Abstract

(LiCl)₂-Ga₂O₃-SiO₂ xerogels were prepared by a sol-gel process. Similar to that of the corresponding lithium aluminosilicate xerogels, the ionic conductivity of lithium gallosilicate xerogels increases with increasing Ga₂O₃/SiO₂ ratio for samples with the same lithium content (25 mol% (LiCl)₂) due to the increasing concentration of mobile lithium ions associated with tetrahedral GaO₄ or non-bridging oxygens in the xerogel. The conductivity increases with increasing (LiCl)₂ content for samples with a Ga₂O₃/SiO₂ ratio of 1 2 due to the combined effect of increasing preexponential factor and decreasing activation energy.
