Abstract:
1. A method of manufacturing a non-aqueous electrolyte secondary battery, comprising the steps of: preparing a positive electrode active material comprising a lithium-containing sodium oxide in which the molar amount of lithium is less than the molar amount of sodium by sintering a material containing at least a sodium compound and a lithium compound; immersing the positive electrode active material in a non-aqueous electrolyte comprising a carbonate-based solvent containing a lithium salt to ion-exchange the sodium oxide; preparing a positive electrode active material slurry containing the positive electrode active material and a binder, and thereafter applying the positive electrode active material slurry to a positive electrode current collector, to prepare a positive electrode; interposing a separator between a negative electrode and the positive electrode to prepare a power-generating element; and enclosing the power generating element into a battery case, and filling an electrolyte solution into the battery case.
