ABSTRACT:
A binder for a lithium ion secondary battery characterized by comprising a polymer containing structural units derived from 1,3-butadiene, said polymer having a 1,2-vinyl structure content in the range of 2% to 25% by mole. A lithium ion secondary battery provided with an electrode made using this binder exhibits improved characteristics at repetition of charge-discharge cycle and improved storage stability.
