The positive and negative electrode plates are wound with the separator interposed therebetween. The positive electrode plate includes a first current collector exposed portion where a portion of the positive electrode current collector corresponding to an outermost portion of the electrode group is exposed over a length of greater than or equal to one turn in a winding direction of the electrode group, and a second current collector exposed portion where a portion of the positive electrode current collector corresponding to a middle portion of the electrode group is exposed over a length of greater than or equal to one turn in the winding direction. A positive electrode lead is provided on the second current collector exposed portion so as to be connected to an external electrode.

摘要： Disclosed is a positive electrode for non-aqueous electrolyte secondary batteries, the positive electrode including a positive electrode material mixture layer which includes positive electrode active material particles and a binder. A curve representing a correlation between a distance from a current collector in the thickness direction of the positive electrode material mixture layer and an amount of the binder has a first maximum point, a minimum point, and a second maximum point. The minimum point corresponds to a position in a center area of the positive electrode material mixture layer in a thickness direction thereof, and the first and second maximum points correspond to a position nearer the current collector and a position further away from the current collector than the position corresponding to the minimum point, respectively. A ratio W1/W2 of an amount W1 at the first maximum point to an amount W2 at the minimum point of the binder per 100 parts by weight of the positive electrode active material particles is greater than 2.
