Carbon Nanowires: Peapod‐like Li3VO4/N‐Doped Carbon Nanowires with Pseudocapacitive Properties as Advanced Materials for High‐Energy Lithium‐Ion Capacitors (Adv. Mater. 27/2017)

In article number 1700142, Xiaojun Wu, Yan Yu, and co-workers report a highenergy lithium-ion capacitor using Li3VO4/N-doped carbon nanowires as the anode and activated carbon as the cathode. The N-doped carbon-encapsulated Li3VO4 nanowires display a low insertion voltage and fast rate kinetics, features that are better than are found for many other Li+ insertion anodes. The combination of the Li3VO4 anode and the activated carbon cathode could lead to promising lithium-ion capacitors that are not attainable by conventional electrochemical energy-storage systems.
