Abstract

A conductive composition for electrode is provided that is excellent in conductivity and dispersibility. Further, an electrode for lithium ion secondary battery with lower plate resistance and a lithium ion secondary battery excellent in rate characteristics are provided that use this conductive composition. A conductive composition for electrode, including: carbon nanofiber with a median diameter D50 value by volume from 0.1 to 8 pm; an active material; and a binder enables production of an electrode for lithium ion secondary battery with lower plate resistance and a lithium ion secondary battery excellent in rate characteristics.
