Tetrachloroaluminate [AlCl₄]⁻ is an anion formed from aluminium and chlorine. The anion has a tetrahedral shape, similar to carbon tetrachloride where carbon is replaced with aluminium. Some tetrachloroaluminates are soluble in organic solvents, creating an ionic non-aqueous solution, making them suitable as component of electrolytes for batteries. E.g. lithium tetrachloroaluminate is used in some lithium batteries.
