Abstract

See full text

A nonaqueous electrolyte secondary battery includes a positive electrode. The positive electrode includes a positive electrode active material layer. The positive electrode active material layer includes a first layer and a second layer. The first layer includes a first particle group. The second layer includes a mixture of a second particle group and a third particle group. The first particle group consists of a plurality of first positive electrode active material particles. The second particle group consists of a plurality of second positive electrode active material particles. The third particle group consists of a plurality of third positive electrode active material particles. Each of the first positive electrode active material particles and the third positive electrode active material particles independently includes 1 to 10 single-particles. Each of the second positive electrode active material particles includes secondary particles obtained by aggregation of 50 or more primary particles.
