Atomic layer deposition (ALD) was used to control the stoichiometry of thin lithium aluminosilicate films, thereby enabling crystallization into the ion-conducting β-eucryptite LiAlSiO4 phase. Here, the rapid thermal annealed ALD film developed a well-defined epitaxial relationship to the silicon substrate: β-LiAlSiO4 ($$1\bar{21}0$$)||Si (100) and β-LiAlSiO4 ($$10\bar{10}$$)||Si (001). The extrapolated room temperature ionic conductivity was found to be 1.2 × 10–7 S/cm in the [$$1\bar{21}0$$] direction. Because of the unique 1-D channel along the c axis of β-LiAlSiO4, the epitaxial thin film has the potential to facilitate ionic transport if oriented with the c axis normal to the electrode surface, making it a promising electrolyte material for three-dimensional lithium-ion microbatteries.
