    摘要： A non-aqueous electrolyte secondary battery is provided that uses as a positive electrode active material a low-cost lithium-containing transition metal composite oxide containing Ni and Mn as its main components, to improve the output power characteristics so that it can be used suitably for an electric power source for, for example, hybrid electric vehicles. A non-aqueous electrolyte secondary battery has a positive electrode (11) containing a positive electrode active material, a negative electrode (12) containing a negative electrode active material, and a non-aqueous electrolyte solution (14) in which a solute is dissolved in a non-aqueous solvent. In the positive electrode active material, Nb2O5 in which the amount of niobium is 0.5 mol % with respect to the total amount of the transition metals and TiO2 in which the amount of titanium is 0.5 mol % with respect to the total amount of the transition metals are disposed on a surface of Li1.06Ni10.56Mn10.38O2.

    摘要： A positive electrode active material of a nonaqueous electrolyte secondary battery is improved by using an inexpensive lithium transition metal oxide containing nickel and manganese as main components. Output characteristics of the battery under various temperature conditions are thereby improved, and the battery is suitable as a power supply of a hybrid vehicle. The battery includes a positive electrode including a positive electrode active material, a negative electrode including a negative electrode active material, and a nonaqueous electrolyte prepared by dissolving a solute in a nonaqueous solvent. The positive electrode active material includes positive electrode active material particles composed of a lithium transition metal complex oxide having a layered structure containing nickel and manganese as main components, and at least one niobium-containing material selected from a Li—Nb—O compound and a Li—Ni—Nb—O compound, the at least one niobium-containing material being sintered onto surfaces of the positive electrode active material particles.
