BINDER COMPOSITION FOR SECONDARY BATTERY NEGATIVE ELECTRODE, SLURRY COMPOSITION FOR SECONDARY BATTERY NEGATIVE ELECTRODE, NEGATIVE ELECTRODE FOR SECONDARY BATTERY, SECONDARY BATTERY, AND MANUFACTURING METHOD OF BINDER COMPOSITION FOR SECONDARY BATTERY NEGATIVE ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a productive binder composition for a secondary battery negative electrode of good battery cycle properties, a slurry composition for the secondary battery negative electrode using the binder composition, a negative electrode for a secondary battery, the secondary battery, and a manufacturing method of binder composition for the secondary battery negative electrode.SOLUTION: The binder composition for the secondary battery negative electrode contains a binder comprising 20-60 wt.% of aliphatic conjugated diene monomer units, 1-10 wt.% of ethylene system unsaturated carboxylic acid monomer units, and 30-79 wt.% of the weight of other monomer units capable of copolymerization with these, and 0.5-50 ppm free alkyl mercaptan against 100 pts.wt. of the binder.
