Carbon nanotubes improve capacitor performance
Researchers at MIT have developed a process where capacitor electrodes can be coated with carbon nanotubes, which increases the surface area to store more energy. These new capacitors are capable of storing the same amount of energy as today’s batteries, meaning they can be used to make devices smaller, lighter and more efficient. Additionally, devices with these capacitors would recharge in seconds rather than hours. Engadget reports that prototypes are expected within the next few months with actual product hitting the market in less than five years.
