Positive electrode active material for sodium-ion secondary cell
摘要:
Provided is a novel positive electrode active material for a sodium-ion secondary cell having a good discharge capacity. A positive electrode active material for a sodium-ion secondary cell, the positive electrode active material containing, in terms of % by mole of oxide, 8 to 55% Na2O, 10 to 70% NiO, 0 to 60% CrO+FeO+MnO+CoO, and 15 to 70% P2O5+SiO2+B2O3 and containing an amorphous phase.
