In article number 1700142 , Xiaojun Wu, Yan Yu, and co‐workers report a highenergy lithium‐ion capacitor using Li 3 VO 4 /N‐doped carbon nanowires as the anode and activated carbon as the cathode. The N‐doped carbon‐encapsulated Li 3 VO 4 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 Li 3 VO 4 anode and the activated carbon cathode could lead to promising lithium‐ion capacitors that are not attainable by conventional electrochemical energy‐storage systems.
