Title: Structural, electrical and electrochemical properties of Li{sub 4}Zr{sub x}Si{sub 1-x}O{sub 4} (0.02 ≤ x ≤ 0.06) ceramic electrolytes

The aim of this work was to investigate the structural, electrical and electrochemical properties of Li{sub 4}Zr{sub x}Si{sub 1-x}O{sub 4} (0.02 ≤ x ≤ 0.06) compounds prepared via sol gel method. The X-ray Diffraction results showed that all compounds can be indexed to monoclinic structure in space group P2{sub 1/m}. The Li{sub 4}Zr{sub 0.06}Si{sub 0.94}O{sub 4} compound showed highest bulk, grain boundary and total conductivity values of 1.19 × 10{sup −4} S cm{sup −1}, 4.75 × 10{sup −5} S cm{sup −1} and 3.41 × 10{sup −5} S cm{sup −1} respectively. The insertion of Zr{sup 4+} is found to enhance conductivity of the parent sample Li{sub 4}SiO{sub 4}. Linear sweep voltammetry results showed that Li{sub 4}Zr{sub 0.06}Si{sub 0.94}O{sub 4} ceramic electrolytes was electrochemically stable up to 5.07 V versus a Li{sup +}/Li{sup +} reference electrode.
