Outline of Final Research Achievements	In this study, battery-related materials for next generation had been synthesized and examined thermal stability using high-temperature XRD associated with TG-DTA. Well-known lithium compound (lithium peroxide) which is the related compound for Li-Air battery, is stable up to around 200 degC under various condition as irreversible reaction. It suggests peroxide ion is decomposed at the temperature, and also the temperature is upper limit for the battery use.
