A nanoflower structure of Zn[Formula: see text]Co[Formula: see text]S directly grown on carbon fiber papers (CFP) was successfully designed by a mild two-step hydrothermal method. Benefiting from their fascinating structural features, Zn[Formula: see text]Co[Formula: see text]S/CFP electrode exhibits a maximum specific capacitance of 300[Formula: see text]F[Formula: see text]g[Formula: see text] at current density of 1[Formula: see text]A[Formula: see text]g[Formula: see text] and 84% capacitance retention after 5,000 cycles at current density of 5[Formula: see text]A[Formula: see text]g[Formula: see text]. Subsequently, Zn[Formula: see text]Co[Formula: see text]S/CFP//AC all-solid-state asymmetric supercapacitor (ASC) device is assembled and able to illuminate the red LEDs. ASC devices deliver a maximum energy density of 9.59[Formula: see text]W[Formula: see text]h[Formula: see text]kg[Formula: see text] at a power density of 750[Formula: see text]W[Formula: see text]kg[Formula: see text]. Therefore, this impressive result demonstrates that the nanoflower Zn[Formula: see text]Co[Formula: see text]S have promising applications in the development of high-performance supercapacitors.

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.
