The diffusion processes of lithium ions in Li5La3Ta2O12based electrolytes were investigated by internal friction (IF) method. Prominent relaxation-type IF peaks (actually consisted of two components) in Li5La3Ta2O12were observed: peak P1at lower temperature and peak P2at higher temperature. The relaxation parameters for the IF peaks are evaluated as E1=0.81eV, τ01=2×10−14s for peak P1and E2=0.87eV, τ02=7×10−14s for peak P2, respectively. After partial Ba substitution at La site (Li6BaLa2Ta2O12), peak P2decreases dramatically in height while peak P1does not change in height, but both peaks shift toward lower temperature. The mechanism of the P1and P2peak is suggested to be associated with two diffusion processes of lithium ions: 48g↔48g and 48g↔24d, respectively.
