Abstract Compared with Zn 2+ , the current mainly reported charge carrier for zinc hybrid capacitors, small-hydrated-sized and light-weight NH 4 + is expected as a better one to mediate cathodic interfacial electrochemical behaviors, yet has not been unraveled. Here we propose an -modulated cationic solvation strategy optimize spatial distribution achieve dynamic /NH co-storage boosting Zinc capacitors. Owing hierarchical solvated structure in Zn(CF 3 SO ) 2 –NH CF electrolyte, high-reactive small-hydrate-sized (H O) induce Helmholtz plane reconfiguration, thus effectively enhancing density activate 20% capacity enhancement. Furthermore, adsorbed hydrated ions afford high-kinetics ultrastable C‧‧‧H (NH storage process due much lower desolvation energy barrier compared heavy rigid Zn(H 6 (5.81 vs. 14.90 eV). Consequently, physical uptake multielectron redox of carbon cathode enable capacitor deliver high (240 mAh g −1 at 0.5 A ), large-current tolerance (130 50 ultralong lifespan (400,000 cycles). This study gives new insights into design cathode–electrolyte interfaces toward advanced zinc-based storage.

ConspectusZinc metal batteries (ZMBs) appear to be promising candidates replace lithium-ion owing their higher safety and lower cost. Moreover, natural reserves of Zn are abundant, being approximately 300 times greater than those Li. However, there some typical issues impeding the wide application ZMBs. Traditional inorganic cathodes exhibit an unsatisfactory cycling lifetime because structure collapse active materials dissolution. Apart from cathodes, organic now gaining extensive attention as ZMBs sustainability, high environmental friendliness, tunable molecule which make them usually superior life. Nevertheless, due inferior conductivity materials, mass loading volumetric energy density still cannot meet our demands. In addition, specific working mechanism inorganic/organic also needs further investigation, necessitating use advanced in situ characterization technologies. Reversibility metallic anodes is crucial determining overall cell performances. Like Li Na anodes, uncontrolled dendrite growth annoying problem for may penetrate separator cause inner short circuit. aqueous electrolyte, highly reactive H2O molecules easily attack anode, leading undesired corrosion. Furthermore, during operation, hydrogen evolution reaction (HER) occurs, leads continuous consumption electrolytes formation insulating byproducts on anodes. Although strategies like novel anode design artificial SEI layer construction proposed inhibit dendrites protect attack, corresponding manufacturing process remains complex. Modifying electrolyte components relatively simple implement effectively stabilizes HER completely eliminated when exists modified electrolytes. Under such conditions, nonaqueous a solution future aprotic nature stability with ionic low compared that Most previous reviews focus only individual A review perspective, focusing system design, currently lacking.In this Account, we begin brief overview ZMBs, highlighting advantages current challenges.

Room-temperature sodium–sulfur (RT Na–S) batteries with high energy density and low cost are considered promising next-generation electrochemical storage systems. However, their practical feasibility is seriously impeded by the shuttle effect of sodium polysulfide (NaPSs) resulting from sluggish reaction kinetics. Introducing a suitable catalyst to accelerate conversion NaPSs most used strategy inhibit effect. Traditional catalytic approaches often want avoid irreversible phase transition at deep discharge. On contrary, here, we leverage intrinsic structural tunability MoS2 in opposite direction innovatively propose voltage modulation for situ generation trace Mo single atoms (MoSAC) during first charge–discharge process, leading formation highly active phases (MoS2/MoSAC) through self-reconstruction. Theoretical calculations reveal that incorporation MoSAC modulates electronic structure d-band center, which not only effectively promotes d–p orbital hybridization but also accelerates intermediate desorption bonding transition, dynamic single-atom synergistic mechanism enhances adsorption response between metal site NaPSs, significantly improves sulfur redox (SRR), initial capacity MoS2/MoSAC/CF@S cell 0.2 A g–1 increased 46.58% compared MoS2/CF@S cell. The discovery MoS2/MoSAC/CF provides new insights into adjusting function disulfide catalysts atomic scale, offering hope development high-specific-energy RT Na–S batteries.

The aqueous zinc-ion battery (AZIB) is regarded as one of the most promising energy storage solutions. However, its widespread adoption hindered by challenges such zinc dendrite formation and undesirable side reactions, primarily caused excess free water molecules ions. This study introduces an ethylene oxide (PEO)-based gel electrolyte designed to address these limitations. By incorporating a zinc-rich ionic conductor (TP-Zn) that establishes cross-linked hydrogen bond network, we successfully reduce crystallinity PEO matrix enhance conductivity mechanical strength electrolyte. resulting PGPS@TP-Zn exhibits remarkable tensile deformation up 1785%. incorporation TP-Zn significantly alleviates interfacial between electrode, leading more uniform ion flux distribution.
