2D Crumpled Nitrogen-doped Carbon Nanosheets Anode with Capacitive-Dominated Behavior for Ultrafast-Charging and High-Energy-Density Li-ion Capacitors

Li-ion capacitors (LICs) are promising to simultaneously achieve battery-level energy density and supercapacitor-level power density, but the slow kinetics of diffusion-controlled battery anodes lead to unmatched two-electrode kinetics at the...
