Herein, a double-confined strategy involving nanosizing and heterointerfaces is proposed to construct nickel-based sulfide composite (PMO@NiS₂/Ni_0.96S@C) with abundant oxygen vacancies (O_V), sulfur vacancies (S_V), and heterostructures. The composite was prepared using liquid-phase in situ self-assembly and low-temperature in situ induction techniques. The double-confined structure and the introduction of vacancies can effectively expose the pseudocapacitive active sites and improve the operating voltage window range of nickel nanosulfides to enhance pseudocapacitive performance. It is determined that anions and cations in the electrolyte are collectively implicated in the energy storage process. Meanwhile, electrochemical quasi-in situ XPS, in situ electrochemical quartz crystal microbalance (EQCM), and theoretical calculations based on density functional theory (DFT) were utilized to verify the energy storage mechanisms of anions and cations in the electrolyte. Furthermore, a pseudocapacitive reaction mechanism for the composites is proposed, which encompasses a novel charge storage coupling effect between the surface redox reaction of the electrolyte anions and the intercalation/de-intercalation of the electrolyte cations at the interlayer and heterointerface.
