BINDEMITELL ZUR VERWENDUNG IM ELEKTROLYTEN VON LITHIUM-SEKUNDÄRZELLEN UND DESSEN VERWENDUNG

摘要

Binder for a lithium ion secondary cell electrode contains a polymer having structural units derived from 1,3-butadiene. The content of 1,2-vinyl structures of the polymer in the binder is 2-25 mol%. Independent claims are also included for the following: (1) a binder composition for lithium ion secondary cell electrodes which is a dispersion in which a binder is dispersed in a dispersion medium whose boiling point at normal pressure is 80-350[deg]C; (2) a slurry for lithium ion secondary cell electrodes containing the binder composition and active material; (3) an electrode for a lithium ion secondary cell manufactured using the binder; and (4) a lithium ion secondary cell containing the electrode.
