Document Type and Number:
Japanese Patent JP7009048
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a conductive composition for forming a power storage device having the function of increasing the internal resistance when the internal temperature of a power storage device rises, which is superior in conductivity during a normal operation.SOLUTION: The above problem is solved by a conductive composition for forming a backing layer of an electrode for a power storage device. The conductive composition comprises a particular amount of: a conductive carbon material (A); water-dispersible resin fine particles (B); a water-soluble resin (C); and an aqueous liquid medium (D). The water-dispersible resin fine particles include at least polyolefin-based resin fine particles. The percentage of the polyolefin-based resin fine particles included in the water-dispersible resin fine particles (B) is 50-100 mass%. The polyolefin-based resin fine particles include at least two kinds of fine particles, i.e. high-density polyolefin-based resin fine particles (B1) having a density of 0.96-1.2 g/cmand having no carbonyl group, and polyolefin-based resin fine particles (B2) having a carbonyl group.SELECTED DRAWING: None
