Abstract

Li-intercalated layered perovskites Li_xAB₂Na_n-3Nb_nO_3n+1 (A = K, Rb, Cs; B = Ca, Sr, Ba) with n = 3 and 4 have been prepared by an electrochemical technique. For the Li_xAB₂Nb₃O₁₀ superconducting materials, the value of T_c has been found to increase up to about 5-6 K as the a-axis length increases. For Li_xCsBa₂Nb₃O₁₀ with the largest a-axis length, however, superconductivity does not appear. In addtion, Li_xKCa₂NaNb₄O₁₃ shows no superconductivity.
