Improvement to supercapitors is necessary to match new technologies
Supercapacitors are a type of electrochemical energy storage system that are often used when rapid charge/discharge cycles (burst power) are desired in comparison to) long-term energy storage. As modern technology grows increasingly complex, energy requirements have grown, and continuous research is being conducted to improve supercapacitors.
New innovation improves efficiencies within supercapacitors
Researchers at the Georgia Institute of Technology have developed a new electrode material comprised of vertically aligned multiwalled-carbon nanotubes (VAMWCNTs) with a thin coating of alumina and titania. The result is of using this novel material is a supercapacitor that can store more energy per unit of voltage, has more efficient charging and discharging, and can maintain performance and reliability over multiple cycles when compared to competitors.
The invention is a new composite electrode material designed for use in supercapacitors. The innovation is composed of a hybrid composite material with a thin coating of alumina and titania. Using this composition of materials allows energy storage systems to have increased energy density, power density, and cycle life.
