[Problem] To provide a means which is capable of improving the long-term cycle durability of a large-sized nonaqueous electrolyte secondary battery that can be used in applications such as driving of an electric vehicle. [Solution] A negative electrode for nonaqueous electrolyte secondary batteries, which comprises a collector and a negative electrode active material layer that is arranged on the surface of the collector and contains a negative electrode active material. The negative electrode active material contains, as a main component, an artificial graphite, a coated natural graphite or a natural graphite; and if X (% by mass) is the content of the artificial graphite contained in the negative electrode active material, Y (% by mass) is the content of the coated natural graphite contained in the negative electrode active material, and Z (% by mass) is the content of the natural graphite contained in the negative electrode active material (provided that X + Y + Z = 100% by mass), Y ≥ Z and Y ≥ X are satisfied (excluding the case where (X, Y, Z) = (0, 1, 0)). |
