Abstract
A manufacturing method of a lithium ion secondary battery includes: forming a first mixture by mixing powder of a first electrode material, which is one of the active material and the conductive material, with powder of trilithium phosphate; forming a second mixture by mixing the first mixture with powder of a second electrode material which is the other one of the active material and the conductive material; forming a wet granulated body by mixing the second mixture with the binder and a solvent; and forming the active material layer by attaching the wet granulated body to the surface of the current collector foil.
