Mixed metal sulfides (MMSs) have attracted increased attention as promising electrode materials for electrochemical energy storage and conversion systems including lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), hybrid supercapacitors (HSCs), metal–air batteries (MABs), and water splitting. Compared with monometal sulfides, MMSs exhibit greatly enhanced electrochemical performance, which is largely originated from their higher electronic conductivity and richer redox reactions. In this review, recent progresses in the rational design and synthesis of diverse MMS‐based micro/nanostructures with controlled morphologies, sizes, and compositions for LIBs, SIBs, HSCs, MABs, and water splitting are summarized. In particular, nanostructuring, synthesis of nanocomposites with carbonaceous materials and fabrication of 3D MMS‐based electrodes are demonstrated to be three effective approaches for improving the electrochemical performance of MMS‐based electrode materials. Furthermore, some potential challenges as well as prospects are discussed to further advance the development of MMS‐based electrode materials for next‐generation electrochemical energy storage and conversion systems.

“…In particular, NiS has garnered a strong research interest because of its various phases, including NiS, NiS 2 , Ni 3 S 2 , Ni 3 S 4 , Ni 7 S 6 , and Ni 9 S 8 , high theoretical capacity (NiS (1062 F g −1 ) and Ni 3 S 2 (1204 F g −1 )), and the corresponding potential applications in a diverse number of fields such as those of supercapacitors, batteries, and electrocatalysis, among others . Even though the metal sulfides possess electrochemical properties that are superior to those of their counter‐oxide forms, the ongoing concerns are regarding the conductivity, aggregation of neighboring particles (during synthesis and long‐term cycling), and cycling stability, as these are the key factors in the determination of the electrochemical performance . In the previously mentioned application areas, a unique morphology that can improve the conductivity and withstand the stresses during cycling is indispensable for the imparting of a high electrochemical activity.…”

Nickel sulfides have drawn much attention with the benefits of a high redox activity, high electrical conductivity, low cost, and fabrication ease; however, these metal sulfides are susceptible to mechanical degradation regarding their cycling performance. Conversely, hollow carbon shells exhibit a substantial electrochemical steadiness in energy storage applications. Here, the design and development of a novel millerite core-nitrogen-doped carbon hollow shell (NiS-NC HS) structure for electrochemical energy storage is presented. The nitrogen-doped carbon hollow shell (NC HS) protects against the degradation and the millerite-core aggregation, giving rise to an excellent rate capability and stability during the electrochemical charging-discharging processes, in addition to improving the NiS-NC HS conductivity. The NiS-NC HS/18h supercapacitor electrode displays an outstanding specific capacitance of 1170.72 F g (at 0.5 A g ) and maintains 90.71% (at 6 A g ) of its initial capacitance after 4000 charge-discharge cycles, owing to the unique core-shell structure. An asymmetric-supercapacitor device using NiS-NC HS and activated-carbon electrodes exhibits a high power and energy density with a remarkable cycling stability, maintaining 89.2% of its initial capacitance after 5000 cycles.
