“…Castejon et al [16] made a simulation with a wide range of typical cations and anions obtaining different ILs with good surface-wetting properties on silica, with contact angle values far below 90°. Delcheva et al [17] did a literature review on ionic liquid wettability finding that issues such as water content and halide impurities in combination with type of material and surface finish provoke uncertainty in the role of the ion chemistry. Carrera et al [18] found that a proper combination of ion structures is fundamental in order to modify the contact angle on Teflon and glass.…”

The wetting and corrosion behavior of three bis(trifluoromethylsulfonyl)imide-based ionic liquids: 1-Dodecyl-3-methylimidazolium bis (trifluoromethylsulfonyl) ]/TiN resulted as the best IL-surface combination for a good wettability, due to the higher dispersion of the charge on the large size cation in this IL and the higher values of total and polar component of the surface free energy for this coating. Finally, SEM-EDS analysis determined that [N 1888 ][NTf 2 ]/ZrN was the best option in order to avoid corrosion problems. The evaporation of water, present as impurity in the ionic liquids, was found the main reason because of corrosion did not occur in the tests carried out at 100 ºC.

A Plastic–Crystal Electrolyte Interphase for All‐Solid‐State Sodium Batteries

et al. 2017

The development of all-solid-state rechargeable batteries is plagued by a large interfacial resistance between a solid cathode and a solid electrolyte that increases with each charge-discharge cycle. The introduction of a plastic-crystal electrolyte interphase between a solid electrolyte and solid cathode particles reduces the interfacial resistance, increases the cycle life, and allows a high rate performance. Comparison of solid-state sodium cells with 1) solid electrolyte Na Zr (Si PO ) particles versus 2) plastic-crystal electrolyte in the cathode composites shows that the former suffers from a huge irreversible capacity loss on cycling whereas the latter exhibits a dramatically improved electrochemical performance with retention of capacity for over 100 cycles and cycling at 5 C rate. The application of a plastic-crystal electrolyte interphase between a solid electrolyte and a solid cathode may be extended to other all-solid-state battery cells.

“…Analyzing the results obtained, it is possible to discern a trend for all surfaces studied: [P 66614 ][(iC8) 2 PO 2 ] and [P 66614 ][BEHP] had the highest values, thus having the best wettability on hydrophobic surfaces. Furthermore, the differences between ILs were more noticeable in the most hydrophobic surfaces (CrN and ZrN), thus making a comparison more difficult for the less hydrophobic one Table 7.…”

“…8 One of the main advantages of working with ILs is the possibility of easily adapting their properties with small variations in the chemical composition, thus having a huge potential for engineering applications. 2 This fact may be used as a tool for self-tuning the ILs with multiple and useful application possibilities by changing physicochemical properties, such as density, melting point, viscosity, conductivity, or surface tension. 9 For instance, water miscibility of ILs is usually controlled by the anion, although the cation can also affect the hydrophobicity of the substance.…”
