Abstract

This electrode for a lithium ion secondary battery is provided with: an electrode film containing a conductive auxiliary a binder and an active material; and an electrode foil on the surface of which the electrode film is formed. The conductive auxiliary is carbon nanofibers and 0.1 3.0 mass% of the carbon nanofibers is included relative to 100 mass% of the electrode film. When the binder uses an organic solvent as a solvent 1.0 8.0 mass% of the binder from which the organic solvent has been removed is included relative to 100 mass% of the electrode film. The active material constitutes the remaining percentage. The active material comprises a mixed powder of rough powder having an average particle diameter of 1 20µm and fine powder having an average particle diameter 1/3 1/10 of the average particle diameter of the rough powder. The void fraction of the electrode film is 10 30%.
