Lithium coordination in protic ionic liquids

Menne S, Vogl T, Balducci A

Abstract

The lithium ion-ion interactions in protic ionic liquids can be very different compared to the one of aprotic ionic liquids. In this study we show that, for equal lithium ion concentration, the lithium coordination number in protic ionic liquids is lower than that of aprotic one. This lower coordination makes lithium ions more "free" to move in protic ionic liquids and it might have important consequence of the lithium mobility.
