Disclosed is an electrode for a lithium-ion secondary battery in which a porous membrane containing an oxide particle having a particle size of 5 nm or more to 100 nm or less is layered on an electrode active material layer; a slurry for a porous membrane comprising an oxide particle having a particle size of 5 nm or more to 100 nm or less, a polymer having a glass-transition temperature of 15° C. or less and a solvent; and a lithium-ion secondary battery comprising a positive electrode, a negative electrode and an electrolyte solution in which at least one of the positive electrode and negative electrode is the electrode of the present invention. The purpose is to provide a porous membrane able to contribute to reduction of an attached matter to a roll when being wound up due to improved retention of inorganic filler on the surface part of the porous membrane for a porous protective membrane provided on the surface of an electrode used for a secondary battery and the like. |
