Abstract
The present invention is to provide a binder composition of a non-aqueous electrolyte secondary battery, which contains a vinylidene fluoride polymer and is capable of further enhancing adhesive strength of the electrode mixture layer to a surface of a current collector. The above objective can be achieved by a binder composition of a non-aqueous electrolyte secondary battery, the binder composition comprising a vinylidene fluoride copolymer for a binder of a non-aqueous electrolyte secondary battery, the vinylidene fluoride copolymer containing: a first constituent unit derived from vinylidene fluoride, and a second constituent unit containing an isocyanate group or having a structure that produces an isocyanate group when heated at 200° C. for 1 hour. This binder composition can be used in a mixture for producing an electrode for a non-aqueous electrolyte secondary battery, an electrode for a non-aqueous electrolyte secondary battery, and a non-aqueous electrolyte secondary battery.
