AbstractLi+ ion-doped BaTiO3 (LBT-x, x=0, 3%, 5%, 7%) ceramics were prepared by the solid-state reaction method, which were analyzed by XRD and EDS. The Ba2TiO4 phase was formed on the surface of sintered LBT-x ceramics with high Li+ concentration (x=5%, 7%), and tetragonal phase appeared after the removal of Ba2TiO4 surface layer. According to the results from first-principle calculation of 2x2x2 and 3x3x3 supercells, Li+ ions can occupy B site of ABO(3) perovskite structure. The LBT-x (x=3%, 5%, 7%) ceramics showed antiferroelectric-like double hysteresis loops which form [Li-Ti-V-o](-) dipoles and pin the domain walls. The piezoelectric constant d(33) also decreases due to pinning effect.
