Herein, we present a novel dual‐ion cell with a molybdenum disulfide (MoS2) anode, a graphite cathode, and a pure 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (EMImTFSI) electrolyte. During charging, the EMIm+ cations intercalate into the anode's MoS2 interlayers and the TFSI− anions synchronously penetrate into the cathode's graphite lattice. During discharging, both the cations and anions deintercalate from the electrodes. The reversible intercalation of EMIm+ into MoS2 is systematically evaluated by cyclic voltammetry, galvanostatic cycling, XRD, Raman, and SEM tests. The results reveal that within 0.5–3.6 V and at 0.5 C, the batteries present a high medium discharge plateau of ∼2.5 V, a decent discharge capacity of 77.0 mAh g−1, and a good energy density of 175.6 Wh kg−1; at 4 C, the cells exhibit a superior cyclability with 84.3 % capacity retention for 300 cycles and a high Coulombic efficiency of 96.1 %. Electrode characterizations indicate that both the MoS2 anode and the graphite cathode display a high stability over a long‐term cycling process. This novel cell configuration opens a new avenue to further develop promising rechargeable dual‐ion energy storage systems. A dual‐ion cell with an MoS2 anode, a graphite cathode, and a pure 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (EMImTFSI) electrolyte is presented. The cell exhibits a working voltage of ∼2.5 V, a discharge capacity of 77.0 mAh g−1, and an energy density of 175.6 Wh kg−1. Upon charging, the EMIm+ cations intercalate the MoS2 interlayers while the TFSI− ions penetrate the graphite cathode. Upon discharging, both the cations and anions deintercalate from the electrodes. It is shown that flake MoS2 displays a high stability for hosting EMIm+ over a long‐term cycling process. [ABSTRACT FROM AUTHOR]

The Eastern Tianshan orogen contains many late Paleozoic porphyry Cu and magmatic Cu-Ni deposits. Recent studies demonstrate that several early Paleozoic volcanogenic massive sulfide (VMS) Cu-polymetallic and porphyry Cu deposits were discovered in the northern part of Eastern Tianshan. This study presents zircon U-Pb, whole-rock geochemical, and Sr-Nd isotopic data for granites and diorites from the Huangtupo VMS Cu-Zn deposit, northern part of the Eastern Tianshan. Our results can provide constraints on the genesis of intermediate and felsic intrusions as well as early Paleozoic geodynamic setting of the northern part of Eastern Tianshan. LA-ICP-MS zircon U-Pb analyses suggest that the granites and diorites were formed at 435 ± 2 Ma and 440 ± 2 Ma, respectively. Geochemical characteristics suggest that the Huangtupo granites and diorites are metaluminous rocks, exhibiting typical subduction-related features such as enrichment in LILE and LREE and depletion in HFSE. The diorites have moderate Mg#, positive ε Nd (t) values (+6.4 to +7.3), and young Nd model ages, indicative of a depleted mantle origin. The granites exhibit mineral assemblages and geochemical characteristics of I-type granites, and they have positive ε Nd (t) values (+6.7 to +10.2) and young Nd model ages, suggesting a juvenile crust origin. The early Paleozoic VMS Cu-polymetallic and porphyry Cu deposits in the northern part of Eastern Tianshan were genetically related. The formation of the early Paleozoic magmatic rocks as well as VMS and porphyry Cu deposits in the northern part of Eastern Tianshan was due to a southward subduction of the Junggar oceanic plate.
