Anomalous properties of molten alkali nitrates coexisting with aluminum oxides by hetero-phase effect

Intermediate temperature fuel cell with a doped ceria–carbonate composite electrolyte

“…The structure of the solid oxide phase influences the thermal and ionic conduction property of the molten carbonate. Such effects has been found in many molten salts, such as alkali nitrates [23], and alkali binary carbonate [24], coexisting with oxide powders such as LiAlO 2 , ZrO 2 , MgO, Al 2 O 3 , and SiO 2 [23][24][25][26]. This has been explained as the interfacial effect or interaction between the two phases.…”

Solvent molecule mobilities in propylene carbonate-based electrolyte solutions coexisting with fumed oxide nanoparticles

“…Various studies have reported that the physical properties of a liquid in the neighborhood of a solid surface differ from those of the bulk solution [4][5][6][7][8]. Specifically, the physical properties of the solvent molecules within the pores of a porous material with a layered structure are very different from those in the bulk phase as a result of the extremely small pore volume and large specific surface area [9][10][11].…”

“…Yamada et al have reported that highly concentrated electrolytes improved the charge efficiency and breakdown voltage of LIBs [18]. Various measurement techniques such as thermodynamic measurements [5,19,20], spectrophotometric methods (e.g., Infrared and Raman spectrometries [6,19,[21][22][23][24], neutron scattering method [25], and X-ray scattering measurements [26]), and electrochemical measurement (e.g., electric conductivity measurement [7,19] and electrochemical impedance spectroscopy) has been used so far. Herein, we focus on NMR measurements in particular.…”

Dynamic Properties on NMR Spectroscopy of Non-Aqueous Electrolyte Solution Coexisting with Fumed Silica Dispersion

“…However, with the diversification of the use, batteries which have higher capacity and can stand up to high speed charge/discharge than those of LIBs are demanded. Various studies have reported that the liquid phase among solid particles has a different structure from the original their properties of bulk solution (1)(2)(3). Thus solidliquid interface is performed as a base in charge-discharge of LIBs, an elucidation of liquid phase properties of solid-liquid interface in the non-aqueous electrolyte solution system is important for improving the performance of energy storage devices such as LIBs.…”
