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

摘要

Provided is an aqueous slurry composition for the positive electrode of a lithium ion secondary battery, which can suppress both the generation of pin holes and the occurrence of bulging along the edge portion of a positive electrode active material layer. The slurry composition for the positive electrode of a lithium ion secondary battery includes a positive electrode active material, a conductive material, a viscosity modifier, a particulate binder, a surfactant, and water. The surfactant contains a polyoxyethylenic surfactant (a) and a sulfosuccinic acid ester or its salt (b).
