Laser-radiated tellurium vacancies enable high-performance telluride molybdenum anode for aqueous zinc-ion batteries

Interfacial Coupling FeSe2/MoS2 Heterostructure as a Promising Cathode for Aluminum-Ion Batteries

“…It is observed that the heterostructured FeSe 2 /MoS 2 cathode delivers a smaller resistance (R ct = 60 Ω) than that of the FeSe 2 / MoS 2 mixture cathode (R ct = 114 Ω), verifying the high charge/ ion conductivity and stable interfacial contact between electrode and electrolyte. 49,50 The fast reaction kinetics of the heterostructured FeSe 2 /MoS 2 could be attributed to its strong charge-redistribution capability provided by the built-in electric field as shown in Figure 4b. Besides, the charge-storage mechanism of the heterostructured FeSe 2 /MoS 2 cathode was studied by XPS analysis.…”

Modification of 2D materials using MoS2as a model for investigating the Al-storage properties of diverse crystal facets

“…4b), the peaks shifted by 0.2 eV toward the high-binding-energy region at the full discharged state and returned to the original position after charging. This result again implies that the Al-based ions are intercalated in the electrode and electronic state interactions occur, 19,44 the details of which were further investigated. The spectra of Al 2p and Cl 2p at different potential states are displayed in Fig.…”

“…This multihole structure of S-MoS 2 with a larger surface area can offer abundant channels for ion transport and improve the kinetic process of ABs. 18,19 The elemental mapping images in Fig. S2 † indicate that Mo and S were uniformly distributed throughout the sample.…”

Practical conversion-type titanium telluride anodes for high-capacity long-lifespan rechargeable aqueous zinc batteries

“…21 With reference to the literature reports on the graphite anodes in LIBs, the metal-free anode is capable of bypassing the above challenge of Zn metal. 22 Despite sacricing some energy density, the higher redox potential of metal-free anodes relative to Zn metal makes them less susceptible to Zn plating, hydrogen evolution, and electrolyte decomposition, which indicates that metal-free anodes may be safer and more reversible than Zn metal. As reported by Cheng et al, an intercalation-type Mo 6 S 8 electrode in a half cell delivers an operating voltage of 0.7 V (vs. Zn 2+ /Zn) and retains a capacity as high as 60 mA h g À1 aer 150 cycles at 0.2 A g À1 .…”
