Metal−organic frameworks are widely used as anode materials for lithium-ion batteries (LIBs) because of their high specific surface areas and rich surface-active sites. However, their poor electronic conductivity and weak structural durability lead to rapid capacity fading during cycling. To solve these problems, NiRu-MOF nanotubes were templated to synthesize Ru-doped biphasic selenide nanotubes wrapped with a nitrogen-doped carbon layer (Ru−Ni 3 Se 4 /NiSe@NC). X-ray photoelectron spectroscopy and EDS tests confirm that Ru element has been successfully introduced into nanotubes. Density functional theory calculations further discover the decreased band gap and increased conductivity of Ru−Ni 3 Se 4 /NiSe@NC owing to the Ru doping effect. As the anode material for LIBs, the Ru−Ni 3 Se 4 /NiSe@NC delivers a large specific capacity of 1138 mA h g −1 at 100 mA g −1 and an excellent reversible capability of 452 mA h g −1 at 10,000 mA g −1 after 3000 cycles. The Ru−Ni 3 Se 4 /NiSe@NC//LiCoO 2 full cell also presents a specific capacity of 434 mA h g −1 at 200 mA g −1 after 200 cycles. This work extends the NiRu-MOF family of materials to develop promising anode materials for high-performance LIBs.

The significance of exploring optimal electrode materials cannot be overstated, particularly in mitigating the critical issues posed by sluggish redox kinetics, significant volume variations, and severe structural collapse resulting from the insertion and extraction of sodium ions. These efforts are crucial for enhancing the longevity and rapid charging capabilities of sodium‐ion batteries (SIBs). Herein, a defect engineering strategy for the in situ encapsulation of single‐phase ternary iron phosphoselenide into porous carbon by robust chemical bonds with the formation of rod‐like multicavity nanohybrids (FePSe3@C) is presented. The incorporation of Se atom not only modulates the electronic structure of the central metal Fe atom and enhances the intrinsic electrical conductivity, but also generates numerous additional reaction sites and accelerates the reaction kinetics of FePSe3@C, as corroborated by theoretical calculations and kinetic analysis. Notably, the FePSe3@C demonstrates an outstanding rate capability of 321.7 mAh g−1 even at 20 A g−1 and long cycling stability over 1000 cycles. The sodium‐ion full cell, pairing the FePSe3@C anode with the Na3V2(PO4)3@C cathode, exhibits a remarkable energy density of 202 Wh kg−1, demonstrating its practical applicability. This work provides a controllable defect and morphology engineering strategy to construct advanced materials with fast charge transfer for high‐power/energy SIBs.

Transition metal selenides (TMSes) are considered promising candidates for the anodes of sodium‐ion batteries (SIBs) due to their substantial theoretical capacity. However, TMSes still face with inferior cycling lifespan caused by sluggish Na+ diffusion kinetics and vigorous volume variations during dis/charge processes. Engineering heterostructure is an attractive solution for rapid Na+ transfer, and introducing carbonaceous materials also facilitates enhanced conductivity and structural stability. Herein, CoSe/MoSe2 heterostructure combined with homogeneous carbon composites are rational designed. The kinetic analysis and theoretical calculations verified that heterointerface engineering induced build‐in electric field effect can amplifies the Na+ diffusion kinetics, while carbon contributes to enhanced electrical conductivity and structural stability. Expectedly, the CoSe/MoSe2‐C exhibits high capacity and extremely ultra‐long lifespan (320.9 mAh g−1 at 2.0 A g−1 over 10,000 cycles with an average decay of only 0.01781 mAh g−1 per cycle). Furthermore, in situ X‐ray diffraction (XRD), ex situ X‐ray photoelectorn (XPS), and high‐resolution electron microscopy (HRTEM) are exploited to explore the Na+ storage mechanism. In addition, the Na3V2(PO4)3@rGO//CoSe/MoSe2‐C (NVP@rGO//CoSe/MoSe2‐C) pouch‐type full‐cells are successfully assembled and delivered satisfactory performance. This research presents a viable strategy for the targeted engineering of TMSes aimed at enhancing the efficiency of SIBs.
