Chromium-Containing Li1.5Al0.5Ge1.5(PO4)3 Glass-Ceramics: Preparation and Electrical Conductivity
Abstract
Abstract The Li1.5 + хAl0.5CrxGe1.5 − xP3O12 − δ (x = 0–0.2) solid electrolytes for all-solid-state batteries were produced by glass crystallization. The products were identified by XRD as LiGe2(PO4)3-based NASICON solid solutions with various unit cell parameters. The total room-temperature Li+ conductivity of the prepared samples had similar values of about 10−4 S/cm. The Li1.6Al0.5Cr0.1Ge1.4P3O12 − δ composition exhibited the highest ionic conductivity of 3.43 × 10−4 and 4.26 × 10−3 S/cm at 25 and 100°C, respectively. The electronic conductivity as determined by the DC polarization method with blocking platinum electrodes, did not exceed 10−9 S/cm for all compositions studied.
