ELECTRODE ACTIVE MATERIAL, ELECTRODE, AND SODIUM SECONDARY BATTERY

摘要

The present invention provides an electrode active material, an electrode and a sodium secondary battery. The electrode active material contains the following powder (A) and powder (B): (A) a powder of a transition metal sodium phosphate, the powder having a BET specific surface area of from 1 m2/g to 100 m2/g, (B) a powder of a mixed metal oxide or a powder of a transition metal lithium phosphate or both. The electrode has the electrode active material. The non-aqueous electrolyte secondary battery has the electrode as a positive electrode.
