Abstract

A positive electrode for non-aqueous electrolyte secondary battery suppresses a decrease in discharge capacity under a high output condition while minimizing an increase in battery temperature in an overcharged state of the battery. The positive electrode includes: a positive electrode current collector; and a positive electrode active material layer that is formed on a surface of the positive electrode current collector, contains a positive electrode active material and a conductive aid, and has a BET specific surface area of from 1 to 3 m/g, in which the conductive aid contains a first conductive aid and a second conductive aid having a larger average particle diameter than the first conductive aid. The content of the first conductive aid is greater than the content of the second conductive aid in the positive electrode active material layer.
