SLURRY COMPOSITION FOR NEGATIVE ELECTRODES OF LITHIUM ION SECONDARY BATTERIES, NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERIES, METHOD FOR PRODUCING NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERIES, AND LITHIUM ION SECONDARY BATTERY

摘要

A slurry composition for negative electrodes of lithium ion secondary batteries, which contains a negative electrode active material, a conductive material, a water-soluble polymer and a particulate binder. The amount of the conductive material is 0.1-10 parts by weight per 100 parts by weight of the negative electrode active material. The viscosity of 1% aqueous solution of the water-soluble polymer is 10-3,000 mPa·s. The particulate binder contains a particulate binder (A) that has a surface acid amount of from 0.01 meq/g to 0.10 meq/g (inclusive) and a particulate binder (B) that has a surface acid amount of from 0.15 meq/g to 0.5 meq/g (inclusive).
