Re: Nanotube Ultracapacitors from MIT



Pluto wrote:

Our analysis shows that the utilization of a matrix of vertically aligned CNTs as electrode structure, can lead to an ultracapacitor characterized by a power density greater than 100kW/kg (three orders of magnitude higher than batteries), a lifetime longer than 300,000 cycles, and an energy density higher than 60Wh/kg.


The latter of which is totally useless.

Gasoline has 9000Wh/kg
