ZnS has great potentials as an anode for lithium storage because of its high theoretical capacity and resource abundance; however, the large volume expansion accompanied with structural collapse and low conductivity of ZnS cause severe capacity fading and inferior rate capability during lithium storage. Herein, 0D-2D ZnS nanodots/Ti3C2Tx MXene hybrids are prepared by anchoring ZnS nanodots on Ti3C2Tx MXene nanosheets through coordination modulation between MXene and MOF precursor (ZIF-8) followed with sulfidation. The MXene substrate coupled with the ZnS nanodots can synergistically accommodate volume variation of ZnS over charge–discharge to realize stable cyclability. As revealed by XPS characterizations and DFT calculations, the strong interfacial interaction between ZnS nanodots and MXene nanosheets can boost fast electron/lithium-ion transfer to achieve excellent electrochemical activity and kinetics for lithium storage. Thereby, the as-prepared ZnS nanodots/MXene hybrid exhibits a high capacity of 726.8 mAh g−1 at 30 mA g−1, superior cyclic stability (462.8 mAh g−1 after 1000 cycles at 0.5 A g−1), and excellent rate performance. The present results provide new insights into the understanding of the lithium storage mechanism of ZnS and the revealing of the effects of interfacial interaction on lithium storage performance enhancement.

“…In addition, the complete battery showed a high initial coulombic efficiency of 87.3%, and the coulombic efficiency rose to above 99% after 6 cycles, indicating its good electrochemical reaction reversibility. The battery performance is better than the reported LiFePO 4 @graphene/ZnS@graphene complete battery [31] that retained a capacity of 117.1 mAh•g −1 after cycling at a current density of 100 mA•g −1 for 50 cycles. Figure 8(d) presents the voltage profiles of the complete battery, which reflects the comprehensive effects of the anode and the cathode on the voltage variation in the charge/discharge processes.…”

“…Until now, as far as we know, the evaluation of ZnS anode in complete lithium ion battery systems has seldom been reported, except from the case of LiFePO 4 @graphene/ ZnS@graphene complete battery [31]. Therefore, we presented a new design of complete lithium ion battery fabricated by combining the ZnS@N-C nanoplates anode with the commercial LiNi 0.6 Co 0.2 Mn 0.2 O 2 cathode, the complete battery exhibited good cycling stability up to 120 cycles, and the electrochemical behaviors are further characterized in detail.…”

Metal sulfides are promising anode materials for lithium ion batteries because of the high specific capacities and better electrochemical kinetics comparing to their oxide counterparts. In this paper, novel monocrystalline wurtzite ZnS@N-doped carbon (ZnS@N–C) nanoplates, whose morphology and phase are different from the common ZnS particles with cubic phase, are successfully synthesized. The ZnS@N–C nanoplates exhibit long cycle life with a high reversible specific capacity of 536.8 mAh · g−1 after 500 cycles at a current density of 500 mA · g−1, which is superior to the pure ZnS nanoplates, illustrating the obvious effect of the N-doped carbon coating for mitigating volume change of the ZnS nanoplates and enhancing the electronic conductivity during charge/discharge processes. Furthermore, it is revealed that the ZnS single crystals with wurtzite phase in the ZnS@N–C nanoplates are transformed to the polycrystalline cubic phase ZnS after charge/discharge processes. In particular, the ZnS@N–C nanoplates are combined with the commercial LiNi0.6Co0.2Mn0.2O2 cathode to fabricate a new type of LiNi0.6Co0.2Mn0.2O2/ZnS@N–C complete battery, which exhibits good cycling durability up to 120 cycles at a charge/discharge rate of 1 C after the prelithiation treatment on the ZnS@N–C anode, highlighting the potential of the ZnS@N–C nanoplates anode material applied in lithium ion battery.

“…As illustrated in Figure 4a, for [Cu(pyttz) 2 ]PMo 12 , an irreversible reduction peaks appear at ca. 0.5 V, attributed to the generation of a solid electrolyte interface (SEI) [23] , which disappear in the following cycles, a common phenomenon in LIBs [24] . In the following cycles, two pair of peaks occur at 0.22 V/0.98 V and 1.13 V/1.55 V, attributed to the intercalation/deintercalation of Li + .…”

To address the poor electronic conductivity and easily dissolved in electrolyte of polyoxometalates (POMs), and considering the high electrical conductivity and configuration advantages of crumpled graphene balls (CGBs), herein, a series of POM‐based coordination polymers [Cu(pyttz)2]PMo12@CGB (n, n=1, 2, 3) were successfully synthesized, and electrochemical lithium storage performance and lithium ion diffusion kinetics were comprehensively investigated. Galvanostatic intermittent titration technique (GITT) and electrochemical impedance spectroscopy (EIS) study confirm that [Cu(pyttz)2]PMo12@CGB (n, n=1, 2, 3) integrates the advantage of high electronic conductivity of CGB and excellent Li+ migration kinetics of POMs, which greatly ameliorates the electrochemical performances of POMs, among [Cu(pyttz)2]PMo12@CGB (2) exhibits an excellent reversible specific capacity of around 941.4 mA h g−1 at 0.1 A g−1 after 150 cycles and admirable rate performance. This work will promote the development of POMCP anodes, thus fulfilling their potential in high‐performance LIBs.
