SRISM方法在高密度原始模型电解质双电层电容研究中的应用

Application of the SRISM approach to the study of the capacitance of the double layer of a high density primitive model electrolyte

S. Woelki, D. Henderson

摘要:

在这项研究中,单重参考相互作用网站模型(SRISM)的研究电极电荷的平面双电层电容的依赖性使用的原始模型的双电层的高密度电解质,模仿离子液体。离子由带电的硬球表示,电极是均匀带电的平坦表面。该模型流体的电容计算与SRISM方法与封闭的基础上超网链(HNC)和Kovalenko-Hirata(KH)封闭和模拟比较。只要电极电荷的大小不是太大,HNC闭合显示出最有希望。KH结果对于高密度电解质是相当好的,但是当在低密度下应用时是差的。

英文摘要:

In this study the Singlet Reference Interaction Site Model (SRISM) is employed to the study of the electrode charge dependence of the capacitance of a planar electric double layer using the primitive model of the double layer for a high density electrolyte that mimics an ionic liquid. The ions are represented by charged hard spheres and the electrode is a uniformly charged flat surface. The capacitance of this model fluid is calculated with the SRISM approach with closures based on the hypernetted chain (HNC) and Kovalenko-Hirata (KH) closures and compared with simulations. As long as the magnitude of the electrode charge is not too great, the HNC closure shows the most promise. The KH results are reasonably good for a high density electrolyte but are poor when applied at low densities.
