| Popis: | A series of Nasicon-type solid electrolytes Li 1+2 x +2 y Al x Zn y Ti 2− x − y Si x P 3− x O 12 was synthesized by conventional solid state ceramic route. X-ray diffraction and Rietveld whole pattern refinement were applied to investigate the phase, structure and the unit cell parameters of those solid electrolytes. EIS complex impedance method was carried out to study the Li + conductivity. The results showed that Li 1+2 x +2 y Al x Zn y Ti 2− x − y Si x P 3− x O 12 with x =0.1 y =0.5 presents highest ionic conductivity 7.2×10 −5 S cm −1 at ambient temperature and 2.0×10 −3 S cm −1 at 473 K. The activation energy of Li + migration was calculated to be ca. 20 kJ mol −1 . The influence of Zn 2+ element on the structure and Li + mobility was preliminary explained. |
