Influence of organomodified laponite on ionic transport in nanocomposite polymer electrolytes based on polyethylene glycol and LiClO4

Abstract

The ionic association in nanocomposite polymer electrolytes based on polyether, lithium perchlorate and nanosized laponite was studied using the data of ionic conductivity and Fuoss-Kraus formalism. It was established that with increasing salt content, the conductivity of the electrolyte initially increases, reaching a maximum at 1-1.3 mol/kg with a subsequent decrease, which is associated with ionic association. It is found that increasing the temperature and the introduction of the filler increases the number of free ions, which leads to an increase in conductivity. The introduction of nanoclay into the polymer electrolytes leads to an increase in their electrical conductivity. This method of modification is can be used for the development of polymer electrolytes with improved functional characteristics for lithium current sources.
