Title:
BINDER COMPOSITION, MIX FOR MANUFACTURING ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL, ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL, AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL
Document Type and Number:
WIPO Patent Application WO/2019/176163
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a binder composition for a non-aqueous electrolyte secondary cell containing a vinylidene fluoride polymer, the binder composition making it possible to further increase the strength of adhesion of an electrode mix layer with respect to the surface of a collector. The above purpose is achieved by a binder composition for a non-aqueous electrolyte secondary cell, the binder composition containing a vinylidene fluoride copolymer for a binder for a non-aqueous electrolyte secondary cell, the vinylidene fluoride copolymer includiong a first constituent unit derived from vinylidene fluoride and a second constituent unit having an isocyanate group or a structure that generates an isocyanate group when heated for one hour at 200°C. The binder composition can be used in a mix for manufacturing an electrode for a non-aqueous electrolyte secondary cell, an electrode for a non-aqueous electrolyte secondary cell, and a non-aqueous electrolyte secondary cell.
