    摘要: A nonaqueous electrolyte secondary battery disclosed in the present application includes: a positive electrode capable of absorbing and releasing lithium, containing a positive electrode active material composed of a lithium-containing transition metal oxide having a layered crystalline structure; and a negative electrode capable of absorbing and releasing lithium, containing a negative electrode active material composed of a lithium-containing transition metal oxide obtained by substituting some of Ti element of a lithium-containing titanium oxide having a spinel crystalline structure with one or more element different from Ti, wherein a retention of the negative electrode is set to be greater than a retention of the positive electrode, and an irreversible capacity rate of the negative electrode is set to be greater than an irreversible capacity rate of the positive electrode, whereby a discharge ends by negative electrode limitation.
