COMPOSITE PARTICLES FOR NEGATIVE ELECTRODES OF SECONDARY BATTERIES, USE OF SAME, METHOD FOR PRODUCING SAME, AND BINDER COMPOSITION

摘要

A secondary battery negative electrode composite particle including a negative electrode active material and a particulate polymer, wherein the particulate polymer include 10% by weight to 60% by weight of a (meth)acrylonitrile monomer unit and 35% by weight to 85% by weight of an aliphatic conjugated diene monomer unit; and a residual amount of an organic compound having an unsaturated bond and a boiling point of 150°C to 300°C is 500 ppm or less as a ratio relative to an amount of the particulate polymer.
