Extrinsic pseudocapacitive ultrathin 2D MoS₂ nanoflakes clamped on 1D Sb₂S₃ nanorods: an advanced heterostructured anode for high-energy ammonium ion hybrid capacitors

Abstract

Ammonium-ion (NH4+) charge carriers have recently been considered promising for the electrochemical energy storage (EES) system because of their high safety, low molar mass, and small hydrated radius (3.31 A˚)....

“…The EIS spectra were unaltered before and after 10000 cycles with small variations in the low-frequency region (Figure g) . Also, in another report, Marje et al used a double hydrothermal method to synthesize the unique 1D/2D interconnected structure of Sb 2 S 3 /MoS 2 . The MoS 2 nanosheets wrapped on the Sb 2 S 3 nanorods (Figure h) presented abundant reaction sites and large interlamellar galleries which promote the interfacial dynamics of ions during charging/discharging.…”

The XRD analysis and TEM micrographs show the formation of the Sb 2 S 3 /MoS 2 heterostructure well-illustrated in Figure 10i V) displayed reduction/oxidation regions, where the polarization curves shifted at higher scan rates (Figure 10l).…”

“…The advancement of NH 4 + energy storage technology remains in its early research phase, with a primary focus on designing electrode materials that offer both high specific capacity and affordability. Recent years have witnessed extensive exploration into various electrode materials, electrolytes, and devices tailored for NH 4 + storage, as illustrated by the notable progress depicted in Figure b. − …”
