High Conductivity Electrolyte: Zn_2GeO_4

摘要

Zn_2GeO_4 ceramic materials were synthesized by the solid-state method. Zn_2GeO_4 powders were investigated with X-ray powder diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM). Oxygen defects in the Zn_2GeO_4 ceramics were investigated by photoluminescence, Raman, and EDS spectra. Conductivity of Zn_2GeO_4 was 0.18 S/cm at low temperature of 773 K, and its activation energy was 0.49 ev. The results showed that Zn_2GeO_4 was a promising low-temperature electrolyte with high conductivity.
