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.
Nils Kristian Brekke says
3000 charge cycles sound like it will die fairly quickly. It's still a few years for a car, but I could see it break in grid applications rather rapidly.
Chris Norman says
It's made from cotton, though. I would like to know what condition the cotton is in when it's done.
Nils Kristian Brekke says
I don't disagree at all. It just seems it has to get a few improvements before it's viable in things that go through a lot of charge cycles. The "20x" faster argument only really holds if it doesn't need to be charged all the time as well. If the capacity is too low it will just die in 3 years or less.
Chris Norman says
True; but I'm not sure we can measure the costs of such a batter against Lithium batteries today.
Such a battery as this (being 100% recyclable), could be many times less expensive, and it'd shift the costs from cooling systems / exotic raw materials to regularly scheduled maintenance.
If there's no short circuit for discharge, that might even be something the consumer could do.
Paul Spoerry says
They state that the discharge is safe and one of the advantages +Chris Norman. Also… it starts as cotton but only in that they turn the cotton into carbon that they use for the battery.
Chris Norman says
Yes, I understood that about the safety and discharge – but good to know about how they use the cotton. It's a highly renewable raw material.
Thomas Wrobel says
Cool.
