Abstract
A method is provided for manufacturing an electrode that has a porous inorganic layer on the surface of an active material layer and is suitable for constructing a nonaqueous secondary battery with excellent input-output performance. In this manufacturing method, an electrode perform, which has an active material layer () consisting primarily of active material particles () and supported on a collector (), is prepared. The water concentration of at least the surface () of the active material layer () is adjusted to 100 ppm to 500 ppm. A slurry (S) containing inorganic particles (), a binder and an organic solvent is coated on the surface () of the active material layer with the water concentration thus adjusted, to form a porous inorganic layer.
