Phase Transitions and Ion Conductivity in NASICON-type Compounds Li_(1±X)Zr_(2-X)M_(X)(PO_4)_3, M = Ta, Nb, Y, Sc, In
Abstract
Ionic conductivity and phase transitions of lithium-zirconium phosphates, Li_(1±X)Zr_(2-X)M_(X)(PO_4)_3 (M = Ta, Nb, Y, Sc, In), with NASICON structure were studied using X-ray powder diffraction, calorimetry, ^(31)P and ^(7)Li NMR and impedance spectroscopy. Triclinic-rhombohedral phase transition in these materials occurs in a wide temperature range at coexistence of both phases. Unusual change of LiZr_2(PO_4)_3 lattice parameters with temperature increase was found. During heating of this compound parameter "a" significantly decreases.
