Nonaqueous electrolyte secondary battery |
| abstract |
A positive electrode for a nonaqueous electrolyte secondary battery according to the present invention includes particles A of a lamellar type lithium transition metal oxide and particles B of a spinel type lithium transition metal oxide, as a positive active material, at a ratio within the range of A:B=20:80 to 80:20 (weight ratio), in which a particle size distribution of the positive active material has a peak based on the particles A and a peak based on the particles B within the range of 1 to 50 μm. In the integrated distribution curve of the particle diameter, a particle diameter A(D50) at a degree of accumulation of the particles A of 50% and a particle diameter B(D50) at a degree of accumulation of the particles B of 50% satisfy the following expression (1), and a particle diameter A(D95) at a degree of accumulation of the particles A of 95% and a particle diameter B(D5) at a degree of accumulation of the particles B of 5% satisfy the following expression (2):n n B ( D 50)− A ( D 50)≧5 μm Expression (1)n n B ( D 5)> A ( D 95) Expression (2). |
