Abstract
We report the synthesis of high-quality cubic-phase Li7La3Zr2O12 powders using a solution based technique. Detailed structural, morphological, compositional and electrochemical characterization of the samples was performed. The lithium-ion conductivity of the cubic-phase Li7La3Zr2O12, determined by electrochemical impedance spectroscopy, was ∼1.67×10−4 S/cm. A proto-type all-solid-state battery with Li7La3Zr2O12 as electrolyte, LiCoO2 as cathode and a Lithium metal foil as anode was assembled. The cell was rechargeable and exhibited a very promising specific discharge capacity of 3.4 mAh/g which corresponds to 2.5% of the theoretical capacity. The above value is the highest discharge capacity reported till date using Li7La3Zr2O12 electrolyte.Keywords
