Rechargeable (secondary) all-solid-state lithium batteries are considered to be the next generation high performance power sources and are believed to solve safety issues existing in the current lithium ion batteries with liquid electrolytes. A newly developed inorganic solid state electrolyte material, Li7La3Zr2O12 (LLZO) with garnet structure has attracted increasing attention over the past few years due to its superior properties, such as chemical stability against reactions with lithium metal electrode, high lithium ion conductivity, good thermal and environmental benignity.
Spark plasma sintering method is a combination of uniaxial pressing process and a direct passing of electric DC current through the graphite tool to sinter the material, if the powder is not electrically conductive.
In this work, SPS is applied for the first time to fabricate the lithium ion conducting LLZO. The effect of sintering temperature on the phase compositions, microstructure and density of the sintered-body compacts is investigated.
