| Abstract Scope |
Energy storage in aerospace applications is challenging due to the cost of maintenance and repairs as well as the harsh conditions that the devices must survive. Batteries are one common method of storing energy on satellites and other aerospace equipment; however, replacing these batteries when they fail is often cost prohibitive. Room temperature ionic liquid-based supercapacitors have demonstrated power densities of 400 kW/kg and energy densities of 800 J/kg making them a viable energy storage alternative. Thermal cycling in an environmental chamber will be used to test potential supercapacitor designs prior to in-orbit testing. Supercapacitors will be fabricated using a photolithography process and chemical vapor deposition system to create vertically-aligned carbon nanotube electrodes. The environmental chamber will be used to recreate, as closely as possible, the temperature of a low earth orbit for comparing the performance of supercapacitors with different ionic liquid electrolytes using cyclic voltammetry. |
