Abstract
Thin films of garnet-type Li7La3Zr2O12 (LLZ) were prepared for the application of all-solid-state thin film lithium batteries. Thin films were prepared by a dip-coating process using a precursor sol from Zr-alkoxide and Li and La nitrates. The thin film of polycrystalline cubic LLZ with a thickness of about 800 nm was obtained after sintering at 900 degree with Li2CO3 powder.
