Post-lithium-ion batteries (LIBs) have been widely studied owing to the extensive exploitation of lithium resources. Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) are considered suitable alternatives to LIBs; however, the absence of an ideal anode material limits the practical applications of such post-LIBs. The present study demonstrates the application of mesoporous Ni 3 S 2 as an anode material for SIBs and PIBs as well as the advantages of using a porous electrode in a high ionic-conductivity, low-viscosity, ether-based electrolyte. The utilization of mesoporous Ni 3 S 2 as the anode material resulted in extraordinary rate and cycling performances. When SIBs were assembled using mesoporous Ni 3 S 2 as the anode material, capacities of 610 and 154 mAh g −1 were obtained at current densities of 0.2 and 100 A g −1 , respectively. Long-term cycling stability, with an initial capacity of 307 mAh g −1 and a capacity decay of 0.0085% per cycle, was also observed over 5000 cycles at 50 A g −1 . Full cells assembled using Na 3 V 2 (PO 4 ) 3 and Ni 3 S 2 as cathode and anode materials, respectively, delivered exceptional rate and cycling performances. Longterm cycling stability, with a capacity decay of 0.034% per cycle, was obtained over 1500 cycles at 10 A g −1 . When PIBs were assembled using mesoporous Ni 3 S 2 as the anode material, capacities of 534 and 38 mAh g −1 were obtained at 1 and 100 A g −1 , respectively. Long-term cycling stability, with an initial capacity of 411 mAh g −1 and a capacity decay of 0.047% per cycle, was observed over 1000 cycles at 10 A g −1 . Notably, the rate and cycling performances obtained in the present study are superior to those obtained in previous works on the use of Ni 3 S 2 as the anode material for SIBs and PIBs.

“…As displayed in Figure 4d, the rate capability of Ni-Ni 3 S 2 @SC surpasses most other reported Ni 3 S 2 -based materials in SIBs (Table S1, Supporting Information). [44,[50][51][52][53][54][55][56][57][58] Based on previous reports, [59][60][61] a thin and uniform SEI could be formed in an ether-based electrolyte, which is beneficial for achieving superior ICE with high specific capacity. As shown in Figure S6, Supporting Information, the sodium storage performance of Ni-Ni 3 S 2 @SC electrode was also investigated in ether-based electrolytes (1 mol L −1 NaCF 3 SO 3 in diglyme).…”

Transition metal sulfides (TMS) are considered as promising anodes for sodium/potassium ion batteries (SIBs/PIBs), and compositing TMS with conductive nanocarbons is an effective mitigation for improving rate performance and cycling stability. However, such a coupling strategy often decreases the tap density and therefore the volumetric energy of electrode. To achieve fast electron/ion transport and high volumetric capacity simultaneously, herein, a compact nanostructure with hetero Ni‐Ni3S2 nanoparticles embedded in a densified S‐doped carbon matrix (Ni‐Ni3S2@SC) is constructed via a spatially confined “edge‐to‐edge” strategy. Experimental and theoretical results confirm that the carbon matrix and metallic Ni nanoparticles provide fast electron transport pathways at two scales, while the abundant heterojunctions with strong electric fields promote the ion migration and Na/K adsorption. As an anode in SIBs/PIBs, the Ni‐Ni3S2@SC exhibits superior rate capability (289/197 mA h g−1 at 2 A g−1), stable cycling performance (88.1/86.2% capacity retention after 100 cycles), and exceptional volumetric capacity (1048/850 mAh cm−3 at 0.05 A g−1). The impressive energy‐power characteristics for Ni‐Ni3S2@SC anode are further confirmed in full cell batteries and hybrid capacitors. The reported spatially confined “edge‐to‐edge” strategy might be adapted to the construction of various binary and/or ternary metal sulfide dense electrodes for advanced energy storage devices.
