Di-metal element substitution of Al3+ and Ti4+ in improving electrochemical and structural behavior of ceramic solid electrolytes
Mechanical milling method is performed to prepare Li1+xAlxTixSn2-2xP3O12 (x = 0.2, 0.4, 0.6, 0.8) NASICON-based ceramic solid electrolyte at 650 oC. X-ray diffraction (XRD) showed that Li1.4Al0.4Ti0.4Sn1.2P3O12 has almost pure compound that is isostructural to LiSn2(PO4)(3) and the addition of Al3+...
