Dual Carbon Battery, who's main ingredient is cotton, looks to usurp Lithium Ion and eventually power cars
They claim:
* Charges 20x faster than the best lithium ion batteries
* Usable life of 3,000 charge cycles
* Is 100% recycleable
* 300 mile range electric vehicles possible without massive battery packs

Sound to good to be true? The guys developing it are the ones who developed the massive battery pack used in the #TeslaMotors  Model S (also has 300 mile range but requires a giant battery pack to do so) and the Toyota Prius.
