Non-aqueous electrolyte battery

A non-aqueous electrolyte battery comprising:

• a positive electrode having a positive electrode active material;
• a negative electrode that does not contain lithium prior to initial charge and discharge;
• and a non-aqueous electrolyte containing lithium, wherein the positive electrode active material comprises a lithium pre-doped transition metal oxide prepared by pre-doping lithium into a lithium-containing transition metal oxide having an initial charge-discharge efficiency of higher than 100%, as determined by charging and discharging using a lithium metal negative electrode as a counter electrode, wherein the lithium pre-doped transition metal oxide is represented by the compositional formula NaaLibMO2±α, where 0≦a<0.1, 0.5≦b≦1.2, 0≦α≦0.1, and M is at least selected from the group consisting of Ni, Co, and Mn.
