摘要:
A positive electrode for non-aqueous electrolyte secondary battery that results in improved output characteristics at a high rate has a positive electrode active material layer having a thickness of 150 to 1500 μm formed on a surface of a current collector. In addition, the positive electrode active material layer includes coated positive electrode active material particles in which at least a part of a surface of a positive electrode active material is coated with a coating agent containing a coating resin and a conductive aid. Furthermore, a porosity of the positive electrode active material layer is 35.0% to 50.0% and a density of the positive electrode active material layer is 2.10 to 3.00 g/cm3.
