Lithium hexafluorozirconate is an inorganic compound of lithium, fluorine, and zirconium with the chemical formula Li2ZrF6.[2][3][4] It is the lithium salt of hexafluorozirconic acid.

Lithium hexafluorozirconate forms tetragonal crystals under standard conditions;[1] a monoclinic phase has been observed under high pressure.[5]

Preparation

Lithium hexafluorozirconate can be prepared by treating lithium fluoride with hexafluorozirconic acid solution.[6]

Uses

Lithium hexafluorozirconate is of research interest as an electrolyte in lithium metal batteries.[7] The in situ formation of a trigonal Li2ZrF6 solid–electrolyte interphase was reported to enhance Li-ion transfer and suppress the growth of Li dendrites.[7]
