titleOfInvention | Method for producing binder for non-aqueous electrolyte secondary battery, electrode composition for non-aqueous electrolyte secondary battery, electrode for non-aqueous electrolyte secondary battery, binder for non-aqueous electrolyte secondary battery and non-aqueous electrolyte secondary battery |
abstract | PROBLEM TO BE SOLVED: To provide a binder for a non-aqueous electrolyte secondary battery capable of obtaining a battery having excellent performance even when an electrode active material containing silicon is used. A non-aqueous electrolyte secondary battery binder containing carboxymethyl cellulose and / or a salt thereof and styrene-butadiene rubber, which satisfies the following conditions (A) and (B). Binder for electrolyte secondary batteries. Condition (A): The degree of carboxymethyl substitution per glucose unit of carboxymethyl cellulose and / or a salt thereof satisfies 0.5 to 1.5. Condition (B): Viscosity VCMC (30 rpm, 23 ° C.) when an aqueous dispersion having a solid content of carboxymethyl cellulose and / or a salt thereof of 2% (w / v) was used, and a solid content of styrene-butadiene rubber of 48% (w / v) (30 rpm, 23 ° C.). The viscosity ratio Vr = V CMC / V SBR to the viscosity V SBR (30 rpm, 23 ° C.) when the aqueous dispersion of w / v) is used satisfies Vr <50. [Selection diagram] None |
