Japanese Patent JPWO2022138085
Kind Code:
A1
Abstract:
A binder composition for a non-aqueous secondary battery negative electrode contains a particulate binder and an aromatic ring-fused nitrogen-containing five-membered ring compound or an aromatic-substituted nitrogen-containing five-membered ring compound. The particulate binder includes at least an aromatic vinyl monomer unit and an aliphatic conjugated diene monomer unit. The aromatic ring-fused nitrogen-containing five-membered ring compound or the aromatic-substituted nitrogen-containing five-membered ring compound is an anionic aromatic compound having 4n+2 ring π electrons (n is an integer of 1 or more). The content of the anionic aromatic compound is more than 1 part by mass and less than 10 parts by mass per 100 parts by mass of the particulate binder.
