ELECTRODE MIXTURE FOR SODIUM ION BATTERIES, PRODUCTION METHOD THEREFOR, AND ALL-SOLID-STATE SODIUM BATTERY

摘要

This electrode mixture for sodium ion secondary batteries is characterized by including active-material crystals, sodium-ion conductive crystals, and an amorphous phase. The active-material crystals preferably include Na, M (M being at least one transition metal selected from Cr, Fe, Mn, Co, and Ni), P, and O.
