A Donald L. Boss and Garfield Heights was first introduced activated carbon for electrolytic capacitor by a standard oil company (Ohio) on 27 Oct. 1970, which has a disc-shaped capacitor, and in 1970 it received a U.S. patent and was licensed by the Nippon Electric Company (NEC).
Carbon-based capacitor-type electrodes 4.1.1 Carbonaceous materials. AC was a dominating cathode material in the early research of LICs based on the energy-storage mechanism of surface adsorption, since it exhibits high surface area (∼3000 m2 g−1), excellent conductivity (∼60 S m−1) and good chemical stability.
Apart from battery-type electrodes, carbon-based materials also play an important role in the design of capacitor-type electrodes of LICs, which focus on carbonaceous materials as cathodes. The prospects and challenges in this field are also discussed. Zhiqiang Niu is a Professor at the College of Chemistry, Nankai University.
