In the synthesis of indium-based halide solid-state electrolytes—most notably lithium indium chloride (Li3InCl6)—indium(III) chloride (InCl3) serves as the primary structural network former. The trivalent indium ion (In^{3+}) coordinates with six chloride anions to build an octahedral [InCl6]^{3-} framework, providing a highly stable, low-barrier channel for Li+ superionic conduction. Because indium halide electrolytes balance high voltage compatibility (>4.0 V to 4.5 V vs. Li/Li+) with unique chemical reversibility, optimizing the InCl3 precursor is essential to maximizing phase purity and ionic conductivity.
Anhydrous Grade Requirement: Commercially available InCl3 exists commonly as a trihydrate (InCl3 * 3H2O) or a hygroscopic anhydrous powder. For solid-state or anhydrous organic solvent synthesis paths, anhydrous InCl3 (typically 99.99 % 4N purity trace metals basis) must be used. The Oxychloride (InOCl) Threat: If anhydrous InCl3 absorbs atmospheric moisture during storage or transfer, heating it in an attempt to dry it can cause an irreversible hydrolysis side-reaction rather than simple dehydration, where the indium oxychloride (InOCl) acts as an electrochemically inactive, insulating impurity phase within the electrolyte matrix, which drastically increases grain boundary resistance.
