High‐power anode materials are essential for development of high‐performance sodium‐ion battery–supercapacitor hybrid systems (sodium‐ion hybrid supercapacitors, Na‐HSCs). On page 3711, J. Lee and co‐workers report the synthesis of Nb 2 O 5 @carbon core–shell nanoparticles and reduced graphene oxide nanocomposites (Nb 2 O 5 @C/rGO), and their application to Na‐HSCs as anode materials. The Na‐HSCs using Nb 2 O 5 @C/rGO anode materials deliver high energy and power densities with stable cycle life.
