A binder composition for secondary batteries having excellent stability over time is produced. A method for producing a binder composition for secondary batteries containing at least a polymer and a dispersion medium, which comprises a metal particulate removal step wherein metal particulates contained in a polymer dispersion containing a polymer and a dispersion medium are removed. A binder composition for secondary batteries, which is obtained by the above-mentioned production method and has a metal particulate content of not more than 10 ppm, said metal particulate content is composed of particles formed from a transition metal component and having a particle diameter of not less than 20 μm. A slurry for secondary battery electrodes, which contains the binder composition for secondary batteries and an electrode active material. A secondary battery electrode wherein an electrode active material layer containing the binder composition for secondary batteries and a positive electrode active material or a negative electrode active material is adhered to a collector. A secondary battery comprising the secondary battery electrode. |
