Enhanced Electrochemical Performance of Dual-Ion Batteries with T-Nb₂O₅/Nitrogen-Doped Three-Dimensional Porous Carbon Composites.

ABSTRACT: Niobium pentoxide (T-Nb₂O₅) is a promising anode material for dual-ion batteries due to its high lithium capacity and fast ion storage and release mechanism. However, T-Nb₂O₅ suffers from the disadvantages of poor electrical conductivity and fast cycling capacity decay. Herein, a nitrogen-doped three-dimensional porous carbon (RMF) was prepared for loading niobium pentoxide to construct a composite system with excellent electrochemical performance. The obtained T-Nb₂O₅/RMF composites have a well-developed pore structure and a high specific surface area of 1568.5 m² g^-1, which could effectively increase the contact area between the material and electrolyte, improving the electrode reaction and lithium-io
