Title:
BINDER COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODES, SLURRY COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODES, ELECTRODE FOR NONAQUEOUS SECONDARY BATTERIES, AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2017/056466
Kind Code:
A1
Abstract:
This binder composition for nonaqueous secondary battery electrodes contains a particulate polymer having a core-shell structure. With respect to the particulate polymer, a core part contains a first polymer that contains an aliphatic conjugated diene monomer unit and an aromatic vinyl monomer unit, and a shell part contains a second polymer that is different from the first polymer and contains 40% by mass or more of a (meth)acrylate monomer unit. In addition, the swelling degree of the particulate polymer in an electrolyte solution is 2.5 times or less.
