The electrical properties of amorphous thin solid films of Li1.3Al0.3Ti1.7 (PO4)3 (LATP) electrolyte deposited on stainless steel substrates via radio-frequency magnetron sputtering from LATP powder targets were studied. The results indicated that the LATP thin film electrolyte deposited in Ar-O2 atmosphere has a high ionic conductivity of 6.47106 S cm1 and a low electronic conductivity of 2.341014 S cm1. The easy fabrication of LATP thin films, high ionic conductivity together with the small electronic conductivity suggest that LATP thin films are promising as a candidate for solid electrolytes in all-solid-state thin film lithium batteries.
