Bifunctional artificial sodium polysulfide mediators boosting the sodium storage performance of the Fe<sub>3</sub>O<sub>4</sub> anode
Artificially incorporating sodium polysulfides into Fe<sub>3</sub>O<sub>4</sub>@rGO anodes enables <i>in situ</i> formation of uniformly dispersed Cu<sub>2</sub>S nanocrystals, acting as reversible redox-active sites to enhance capacity and as kinetically favourable interparticle bridges to accelerate Na<sup>+</sup> diffusion. This work demonstrates a simple strategy for interparticle engineering in sodium-ion batteries using multifunctional polysulfide mediators.
