Alina is a Ph.D. candidate and student researcher at UC Berkeley. When she is not researching energy storage materials for supercapacitor electrodes, she is often outside hiking in the various Bay Area wildernesses, exploring and photographing the many beauties of the west coast, and trying very hard not to be the worst skiier this side of the Rockies.
Carbon Nanotube Films for Energy Storage Applications [BPN606]
As energy demands continue to rise, it becomes imperative to have efficient energy storage
devices with high energy and power density. At the same time, the space inside devices continues
to shrink, making energy storage devices which possess not only high energy/power density, but
also an adjustable shape to fit into various form factors an ideal solution. Energy storage
devices made from flexible electrodes could be attractive in a roll-up or surface-conformed format
to minimize space usage. A mechanically flexible CNT supercapacitor electrode is demonstrated
using a water solution-assisted film lift-off and densification process. The electrode exhibits
the following three features: (1) each CNT has a natural contact to its as-fabricated current-
collecting metal layer; (2) the CNTs and the bottom metal layer are intact during the water-assisted
lift-off process; and (3) the in- situ liquid evaporation and densification process naturally
occurs to dramatically increase volumetric energy density. Because of the ability of the film to
be lifted off of its original growth substrate, the application for same-chip CMOS energy storage
devices is feasible. In addition, this flexible CNT supercapacitor electrode has the potential to
conform to various surfaces, as well as to be implemented in devices which are required to bend
with use, such as in roll-up electronics.
