“…Various transition metal sulfides, such as CoS x , Co 9 S 8 /MoS 2 , Bi 2 S 3 and so on, have been investigated as both LIBs and SIBs anode. [32,46] Figure 6b exhibits the discharge/charge profiles of the CuCo 2 S 4 sub-microsphere electrode at 200 mA g À 1 . In this paper, the CuCo 2 S 4 submicrosphere was also evaluated as SIBs anode.…”

“…The irreversible capacity fading in the first cycle is caused by the decomposition of the electrolyte and the formation of SEI layer, which usually occurs in micro/nanostructured conversion-type anodes. [32][33] After the initial capacity loses, the discharge/ charge curves are nearly overlaps in the next cycles, revealing the high reversibility in lithium-ion batteries.…”

“…[45] In the anodic scan, three major oxidation peaks and two weak peaks can be observed, which could be assigned to the desodiation process and the oxidation of metal Cu and Co. [10][11] In the second cycle, the corresponding three reduction peaks can be ascribe to the sodiation process and reversible reduction of Co(III), Co(II) and Cu(II). [32,46] Figure 6b exhibits the discharge/charge profiles of the CuCo 2 S 4 sub-microsphere electrode at 200 mA g À 1 . The sample displays a broaden platform at around 0.8 V during the first discharge scan and three platforms during the first charge cycle, which is consistent with the CV results.…”

Ternary transition metal sulfides have come into notice as a new class of prospective material with multiple applications in energy storage. In this work, CuCo 2 S 4 sub-microspheres with sizes of 0.3-0.5 μm were prepared by a facile one-pot solvothermal method. This method combines chemical coprecipitation and sulfidation processes into one pot to make it low-cost and time-saving by controlling the volume ratio of mixed solvent. The as-prepared CuCo 2 S 4 sub-microsphere exhibits an outstanding energy storage performance as dual anodes for lithium/sodium-ion batteries. It possesses a high specific capacity of 1081.3 mA h g À 1 at 100 mA g À 1 after 100 cycles with pseudocapacitive properties in lithium-ion batteries and 522.4 mA h g À 1 at 200 mA g À 1 after 140 cycles in sodium-ion batteries. The superior electrochemical performances of CuCo 2 S 4 sub-microspheres forecast they will be a kind of competitive anode materials for lithium/sodium-ion batteries.

A novel and facile approach has been utilized to synthesize zinc tin sulfide@reduced graphene oxide (ZnSnS 3 @rGO) through aqueous reaction of Na 2 SnO 3 and Zn(CH 3 COO) 2 , combined with a subsequent solvothermal reaction and an annealing process. The as-prepared ZnSnS 3 @rGO nanocomposite exhibited an excellent sodium-and lithium-ion-storage performance with large specific capacity, high rate capability, and ultralong cycle life. When used in Na-ion cells, the ZnSnS 3 @rGO nanocomposite delivered a capacity of 472.2 mAh g À 1 at 100 mA g À 1 and retained a specific capacity of 401.2 mAh g À 1 after 200 cycles. In Li-ion cells, the ZnSnS 3 @rGO nanocomposite delivered a capacity of 959.2 mAh g À 1 at a current density of 100 mA g À 1 and maintained a specific capacity of 551.3 mAh g À 1 at a high current density of 1 A g À 1 upon 500 cycles. The electrochemical performance results reveal that the integration of uniformly dispersed metal elements and an interconnected carbon matrix could help release the stress of volumetric excursion and provide fast electron/ion transport, leading to a remarkable electrochemical performance.

“…4,5 On the other hand, commercial graphite anode is not suitable for SIBs because its interlayer spacing is smaller than the diameter of Na + . 6,7 Thus, exploring suitable anode materials is urgently required for SIBs. In contrast to transition metal oxides, transition metal suldes are kinetically favorable for conversion reactions, which makes them have more potential with other anode materials.…”
