Title:
BINDER COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY NEGATIVE ELECTRODE, SLURRY COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY NEGATIVE ELECTRODE, NEGATIVE ELECTRODE FOR NON-AQUEOUS SECONDARY BATTERY, AND NON-AQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/074356
Kind Code:
A1
Abstract:
This binder composition for a non-aqueous secondary battery negative electrode comprises a particulate polymer and water. The particulate polymer is composed of a polymer containing: an ethylenically unsaturated carboxylic acid monomer unit, an aromatic vinyl monomer unit, and an alkylene structural unit. A binder film formed using the binder composition for a non-aqueous secondary battery negative electrode demonstrates a maximum displacement, as determined by a microcompression testing machine, of 30 μm or less when the binder film is compressed to a maximum load of 20 mN at a loading rate of 0.2975 mN/s.
