摘要：
A positive electrode active material for alkali-ion secondary batteries is provided which contains 20-55% of Na2O+Li2O, 10-60% of CrO+FeO+MnO+CoO+NiO, and 20-55% of P2O5+SiO2+B2O3 in terms of oxide-equivalent mol % and includes 50 mass % or more of an amorphous phase. According to the present invention, it is possible to provide a positive electrode active material for alkali-ion secondary batteries that enables high energy density and is excellent in the charge and discharge characteristics.
