It seems Fisker is intent on building a new EV based on graphene supercapacitors instead of batteries. They have released the first teaser image of the new car:
Since the most interesting piece of this announcement is the claimed breakthrough in graphene supercapacitors, perhaps we can discuss that in this thread, as well.
Here is an article on this claimed new breakthrough storage technology. From the article:
Since the most interesting piece of this announcement is the claimed breakthrough in graphene supercapacitors, perhaps we can discuss that in this thread, as well.
Here is an article on this claimed new breakthrough storage technology. From the article:
Business Insider said:"Graphene shows a higher electron mobility, meaning that electrons can move faster through it. This will, e.g. charge a battery much faster," Lucia Gauchia, an assistant professor of mechanical engineering and energy storage systems at Michigan Technological University, told Business Insider. "Graphene is also lighter and it can present a higher active surface, so that more charge can be stored."
The key technologist behind this claimed breakthrough is Jack Kavanaugh:Business Insider said:"The reason we are not using it yet, even though the material is not a new one, is that there is no mass production for it yet that can show reasonable cost and scalability," Gauchia explained.
But Fisker told Business Insider that his battery division, Fisker Nanotech, was patenting a machine that he said could produce as much as 1,000 kilograms of graphene at a cost of just 10 cents a kilogram.
Business Insider said:Kavanaugh hails from Nanotech Energy, a research group composed of UCLA researchers who specialize in the graphene supercapacitor Fisker plans to use in his car.
Business Insider said:"The challenge with using graphene in a supercapacitor in the past has been that you don't have the same density and ability to store as much energy," Kavanaugh said. "Well we have solved that issue with technology we are working on."
