| Abstract Scope |
To satisfy spikes in power demand, capacitors are used due to their ability to rapidly supply power. However, capacitors deliver orders of magnitude less energy than batteries, and are therefore unsuitable as a primary method of energy storage. Supercapacitors are an energy storage mechanism that blend the energy storage of a battery with the power storage of a capacitor. To enhance energy storage, supercapacitors utilize pseudocapacitance to store energy via faradaic reactions. While carbon nanotubes are capable of participating in faradaic reactions, coating them with a transition metal oxide (TMO) nanofilm greatly increases the pseudocapacitive energy storage. By selecting two different TMOs that have a large potential difference, the operating voltage of the supercapacitor is greatly increased. This potential difference can be utilized by the stability of room temperature ionic liquids to fabricate a supercapacitor with high energy density. |
