Mechano-chemical synthesis of crystalline superionic conductors CsAg4Br3-xI2+x (0

Abstract

Abstract Silver ion conductive materials attract numerous interest of research nowadays, due to their high potentiality in the solid electrolyte ion source (SEIS) intended for the application in the ionic thruster. In the work, mechano-chemical synthesis of crystalline superionic conductors CsAg4Br3-xI2+x (0<x<1) was performed by means of high-energy ball milling for the first time. The structure, morphology, and elemental composition were investigated and the effects of iodine content on these properties were studied. Silver-conducting properties were characterized based on the generation of Ag+ ion beams. The ion current of about 15 nA was obtained at 152°C and 15 kV.
