Preparation and Performance Analysis of Composite Cathode Material SSC-YWO
The cathode material SSC-YWO was synthesized by solid-state method.The phase composition,thermogravimetric analysis,average valence state of Co and oxygen content of the material were studied.The results show that SSC and YWO have good chemical compatibility within 1 050℃.The loss of lattice oxygen and the formation of oxygen vacancies result in significant weight loss of the ma-terial at around 80℃.The average valence state and oxygen content of Co ions decrease with the increase of YWO content,while the ox-ygen vacancy concentration increases.
