HPLC of Formula: 174501-65-6In 2021 ,《Surface charge density in electrical double layer capacitors with nanoscale cathode-anode separation》 was published in Journal of Physical Chemistry B. The article was written by Qing, Leying; Zhao, Shuangliang; Wang, Zhen-Gang. The article contains the following contents:
Using a dynamic d. functional theory, we study the charging dynamics, the final equilibrium structure, and the energy storage in an elec. double layer capacitor with nanoscale cathode-anode separation in a slit geometry. We derive a simple expression for the surface charge d. that naturally separates the effects of the charge polarization due to the ions from those due to the polarization of the dielec. medium and allows a more intuitive understanding of how the ion distribution within the cell affects the surface charge d. We find that charge neutrality in the half-cell does not hold during the dynamic charging process for any cathode-anode separation, and also does not hold at the final equilibrium state for small separations Therefore, the charge accumulation in the half-cell in general does not equal the surface charge d. The relationships between the surface charge d. and the charge accumulation within the half-cell are systematically investigated by tuning the electrolyte concentration, cathode-anode separation, and applied voltage. For high electrolyte concentrations, we observe charge inversion at which the charge accumulation exceeds the surface charge at special values of the separation In addition, we find that the energy d. has a maximum at intermediate electrolyte concentrations for a high applied voltage. The experimental process involved the reaction of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6HPLC of Formula: 174501-65-6)
3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6) is a member of lonic liquids. Actually, lonic liquids as innovative fluids have received wide attention only during the past two decades. The number of SCI papers published on lonic liquids has exponentially increased from a few in 1996 to >5000 in 2016, exceeding the annual growth rates of other popular scientific areas.
