Abstract Lithium-ion capacitors are envisaged as promising energy-storage devices to simultaneously achieve a large energy density and high-power output at quick charge discharge rates. However, the mismatched kinetics between capacitive cathodes faradaic anodes still hinder their practical application for purposes. To tackle this problem, electron ion transport of both electrodes should be sub...
