摘要： The nonaqueous electrolyte secondary battery according to one aspect of the present invention includes a lithium-transition metal compound as a positive electrode active material that is capable of intercalating and deintercalating a lithium ion and is represented by Li1+aNixCOyMzO2 (wherein M is at least one element selected from Mn, Al, Ti, Zr, Nb, B, Mg and Mo; and 0≦a≦0.3, 0.1≦x≦1, 0≦y≦0.5, 0≦z≦0.9, a+x+y+z=1), and carbon as a negative electrode active material that is capable of intercalating and deintercalating a lithium ion and is added with a powder of a compound having an imide bond. In the nonaqueous electrolyte secondary battery of the present invention, by incorporating a compound having an imide bond, the initial efficiency of the negative electrode is lowered, so that at a low state of charge of 20% or less, an increasing rate of the IV resistance value becomes small. With such a constitution, a nonaqueous electrolyte secondary battery in which a change in the IV resistance value at a low state of charge is suppressed, which is excellent in output properties and regeneration properties, and which is suitable for an electric vehicle (EV) and a hybrid electric vehicle (HEV), for example, can be provided.
