Summary Ferrous sulfides have high theoretical capacity in the electrochemical storage of Na‐ion and K‐ion, but its obvious volume change during the storage process greatly affects its cycling performance at high current density. In this regard, we construct a unique composites structure of Nitrogen‐doped carbon shell coated FeS nanoparticle with inner void spaces. As an anode in Na‐ion and K‐ion batteries, this structure could provide excellent cycling performance at high rate of charge/discharge process (560 mAh/g at 0.5 A/g for 300 cycles in Na‐ion battery and 322 mAh/g at 1 A/g for 300 cycles in K‐ion battery). Further research finds the inner void space could not only provide buffer space for the volume change of FeS nanoparticles, but also maintain a stable outer carbon shell during the electrochemical process. These behaviors greatly promote the reversibility of FeS at high rate charge transfer process. Consequently, the construction of inner void space in graphitized carbon shell in this work could be considered as an important reference for the promotion of electrochemical storage in other transitional metal compound system.

“…Therefore, both peaks had the same characteristics. The Pb4f7/2 binding energy at 138.86 eV was ascribed to PbCO3 (Cozza et al, 1992;Feng et al, 2016). The fitting results of the Pb4f7/2 peak in the spectrum of the cerussite after thermochemical processing with an F/P mole ratio of 0.1 (Sample B) indicated that the peak consisted of three components.…”

“…investigated the adsorption behaviors of copper ions on the chalcopyrite surfaces and found a new viewpoint about self-activation of the copper ions. e same group also studied the types, structures, and compositions in natural pure chalcopyrite and measured the total concentrations of Cu (C CuT ) and Fe (C FeT ) released from the inclusions [18,19]. Zhang et al investigated the effect of Fe (III) ions on the flotation of spodumene, albite, and quartz minerals using sodium oleate (NaOL) and found Fe (III) as an activator for the flotation [20].…”

e treatment of smelting slag has attracted much attention nowadays. is study investigates the influence of Na 2 S, CuSO 4 , and FeCl 3 on sulphidizing flotation of copper oxide. e results show that a proper Cu 2+ concentration can increase the sulphidizing effect of copper oxide, while Fe 3+ inhibits the sulphidizing effect. Further analysis shows that Cu 2+ ions can reduce the surface potential, increase the S 2− adsorption, then generate more polysulfide, and therefore promote the sulphidizing flotation. However, Fe 3+ ions would increase the surface potential, reduce the S 2− adsorption, generate more sulfur element, and therefore inhibit the sulphidizing flotation.
