Solid-State Synthesis and Characterization of Li_7-3xGa_xLa₃Zr₂O₁₂ Solid Electrolyte for Li-Ion Battery Application

Abstract:

Conventional solid-state synthesis of Li_7-3xGa_xLa₃Zr₂O₁₂ (LLZ) at x = 0.0 and 0.1 were performed in an attempt to investigate the microstructural and electrochemical properties of pure and Ga-doped LLZ as solid electrolyte material. The XRD patterns have shown that upon sintering at 1150°C the cubic-phased garnet LLZ were fully stabilized. Ga-doped LLZ exhibited a Li-ion conductivity up to 2.03 x 10^-4 Scm^-1 at 25°C. The relative densities of the pure and Ga-doped LLZ sintered at 1150°C for 15 h are 87.62% and 88.79%, respectively. This suggests that Ga dopant, even at small amount of x = 0.1, promotes densification. SEM-EDS confirmed the presence of Ga and homogenous distribution of elements in the synthesized material.
