In recentry, sodium ion batteries are focused for next generation rare-metal free batteries. We proposed Na₂FeP₂O₇ cathode for sodium batterry and unique fabrication process that based on glass-ceramic process. However precise crystallization mechanism of glass is still uncleared. In this study we examined crystallization behavior of bulk Na₂FeP₂O₇ glass.
