Summary: In this work, a double design host and guest strategy is proposed to enhance the electrochemical properties of sulfur electrodes in sodium ion storage. The V2O3 adsorbent immobilizes sulfur species, while the selenium dopant improves the electronic conductivity and redox conversion of sulfur cathodes. The synergistic effect between the V2O3 adsorbent and selenium dopant inhibits the shuttle effect and improves the redox kinetics, resulting in greatly enhanced Na-ion storage properties of sulfur cathodes. The as-designed sulfur cathode exhibits excellent rate capability of 663 mA h g(-1) at 2.0 A g(-1) and exceptional cyclability of 405 mA h g(-1) over 700 cycles at 1.0 A g(-1).
