摘要：
A positive electrode active material for sodium molten salt batteries includes a sodium-containing metal oxide that can electrochemically intercalate and deintercalate sodium ions, wherein a ratio by mass of sodium carbonate is 500 ppm or less. A ratio by mass of sodium carbonate in the positive electrode active material is more preferably 100 ppm or less.
