Abstract

Investigation of electrical properties inside double phosphates Na_8-2xM²⁺_4+x(P₂O₇)₄ containing simultaneously the Na⁺ ion and a divalent cation (M²⁺=Mn²⁺, Co²⁺, Ni²⁺) is undertaken by impedance spectroscopy. Ionic conductivity in these materials is due to Na⁺ ion mobility in tunnels along the c-axis centred on the (0,0,0) position. The best performance are obtained for the Co-phase. Correlations between structure and electrical properties are established.
