Flex­ible and trans­parent super­ca­pac­itor based on nanomaterials

Devel­oped in Jung’s lab two years ago, the nanocup used for these super­ca­pac­itors consist of nanoscopic divots etched into an alu­minium film and then layered with carbon atoms using stan­dard carbon nan­otubes.

The new supercapacitor’s nov­elty derives from the large sur­face area and the open tex­tured sur­face of the nanocups. This mor­phology allows them to come into greater con­tact with the elec­trolyte, which drives the for­ma­tion of an elec­trical field and thus the energy storage functionality.

The super­ca­pac­itor, which has not yet been opti­mized, is able to store energy and pro­vide power at levels com­pa­rable to other devices. The dif­fer­ence, how­ever, is its ability to be incor­po­rated into thin film devices. "If we give up trans­parency and mechan­ical flex­i­bility," Jung said, "we can easily go to that level of com­mer­cially avail­able devices. But my goal is not to lose these two qual­i­ties and simul­ta­ne­ously develop high-​​performance energy devices."

The research team has already used a flex­ible and trans­parent pro­to­type to power a light. The group plans to make con­tinued improve­ments in power gen­er­a­tion and energy storage.
