| 摘要 |
The present invention provides a negative electrode aqueous slurry for a lithium ion secondary battery, a negative electrode active material layer produced by using the same, and a lithium ion secondary battery including the same negative electrode active material layer. The negative electrode aqueous slurry includes: a negative electrode active material including a carbon-based active material, a silicon-based active material, a tin-based active material, or combination of those; and a binder including a copolymer of: acrylic acid or salt of an acrylic acid derivative; and acrylonitrile or an acrylonitrile derivative. |
