Properties of lithium ion-conducting ceramics based on rare-earth titanates

The properties of complex oxides with perovskite structure of the Ln_2/3−XM_3XTiO₃ type (where Ln = rare-earth element and M = Li, Na, K) have been investigated. It has been shown that lithium - containing perovskites possess cationic conductivity, with values depending on the size of conducting channels and the concentration of vacant sites in the rare-earth ion sublattice.
