Abstract:A series of LaxSr1-xMnO3 cathode powders were synthesized from materials mixed to different stoichiometric ratios by a hydrothermal method in this work. The crystal structure and microstructure of the powders were characterized by XRD, SEM and electrochemical analysis equipment. The results showed that LaxSr1-xMnO3 cathode powder of uniform size and typical perovskite structure can be obtained at the mineralizer KOH concentration of 4~6mol/L, reaction time of 50 hours and the temperature from 260~270 ℃.
