Abstract

Synthesis and superconductivity of new Li-intercalated layered perovskites, Li_xSr₂CuO₂X₂ (X = Cl, Br, I) and Li_xAB₂M₃O₁₀ (A = K, Rb, Cs; B = Ca, Sr, Ba; M = Nb, Ta), are reviewed. Li-intercalation has been carried out by the electrochemical technique. First, layered cuprates Li_xSr₂CuO₂X₂ show superconductivity with T_c = 8.0 K and 4.5 K for X = Br and I, respectively. However, no superconductivity appears for X = Cl. Next, we have succeeded in preparing new superconductors, Li_xCsSr₂Nb₃O₁₀ with T_c = 5.5 K and Li_xRbSr₂Nb₃O₁₀ with T_c = 6 K. In the layered tantalates of Li_xCsSr₂Ta₃O₁₀, however, no superconductivity has been observed.
