Abstract
A method of manufacturing a non-aqueous electrolyte secondary battery by subjecting a sodium-magnesium-containing oxide represented by the general formula NaMgMO, where 0.65≦c≦0.75, 0<b≦0.3, 0≦a≦03, and M is at least one of manganese and cobalt, to ion-exchange of sodium for lithium by using a molten salt, an aqueous solution, or an organic solvent, to prepare a positive electrode active material.
