In order to enhance energy density of NaMP₂O₇ cathode for sodium ion batteries, we examined glass formation and crstallization tendency as well as its electrochemical performance of NaMnP₂O₇ glass and glass-ceramics. It is found that layered NaMnP₂O₇ was formed just avebe glass transition temperature and then we observed irreversible phase transition into beta-Na₂MnP₂O₇ phase.
