Nanotechnology offers new approach to increasing storage ability of dielectric capacitors
For Back to the Future fans, this week marked a milestone that took three decades to reach.
Oct. 21, 2015, was the day that Doc Brown and Marty McFly landed in the future in their DeLorean, with time travel made possible by a “flux capacitor.”
While the flux capacitor still conjures sci-fi images, capacitors are now key components of portable electronics, computing systems, and electric vehicles.
In contrast to batteries, which offer high storage capacity but slow delivery of energy, capacitors provide fast delivery but poor storage capacity.
A great deal of effort has been devoted to improving this feature — known as energy density — of dielectric capacitors, which comprise an insulating material sandwiched between two conducting metal plates.
Now, a group of researchers at the University of Delaware and the Chinese Academy of Sciences has successfully used nanotechnology to achieve this goal.
The work is reported in a paper, “Dielectric Capacitors with Three-Dimensional Nanoscale Interdigital Electrodes for Energy Storage,” published in Science Advances, the first open-access, online-only journal of AAAS.
“With our approach, we achieved an energy density of about two watts per kilogram, which is significantly higher than that of other dielectric capacitor structures reported in the literature,” says Bingqing Wei, professor of mechanical engineering at UD.
“To our knowledge, this is the first time that 3D nanoscale interdigital electrodes have been realized in practice,” he adds. “With their high surface area relative to their size, carbon nanotubes embedded in uniquely designed and structured 3D architectures have enabled us to address the low ability of dielectric capacitors to store energy.”
