Abstract: A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The positive electrode includes lithium composite oxide particles A and B containing Ni and Mn. The lithium composite oxide particles A include secondary particles a2 that are aggregations of primary particles a1, and contain at least one of zirconium and boron. The lithium composite oxide particles B include at least one of primary particles b1 and secondary particles b2, the primary particles b1 having a larger particle size than the primary particles a1, the secondary particles b2 being aggregations of the primary particles b1 and having a smaller particle size than the secondary particles a2. The mass ratio of the lithium composite oxide particles A to the lithium composite oxide particles B is within the range of 8:2 to 4:6.

Abstract: A power storage device includes a stacked electrode assembly in which a plurality of pairs of electrodes are stacked and a fixing tape which is placed astride both end portions of the stacked electrode assembly in an electrode-stacking direction and which includes a pair of bonded sections each bonded to a corresponding one of the end portions thereof and an intermediate section connecting the bonded sections together. The intermediate section of the fixing tape includes a base portion extending along a side surface of the stacked electrode assembly and a clearance portion projecting in a direction away from the side surface of the stacked electrode assembly and tape surfaces facing each other in the clearance portion are separably bonded to each other.
