Abstract:
The present invention aims at providing slurry for electrodes having advantageous homogeneity and stability, an electrode having advantageous homogeneous thickness and density, and further, a nonaqueous electrolyte secondary battery having small variability in battery properties.In the present invention, slurry for electrodes is produced by using the binder composition used for manufacturing a nonaqueous electrolyte secondary battery wherein polymers for binding active materials are dissolved or dispersed in organic solvent or water, and a total sum of content ratios of monomer and oligomer is 300 ppm or less.
