA rated miles from the current battery tech?

I know as much as the website/video says, so no idea! But if the claims are true, this is one interesting technology... batteries using cotton!

Cotton, for a battery?

Are you sure this story isn't fabric ated?

They may be simply stringing us along.

Gigaom's Katie Fehrenbacher has an article on it, too
A Japanese startup unveils a long-lasting and safer battery made from carbon Tech News and Analysis

But it contains several points that would set off my BS alarm if not cross checked against other sources:

"highly flammable lithium oxide" - oxides are product of oxidation AKA fire

"doesn’t contain rare earth materials and metals" - no metals at all? I thought only the electrodes were from carbon. The PJP website shows Li+ dots moving around in the cell.

Ever tried to soak a cotton ball in a highly flammable liquid? Apply spark or fire, and the cotton ball evaporates entirely in a whooompth of a second!
