Communication-Fast Li+ Ion Conducting NASICON-Type Li1.15Y0.15Zr1.85P3O12 Glass Ceramics

Herein, NASICON-type Li1.15Y0.15Zr1.85P3O12 glass ceramics (a-LYZP) were synthesized from amorphous materials. Compared with samples prepared by the solid-state reaction (s-LYZP), a-LYZP showed a higher total ionic conductivity of 7.0 x 10(-5) S cm(-1) at 298 K and improved inter-particle contact. The structure of this glass ceramic effectively reduced the resistance of the Li1.15Y0.15Zr1.85P3O12. In the temperature range 263-298 K, the activation energy of a-LYZP was 0.43 eV, which was smaller than that for s-LYZP (0.63 eV). Rietveld analysis of XRD patterns suggested that the longer a-axis and larger unit lattice volume of a-LYZP prevented phase change from rhombohedral to triclinic.
