Better article with a youtube vid... http://www.extremetech.com/extreme/182500-dual-carbon-batter... . I'm particularly happy if this leads to less mining of Lithium.

From the picture [1] it looks like they still use Lithium inside the battery (Li+)

Yeah in the video they mention Li+ ions. So I guess it's still a lithium battery but a different variation. https://www.youtube.com/watch?v=OJwZ9uEpJOo&feature=youtu.be...

The guy goes on to say eventually they'll make them just out of carbon but God knows how the physics will work then. You need some sort of chemical reaction to produce the electrical power along the lines of http://en.wikipedia.org/wiki/Lithium-ion_battery#Electrochem...

The carbon only bit sounds like management / marketing bs

What about the 'A-' ? I think they invented some new element ! ;)

Apparently A- means anion and is a generic term for assorted anions. Shame it's not a new element. That would be cool.
