“…In the case of MnOeC, the main peaks observed in the XPS spectrum were O1s with peak locating at 531.4 eV and Mn2p with two peaks locating at 641.5 eV for Mn2p 3/2 and 653.2 eV for Mn2p 1/2 , which are the characteristics of MnO [49,50]. In the case of MnSeC, the S2p peak at 160.9 eV was observed in the XPS spectrum along with the peaks for Mn2p 3/2 and Mn2p 1/2 , which are consistent with the reference value of MnS [51,52]. The MnS powders prepared from the spray solutions with dextrin contents of 0 and 17 g L À1 have mean crystallite sizes of 19 and 17 nm, respectively, as calculated from the (200) peak widths using Scherrer's equation.…”

Novel MnS nanoclusters were synthesized on nickel foam (NF) using a successive ionic layer adsorption and reaction (SILAR) method. MnS nanoclusters with different sizes were obtained by varying the number of deposition cycles. The crystal structure, chemical composition, and surface microstructure of the electrodes were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field emission scanning electron microscopy, and high resolution transmission electron microscopy. The electrochemical behavior of the MnS nanoclusters was examined by cyclic voltammetry, galvanostatic charge-discharge, cycling test, and electrochemical impedance spectroscopy. The MnS nanoclusters prepared with 90 SILAR cycles showed the best supercapacitance in a 6 M KOH aqueous electrolyte with a specific capacitance of 828 F g À1 at a scan rate of 5 mV s À1 and cycling stability of 85.2% after 5000 charge-discharge cycles.Moreover, an asymmetric supercapacitor (ASC) was assembled with the as-prepared MnS electrode on NF as the positive electrode, hydrothermally prepared reduced graphene oxide (rGO) on NF as the negative electrode, and PVA-KOH gel as the electrolyte. The MnS@NF//rGO@NF ASC showed excellent electrochemical performance with maximum energy and power densities of 34.1 W h kg À1 and 12.8 kW kg À1, respectively. The ASC also showed a capacitive retention of 86.5% after 2000 charge-discharge cycles, highlighting its practical application for energy storage.

“…These deficiencies result in rapid capacity fading and poor cycling performance. Among the TMSs, MnS is a promising material with potential applications in photoluminescence, microwave absorption, supercapacitors, and LIBs . When used as an active material for LIB anodes, the MnS crystal can react with lithium through the following electrochemical reaction: MnS+2 Li + +2 e − ↔Mn+Li 2 S. The resulting theoretical capacity of MnS (616 mA h g −1 ) is higher than that of the currently used graphite‐based anode, and thus, has attracted tremendous attention.…”

With the aim of enhanced cyclic stability and rate capability for lithium storage of MnS‐based anode materials, a composite consisting of mesoporous MnS nanoparticles and nitrogen and sulfur co‐doped graphene (NS‐G/MnS) can be synthesized by a facile one‐pot solvothermal procedure with thiourea as the single nitrogen and sulfur precursor. The resultant composite serves as an active anode material for lithium‐ion batteries (LIBs) and exhibits a large specific capacity, good rate capability, and excellent cyclic stability. The superior lithium storage property can be ascribed to the synergistic effect between the NS‐G nanosheets and mesoporous MnS nanoparticles. The NS‐G/MnS composite with superior lithium storage properties can be considered as a promising candidate for high‐performance LIB anodes.
