Encapsulating V₂O₃ Nanoparticles in Carbon Nanofibers with Internal Void Spaces for a Self-Supported Anode Material in Superior Lithium-Ion Capacitors

A lithium-ion capacitor (LIC) consisting of a lithium-ion battery (LIB)-type anode and a supercapacitor (SC)-type cathode gains wide attention on account of the integration with the merits of high-energy LIB and high-power SC. However, LIC usually shows low energy/power density at high charge/discharge rate due to the sluggish charge/discharge kinetics of the LIB-type anode. Herein, to address this issue, we develop a self-supported anode...
