Conductive composition, current collector with base layer for electric storage device, electrode for electric storage device, and electric storage device
The present invention addresses the problem of providing an electrically conductive composition which can be used for producing an electric storage device such as a non-aqueous electrolyte secondary battery (e.g., a lithium ion secondary battery) having excellent electric conductivity during an ordinary operation and therefore having excellent battery output properties and the like and also having a function of increasing internal resistance when the internal temperature of the battery is increased, and which enables the production of an electric storage device such as a non-aqueous electrolyte secondary battery having excellent electric conductivity and safety-related functions. The problem can be solved by an electrically conductive composition comprising an electrically conductive carbon material (A), a water-soluble resin (B), water-dispersible resin microparticles (C), an aqueous liquid medium (D), and optionally a water-soluble polyvalent metal compound (E), said composition being characterized in that the water-dispersible resin microparticles contain at least olefin resin microparticles.
