Title:
二次電池電極用バインダー組成物、二次電池電極用スラリー、及び二次電池電極
Document Type and Number:
Japanese Patent JP4992217
Kind Code:
B2
Abstract:

To provide a binder composite for a secondary battery electrode excellent in adhesion to a collector, whereby a secondary battery causing little capacity drop in high speed discharge and having excellent output characteristics can be manufactured.

This binder composite for the secondary battery electrode contains (A) a polymer in which the content of THF gel is not more than 5%, and an organic solvent having (B) N-methyl pyrrolidone as a main component. Its second virial coefficient measured by a static light scattering method is not more than 3×10-5cm3mol/g2, and the radius of rotation of the (A) polymer is 10-500 nm.
