Conductivity of liquid lithium electrolytes with dispersed mesoporous silica particles

Soggy-sand effects in liquid composite electrolytes with mesoporous materials as fillers

“…This is one possible reason for the problems with the stabilization Journal of Materials Chemistry A Paper (Fig. 3b) of the soggy-sand dispersion containing mesoporous SiO 2 described in the publication of Sann et al 31 The low absolute values of the zeta potential additionally indicate that the ability for particles to adsorb ions is very low. Benzene groups are able to compete with the silanol groups at the particle surface in terms of ion adsorption even in the situation where the total tendency of ion dissociation is low.…”

“…24 In the context of such investigations, for a polyethylene glycol (PEG) system, an unexpectedly at relationship between conductivity and silica content was noticed and possible conductivity anomalies invoked. 29 In most recent publications, composite systems with Janus particles of two different functional groups 30 and mesoporous organosilica particles 31 have been investigated as soggy-sand llers. While in the case of Janus particles enhanced conductivities could be measured combined with less statistical particle arrangement of the silica particles in the formed clusters, with mesoporous organosilica particles it was reported that the dispersions are mechanically unstable and show in throughout lower conductivities than the particle-free electrolyte.…”
