<P>PROBLEM TO BE SOLVED: To provide a water base slurry for forming a negative electrode coating film of a nonaqueous secondary battery, having safe handling, excellent adhesion of a synthetic carbon material such as graphitization-resistant carbon, mesophase-carbon micro beads or the like, or a scaly or scale-like graphite material to a collector, little lowering of discharge capacity, and excellent durability with respect to a charge/discharge cycle. <P>SOLUTION: This slurry for forming the negative electrode coating film of the nonaqueous secondary battery is basically composed of a solid content comprising a carbonaceous active material and a binder and a water medium. The binder is composed of a water-dispersed emulsion resin and a water-soluble high polymer, and the water-dispersed emulsion resin comprises a synthetic resin having a glass transition temperature of 0°C or higher and an average particle diameter of 0.15-0.45 μm. <P>COPYRIGHT: (C)2004,JPO |
