“…Moreover, due to their multiple redox reactions, layered double hydroxides (LDHs) show a large specific surface area [20][21][22]. However, their performance is still hampered by their low structural stability and poor dielectric properties [23,24]. The combination of Ni 3 S 2 and NiMo-LDH structures might provide abundant electrochemical active sites and protect the active material from clumping or collapsing during charging and discharging.…”

Ni3S2 is a kind of transition metal sulfide (TMD) with excellent electrical conductivity and electrochemical activity. To further enhance the specific capacity of Ni3S2-based supercapacitors, we synthesize several nanosheet-decorated Ni3S2@NiMo-LDH nanostructures by a combination of hydrothermal and electrodeposition processes. The mesoporous structure provides a large number of electroactive sites, which shortens the charge transfer distance and increases the specific surface area of electrode materials. The assembled asymmetric supercapacitor shows an energy density of 62.8 W h kg−1 at 2701.6 W kg−1 and long-term cycling stability.
