Developing sodium ion battery (SIB) anode materials of a low-cost and high-capacity nature for future large-scale applications still involves challenges.
Hierarchically core–branched iron cobalt selenide arrays coated with N-doped carbon shell were designed and synthesized on carbon cloth, showing prominent electrochemical performance both in half-cell and full cell sodium ion batteries.
