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

“…The Nyquist plots of the heterostructured FeSe 2 /MoS 2 and the FeSe 2 /MoS 2 Mixture cathodes are depicted in Figure a to explore the reaction kinetics. The value of the electrochemical impedance depends on the interfacial charge/ion transfer process and the properties of the SEI layer. , The corresponding equivalent circuit diagram is shown in Figure S2. 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. , 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 b.…”

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

“…The smaller R ct (2.3 Ω) of S–MoS 2 than that of MoS 2 (2.4 Ω) illustrates the enhanced conductivity and faster charge-transfer process. 38,39 Moreover, the ion-diffusion capacity of S–MoS 2 and MoS 2 were qualitatively measured according to formulas (1) and (2): 40,41 Z ′ = R ct + R e + σω −1/2 where R and T are the gas constant and temperature, respectively. A and n refer to the cathode area and number of electrons transferred during the reaction, respectively.…”

A Gradient Lithiophilic Structure for Stable Lithium Metal Anodes with Ultrahigh Rate and Ultradeep Capacity

“…The presence of Li x Zn could be inferred from the Zn 2p spectrum, which exhibited Zn 2p 1/2 and Zn 2p 3/2 peaks centered at 1044.6 and 1021.4 eV, respectively. [24] The Li 1s spectrum reveals peaks at 56.1 and 55.1 eV corresponding to Li 2 O and Li 0 , respectively. The formation of Li x Zn and Li 2 O confirm the formation of a highly Li-ion conductive layer on the surface of the Li@GSZO-CF electrode, providing an excellent pathway for Li-ion transfer during the Li plating/stripping process, thereby reducing Li plating polarization.…”

“…The SEI and charge transfer resistances are denoted as R int and R ct , respectively, while R tot is used to indicate the total interfacial resistance between the electrode and electrolyte. [24] Note that the bare Li plate has an initial R tot value of 859.69 Ω, which decreases significantly to 17.887 Ω after only 100 cycles with nearly zero SEI resistance (R int ), implying the Li dendrite formation and internal short-circuiting. Prior to cycling, Li@GSZO-CF exhibits a higher interfacial resistance (73.396 Ω) than Li@CF (62.99 Ω).…”
