| Abstract Scope |
As clean energy becomes more widespread, robust energy storage solutions are needed. Supercapacitors are a class of promising energy storage devices characterized by high charge and discharge rates. Vertically aligned carbon nanotubes (VACNTs) are well known for their promising electrical properties. However, low power density limits the use of CNT electrodes in supercapacitors. Thin films made from transition metal oxides such as titanium dioxide allow for pseudocapacitive redox reactions to occur on the surface of the electrode that improve the energy and power of the resulting devices. Additionally, the use of an alumina base layer further enhances supercapacitor performance. This novel two-layer thin film deposited via ALD allows for supercapacitor devices to be constructed with superior power and energy density. |
