Lithium ion conductors based on the perovskite La23–xLi3xTiO3

Reflection spectra and the parameters of dispersion oscillators of the perovskites La23–xM3xTiO3, where M is Li, Na, K are presented in the paper. In the case when M is Li the above perovskites exhibit high lithium ion conductivity. The origins of the lithium ion conductivity in the materials of the system La23–xLi3xTiO3 are discussed on the grounds is of both the research data obtained and the reference data.
