METHOD FOR PREPARING SLURRY COMPOSITION FOR ELECTRODE OF SECONDARY CELL

摘要

A method for preparing a slurry composition for an electrode of a secondary cell, which comprises kneading an electrode active material and a dispersion in a solvent (SA) of a polymer (A) containing 50 wt % or more of a portion insoluble in the solvent (SA), and then kneading the above-kneaded fluid and a solution of a polymer (B) in a solvent (SB). A slurry composition prepared by the method is reduced in the change of the viscosity thereof due to the elapse of time and exhibits good sticking property, and provides an electrode of a secondary cell having a mixed layer of a flat surface and a uniform thickness through applying the composition on a collector followed by drying.
