Abstract

Li-Beta alumina exhibited higher ionic conductivity than other lithium aluminate phases of LiAl₅O₈, LiAlO₂ and Li₅AlO₄ because of the special crystal structure having many conduction channels in c-plane. It is usually used as solid electrolyte in Battery. Compared with bulk and powder, Li-Beta alumina film takes advantages of decrease in area specific resistance, reduction of operating temperature, reduction of size/weight for battery and enhancement of battery cycle life. Laser chemical vapour deposition is used to achieve the first synthesis of Li-Beta alumina in form of film, which exhibits a high conductivity of 5.96 S∙m^-1∙K at room temperature. In this process, the remained issue of Li loss is essential to be fixed for large-scale production.
