Good Cycling Stability

To date, the fabrication of advanced anode materials that can accommodate both Na+ and K+ storage is still very challenging. Herein, we developed a facile solvothermal and subsequent annealing process to synthesize SnS2/RGO composite, in which SnS2 nanosheets are bonded on RGO, and investigated their potential as anodes for Na+ and K+ storage. When used as an anode in SIBs, the as-prepared SnS2/RGO displays preeminent performance (581 mAh g−1 at 0.5 A g−1 after 80 cycles), which is a significant improvement compared with pure SnS2. More encouragingly, SnS2/RGO also exhibits good cycling stability (130 mAh g−1 at 0.3 A g−1 after 300 cycles) and excellent rate capability (520.8 mAh g−1 at 0.05 A g−1 and 281.4 mAh g−1 at 0.5 A g−1) when used as anode for PIBs. The well-engineered structure not only guarantees the fast electrode reaction kinetics, but also ensures superior pseudocapacitance contribution during repeated cycles, which has been proved by kinetic analysis.

The paper reports a kind of NiCo2O4 material with urchin-like morphology. This material was prepared using a facile strategy of hydrothermal process followed by calcinations, and exhibits an excellent electrochemical performance. For example, it delivers a specific capacitance high up to 1167[Formula: see text]Fg[Formula: see text] at 1[Formula: see text]Ag[Formula: see text] and still retains a value of 1095[Formula: see text]Fg[Formula: see text] at 10[Formula: see text]Ag[Formula: see text], showing a good rate capability; after suffering from 3000 cycles at 10[Formula: see text]A[Formula: see text]g[Formula: see text], the specific capacitance has only a decay of 12%, presenting a good cycling stability.
