The Effect of Sn-Doped Li7La3Zr2O12 on the Structure and Electrical Properties of Electrolyte Material for Li-Ion Batteries

Article Preview

Abstract:

High purity of Li7La3Zr2-xSnxO12 (x = 0.00, 0.50, 1.00, 1.50 and 1.00) samples that formed garnet-type crystal structure were prepared using biopolymer sol-gel method. The structure phase of Li7La3Zr2-xSnxO12 (x = 0.00, 0.50, 1.00, 1.50 and 1.00) powder was indexed with the parent composition of Li7La3Zr2O12 structure with space group of Ia-3d for cubic phase. Impedance spectroscopy analysis was used to determine the conductivity of Li7La3Zr2-xSnxO12 (x = 0.00, 0.50, 1.00, 1.50 and 1.00) samples. The samples exhibit the conductivity about 10-6 to 10-4 Scm-1 .The SEM micrographs reveal that the grain of the samples exhibits well developed particles of irregular shape.
