PURPOSE: A non-aqueous electrolyte battery is provided to enhance the battery capacity, and to improve the initial rechargeable efficiency of the battery. CONSTITUTION: A non-aqueous electrolyte battery comprises a positive electrode including a positive electrode active material, a negative electrode including a negative electrode active material without lithium before charging/discharging, and a non-aqueous electrolyte containing the lithium. The positive electrode active material is formed by predoping the lithium on a sodium-containing transition metal oxide with the initial rechargeable efficiency over 100% when charging/discharging by using a lithium metal negative electrode on an opposite electrode(2). |
