Binary transition metal selenides (BTMSs) are more promising than single (TMS) as anode materials of sodium-ion batteries (SIBs). However, it is still very challenging to prepare high-performance BTMSs in the pure phase, instead a mixture two TMSs. In this study, binary center-based MOF derived selenization strategy was developed iron–cobalt selenide (Fe2CoSe4@NC) and iron–nickel (Fe2NiSe4@NC) nanocomposites phase when wrapped with carbon layers. As material SIBs, Fe2CoSe4@NC exhibits higher long-term cycling performance Fe2NiSe4@NC, maintaining capacity 352 mAh g−1 after 2100 cycles at 1.0 A g−1, which ascribed percentage nanopores, larger lattice spacing, faster Na+ diffusion rate electrode former rather latter.

Abstract Sodium‐ion batteries (NIBs) are gaining momentum, thanks to the increasing demand for energy storage devices and abundant reserves low sodium cost. Transition metals well‐established materials due their high conductivity electrochemical activity. In this work, metal selenides (MSe x ) (M: Ni, Co, Fe) obtained by facile selenization in a single step of transition gallic acid based organic frameworks (MOFs) under Ar flow at 600 °C. As powders undergo selenization, resulting MSe particles encapsulated within amorphous carbon network formed decomposition gallate ligand. The microstructures examined HR‐TEM analyses characteristic interplanar spacing each selenide is measured found coincide with XRD pattern. Meanwhile, specific surface areas were as 121, 152, 155 m 2 /g CoSe , NiSe FeSe, respectively. NiSe/C, /C FeSe/C nanomaterials tested NIB negative electrodes shown have capacity 315, 312, 363 mAh/g, respectively, after 100 cycles current density mA/g while Na‐ion diffusion coefficients (D Na+ calculated range 10 −10 –10 −7 cm /s galvanostatic intermittent titration (GITT) technique.
