Beschreibung
Zusammenfassung:This conductive composition contains a conductive carbon material (A), a water-soluble resin binder (B), a water-dispersible resin particle binder (C) and an aqueous liquid medium (D), and is characterized in that, of the total 100wt% of solid content of the conductive carbon material (A), the water-soluble resin binder (B) and the water-dispersible resin particle binder (C), the content of the conductive carbon material (A) is 20-70wt%, and of the total 100 wt% of solid content of the water-soluble resin binder (B) and the water-dispersible resin particle binder (C), the content of the water-soluble resin binder (B) is greater than or equal to 3 wt% and less than 40 wt%. Hereby, it is possible to provide a conductive composition for forming a power storage device with excellent conductivity and adhesion, excellent dispersibility of the conductive carbon material and electrode adhesion, and excellent charge-discharge cycle characteristics.
