Abstract
Embodiments of the invention provide an electrically conductive resin composition which enables the formation of a film that has high electrical conductivity and excellent tensile elongation, bending resistance and flexibility, and is suitable for an electrode member for a storage battery. At least one embodiment provides a resin composition including (A) 100 parts by mass of a thermoplastic resin, (B) 1 to 60 parts by mass of carbon nanotubes, and (C) 1 to 60 parts by mass of acethylene black, wherein the thermoplastic resin (A) includes (A1) 30 to 80% by mass of a chlorinated polyethylene having a chlorine content of 20 to 45% by mass and (A2) 70 to 20% by mass of a polyethylene that is different from the component (A1). According to another embodiment, the thermoplastic resin (A) is (A3) a polyethylene that satisfies the following properties (p) and (q): (p) the peak top melting point on the highest temperature side in a DSC melting curve is 120° C. or higher; and (q) the ratio of melting enthalpy in a temperature range of 110° C. or lower relative to the total melting enthalpy in the DSC melting curve is 50 to 80%.
