Abstract
A negative electrode for non-aqueous electrolyte secondary battery provides a means for improving output characteristics at a high rate. The negative electrode has a negative electrode active material layer having a thickness of 150 to 1500 μm formed on a surface of a current collector. In addition, the negative electrode active material layer includes coated negative electrode active material particles in which at least a part of a surface of a negative electrode active material is coated with a coating agent containing a coating resin and a conductive aid. Furthermore, a porosity of the negative electrode active material layer is 39.0% to 60.0% and a density of the negative electrode active material layer is 0.60 to 1.20 g/cm3.
