Title:
BINDER COMPOSITION FOR LITHIUM-ION SECONDARY CELL POSITIVE ELECTRODE, SLURRY COMPOSITION FOR LITHIUM-ION SECONDARY CELL POSITIVE ELECTRODE, LITHIUM-ION SECONDARY CELL POSITIVE ELECTRODE, AND LITHIUM-ION SECONDARY CELL
Document Type and Number:
WIPO Patent Application WO/2016/157842
Kind Code:
A1
Abstract:
Provided is a binder composition for a lithium-ion secondary cell positive electrode with which swelling of the positive electrode can be minimized. This binder composition for a lithium-ion secondary cell positive electrode contains a solvent and a copolymer including a nitrile group-containing monomer unit and a conjugated diene monomer unit. The electrolyte swelling degree of the copolymer is 200-700% by mass, and the storage elasticity of a binder film obtained by forming the binder composition into a film is 1×104Pa to 1×109Pa.
