“…Similar to the V 2 O 5 electrode with dual effects of oxygen vacancies and phosphorus doping we discussed above, oxygen defects and phosphate groups (H 2 PO 4 − and PO 3 − ) were simultaneously brought into (Na,Co)V 8 O 20 nanobelts (denoted as P‐Co‐NVO d ). [ 96 ] P‐Co‐NVO d showed an increased interlayer spacing due to the twisted (40‐1) plane and cavity formed within adjacent layers (Figure 15b), leading to additional Zn 2+ storage sites and reduced interaction between Zn 2+ and host. Phosphorous groups played an important role in maintaining the structural stability.…”

“…[94,95] For example, oxygen-deficient V 2 O 5 was achieved by placing NaBH 4 and V 2 O 5 on both sides of the porcelain boat with NaBH 4 on the upstream side of the tube furnace under 400 °C for 1 h. [92] Oxygen defects and phosphate groups in (Na,Co)V 8 O 20 nanobelts were simultaneously introduced via heat treatment at 300 °C in the presence of NaH 2 PO 2 H 2 O.

However, the organic electrolytes used in LIBs are highly toxic and flammable, and are deemed safety hazards. The limited resources and high-cost of lithium and harsh assemble conditions of LIB cells also hinder the application of LIBs in large-scale energy storage systems. [2] P. Rüetschi proposed the '3 E' criteria including Energy, Economics, and Environment to determine whether the battery system was practical for daily use. [3] Aqueous electrolytes with low price, high safety, and high conductivity can drastically reduce the production cost and improve battery safety. [4] Aqueous zincion batteries (ZIBs) use Zinc as an environment-friendly anode which shows low redox potential (−0.78 eV vs SHE), high electronic conductivity as well as large capacity (820 mAh g −1 and 5851 mAh cm −3 ). [5,6] Therefore, ZIBs are considered as one of the most competitive and promising development directions for next-generation large-scale energy storage. As the initial work in mild aqueous electrolyte, an aqueous ZIB with MnO 2 cathode and Zn anode was reported by Kang and co-workers in 2012. [7] Since then, research interests in ZIBs area develops burgeoningly and more than 1000 research papers about electrode materials on aqueous ZIBs were published.The commonly reported cathode materials are V-based compounds, [8,9] manganese oxides, [10,11] Prussian blue analogs, [12,13] metal chalcogenides, [14,15] and organic compounds. [16,17] Among them, manganese oxides have moderate operating potential and high theoretical capacity, but suffer from manganese dissolution in aqueous electrolytes due to Jahn-Teller dissolution of Mn 3+ , which leads to structural collapse and poor cycling stability. [10,11] Prussian blue analogs often process high operating potential beyond 1.5 V and their open cage-like framework guarantees structure stability under rapid Zn 2+ transmission, leading to good rate performance and long-cycle capacity retention. However, the large framework structures also bring limited theoretical capacity and suffer from O 2 evolution due to the high operating potential. [13,18] Organic cathodes process passable theoretical capacity, high structural diversity, and flexibility, bringing potential prospects in flexible electrodes. But the high dissolubility in electrolytes and high resistance are two bumps to overcome for organic cathodes used in ZIBs. [16,17] V-based compounds have received extensive attention as cathode for ZIBs due to the rich reserves and diversity of valences of vanadium as well as their general high theoretical capacity and Aqueous zinc-ion batteries (ZIBs) have been promptly developed as a competitive and promising system for future large-scale energy storage. In recent years, vanadium (V)-based compounds, with diversity of valences and high electrochemical-activity, have been widely studied as cathodes for aqueous ZIBs because of their rich reserves and high theoretical capacity. However, the stubborn issues including low conductivity and sluggish kinetics, plague their smooth application in aqueous...

Doped ceria-based metal oxides are widely used as supports and stand-alone catalysts in reactions where CO2 is involved. Thus, it is important to understand how to tailor their CO2 adsorption behavior. In this work, steering the CO2 activation behavior of Ce–La–Cu–O ternary oxide surfaces through the combined effect of chemical and mechanical strain was thoroughly examined using both experimental and ab initio modeling approaches. Doping with aliovalent metal cations (La3+ or La3+/Cu2+) and post-synthetic ball milling were considered as the origin of the chemical and mechanical strain of CeO2, respectively. Experimentally, microwave-assisted reflux-prepared Ce–La–Cu–O ternary oxides were imposed into mechanical forces to tune the structure, redox ability, defects, and CO2 surface adsorption properties; the latter were used as key descriptors. The purpose was to decouple the combined effect of the chemical strain (εC) and mechanical strain (εM) on the modification of the Ce–La–Cu–O surface reactivity toward CO2 activation. During the ab initio calculations, the stability (energy of formation, E Ov f) of different configurations of oxygen vacant sites (Ov) was assessed under biaxial tensile strain (ε > 0) and compressive strain (ε < 0), whereas the CO2-philicity of the surface was assessed at different levels of the imposed mechanical strain. The E Ov f values were found to decrease with increasing tensile strain. The Ce–La–Cu–O(111) surface exhibited the lowest E Ov f values for the single subsurface sites, implying that Ov may occur spontaneously upon Cu addition. The mobility of the surface and bulk oxygen anions in the lattice contributing to the Ov population was measured using 16O/18O transient isothermal isotopic exchange experiments; the maximum in the dynamic rate of 16O18O formation, R max(16O18O), was 13.1 and 8.5 μmol g–1 s–1 for pristine (chemically strained) and dry ball-milled (chemically and mechanically strained) oxides, respectively. The CO2 activation pathway (redox vs associative) was experimentally probed using in situ diffuse reflectance infrared Fourier transform spectroscopy. It was demonstrated that the mechanical strain increased up to 6 times the CO2 adsorption sites, though reducing their thermal stability. This result supports the mechanical actuation of the “carbonate”-bound species; the latter was in agreement with the density functional theory (DFT)-calculated C–O bond lengths and O–C–O angles. Ab initio studies shed light on the CO2 adsorption energy (E ads), suggesting a covalent bonding which is enhanced in the presence of doping and under tensile strain. Bader charge analysis probed the adsorbate/surface charge distribution and illustrated that CO2 interacts with the dual sites (acidic and basic ones) on the surface, leading to the formation of bidentate carbonate species. Density of states (DOS) studies revealed a significant E g drop in the presence of double Ov and compressive strain, a finding with design implications in covalent type of interactions. To bridge this study ...

“…[1][2][3] As an important component of ZIBs, electrolytes play a vital role in the electrochemical properties of ZIBs, as they provide a pathway for the migration of the zinc ions between the cathode and anode, and determine the electrochemical potential window, the Zn plating/stripping processes, the reaction mechanisms, and the ionic conductivity. [4][5][6][7][8] Furthermore, the selection of electrolytes is vitally important for the accurate evaluation of electrode materials and the achievement of superior electrochemical performance. Aqueous electrolytes are dominating the research in ZIBs, due to their low cost, high safety, environmental friendliness, and excellent ionic conductivity.…”
