Sluggish kinetics and severe volume expansion critically limit the electrochemical performance of sodium‐ion batteries (SIBs). Herein, a novel material combining CoNiSe 2 nanoparticles with pod‐like N‐doped carbon nanofibers (CoNiSe /PCNFs) is designed fabricated. The bimetallic selenide combines redox characteristics Co Ni, which offers more active sites for Na + adsorption. nanocubes show large surface areas, contribute to faster diffusion kinetics. Unique not only serve as reinforcing frameworks inhibit change but also improve conductivity /PCNFs. /PCNFs electrode achieves high capacity 395.8 mAh g −1 at current density 0.1 A after 100 cycles exhibits excellent cycling stability 1000 1.0 284.3 . structure properties shed new light on developing high‐performance selenides SIB anodes.
