제목 | Morphology and doping effects of porous carbon on organic zinc-ion hybrid supercapacitor cathodes |
초록 | Hybrid supercapacitor is in the spotlight as a next-generation energy storage device that uses the existing capacitor and battery electrodes to complement each other's shortcomings. Especially for Zn-ion based hybrid supercapacitor (ZHSC), consisting of battery-type Zn anode and capacitive carbon-based cathode, is one of the most potential candidates for energy storage device. The capacitance of ZHSC depends on the adsorption/desorption of ions in the electric double layer or the redox reaction at the surface of electrode. Therefore, either increasing the surface area of the electrode active material or providing additional functional groups by heteroatom doping could increase the capacitance. In this work, mesoporous carbon microspheres synthesized from the mesocellular siliceous foam template were fabricated and applied to the organic ZHSC system. Due to the mesopores, the surface area for capacitive performance is widened, and high electrode density can be achieved with its spherical and micro-sized shapes. Additionally, nitrogen-doped carbon is expected to improve electrochemical performance by increasing electrical conductivity and wettability with organic electrolytes. |
