X‐ray total scattering is applied to a series of molecular liquids including the CsF salt, which is expected to be a promising electrolyte in fluoride shuttle batteries. These electrolytes are composed of solvent molecules and addition agents (AAs), together with CsF. Tetraglyme (G4) or γ‐butyrolactone (GBL) is used as a solvent molecule, and lithium bis(fluorosulfonyl)imide (LiFSI), lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), triphenylboroxine (TPhBX), or lithium bis(oxaloto)borate (LiBOB) as an AA. It is found that an additional peak appears on the low‐Q side of the main peak by the addition of LiFSI, LiTFSI, or TPhBX to the solvent, which indicates that correlation between cation and anion molecules is induced by these AAs. Furthermore, the position and the intensity of this peak are changed by the addition of the CsF salt, suggesting the modification of the correlation in the presence of the Cs+ and F− ions.

液态氟穿梭电池中电解质的X射线总散射：低Q峰对电解质成分的依赖性
X射线总散射应用于包括CsF盐在内的一系列分子液体，CsF盐有望在氟化物穿梭电池中成为有希望的电解质。这些电解质由溶剂分子和加成剂（AAs）以及CsF组成。使用Tetraglyme（G4）或γ-丁内酯（GBL）作为溶剂分子，双（氟磺酰基）酰亚胺锂（LiFSI），双（三氟甲磺酰基）酰亚胺锂（LiTFSI），三苯基环硼氧烷（TPhBX）或双（草酸锂）硼酸（LiBOB）作为AA。发现在低Q上出现了另一个峰通过在溶剂中添加LiFSI，LiTFSI或TPhBX，可以在主峰的另一侧形成峰，这表明这些AA诱导了阳离子和阴离子分子之间的相关性。此外，位置和该峰的强度通过添加脑脊液盐的改变，这表明在Cs的存在的相关性的修改+和F -离子。
