Abstract

We have synthesized and characterized new cesium-phosphate-based solid electrolytes with the general formula Cs3−4x M IV x PO4 (M = Zr, Hf, Ce) and high cesium ion conductivity. The increase in the conductivity of Cs3PO4 upon the introduction of the dopants studied is primarily due to the formation of cesium vacancies and the broadening of the stability range of the high-temperature phase of cesium phosphate, which has good transport properties.
