X-ray scattering measurements were utilized to probe the effects of doping the neat 1-methyl-3-octylimidazolium bis (trifluoromethylsulfonyl) imide [C8mim][TFSI] room temperature ionic liquid with alkali-TFSI salts of varying concentrations. The introduction of lithium TFSI, sodium TFSI, potassium TFSI, rubidium TFSI and cesium TFSI has the universal effect on the scattering intensity of depressing the charge alternation peak and enhancing the aggregation peak as the relative concentration is increased. The changes in the liquid structure are interpreted as a result of the formation of long-lived alkali-TFSI complexes. The depression of the charge alternation peak is due to a more disordered structure at that length scale as the doping concentration increases. The aggregation peak is demonstrated to increase in height for all alkali complexes due to an increase in the scattering strength of the complexes and an increase in their prevalence as the concentration of each alkali salt is increased.

X射线散射测量用于探测用不同浓度的碱-TFSI盐掺杂纯净的1-甲基-3-辛基咪唑双（三氟甲基磺酰基）酰亚胺[C8mim] [TFSI]室温离子液体的效果。TFSI锂，TFSI钠钠，TFSI钾钾，rub TFSI和铯TFSI的引入对散射强度具有普遍影响，随着相对浓度的增加，散射强度降低了电荷交替峰并增强了聚集峰。液体结构的变化被解释为形成了长寿命的碱-TFSI配合物。电荷交替峰的降低是由于随着掺杂浓度的增加，在该长度尺度上结构更加混乱。
