Title: COMPOSITE PARTICLES FOR NEGATIVE ELECTRODES OF SECONDARY BATTERIES, USE OF SAME, METHOD FOR PRODUCING SAME, AND BINDER COMPOSITION
Abstract:
Composite particles for negative electrodes of secondary batteries, which contain a negative electrode active material and a particulate polymer. The particulate polymer contains 10-60% by weight of a (meth)acrylonitrile monomer unit and 35-85% by weight of an aliphatic conjugated diene monomer unit. The amount of a residual organic compound that contains an unsaturated bond and has a boiling point of 150-300°C is 500 ppm or less relative to the amount of the particulate polymer.
