The fast capacity decay of existing anode materials at a high rate is a thorny problem that hinders the thriving development of sodium ion batteries (SIBs). Herein, we present a unique anode material constructed via cuprous sulfide hollow nanospheres (CuS HNs), which can achieve ultrafast sodiation-desodiation at high rate (20 A g–1) and stable cycling 2000 times without obvious capacity degradation (250.1 mAh g–1, capacity retention of 93%). As far as we know, this excellent rate performance is superior to most of the other currently known metal oxides/sulfides anode materials for SIBs. It is believed that the contribution for high-rate sodium storage of CuS HNs mainly comes from the synergistic effect between hollow nanosphere structure and surface pseudocapacitive behavior. The open hollow nanostructure allows the pseudocapacitive storage simultaneously on the inner and outer surfaces of the nanospheres. Meanwhile, the pseudocapacitive behavior can relieve the large stress of nanospheres at high rate and retain the structural stability of electrode materials. The feature of ultralfast charging and discharging of CuS HNs without obvious capacity sacrifice would be expected to provide a strong boost for the large-scale application of SIBs.

“…Other transition metal sulfides, such as manganese sulfide [102,103], titanium sulfide [104,105], bismuth sulfide [106][107][108] and multicomponent metal sulfides, are also potential anode materials, but they have not been widely reported.…”

“…Furthermore, the stable C-S-Mn bond makes an important contribution to the highly reversible reaction of the material. Therefore, the MnS@NSC composite achieves excellent cycling stability (329.1 mA h g −1 after at 1 A g −1 3000 cycles) [102]. Liu et al prepared α-MnS@N, S-NTC composites by the in situ encapsulation of α-MnS nanoparticles (NPs) in carbon nanotubes with N and S atoms for sodium-ion battery anode materials.…”

The metal chalcogenides (MCs) for sodium-ion batteries (SIBs) have gained increasing attention owing to their low cost and high theoretical capacity. However, the poor electrochemical stability and slow kinetic behaviors hinder its practical application as anodes for SIBs. Hence, various strategies have been used to solve the above problems, such as dimensions reduction, composition formation, doping functionalization, morphology control, coating encapsulation, electrolyte modification, etc. In this work, the recent progress of MCs as electrodes for SIBs has been comprehensively reviewed. Moreover, the summarization of metal chalcogenides contains the synthesis methods, modification strategies and corresponding basic reaction mechanisms of MCs with layered and non-layered structures. Finally, the challenges, potential solutions and future prospects of metal chalcogenides as SIBs anode materials are also proposed.

In this paper, we present a novel and low - cost method for preparing copper sulfide films on polyamide. Non-treated as well as pre-treated PA6 films by 3 different methods (in boiled water; in NaOH solution; in boiled water and then in NaOH solution) were used for the formation of Cu2S layers by the sorption-diffusion method. Molten sulfur has been used as a sulfurization agent. The XRD, FTIR, and UV-VIS methods were used to characterize the structural, optical, and electrical properties of samples and to track changes in samples after each treatment stage. The sheet resistance of Cu2S layers depends on the pre-treatment method and varied from 7 k?/sq to 6 M?/sq. The optical band gaps (Eg) for direct and indirect transitions are determined to be 2.61-2.67 eV and 1.40-1.44 eV, respectively. Furthermore, the optical constants n, k, and ? are determined from UV-VIS measurements.
