[0065] The formulations of the formulation ratios shown in Table 1 were melt-kneaded using a 5-liter intensive mixer of Nippon Roll MFG Co., Ltd. At this time, the discharge temperature was set at 190°C. Then, using the roll diameter of Japan Roll Manufacturing Co., Ltd., the roll diameter is 200mm, the roll width is 700mm reverse L word four calenders, and the film that obtains thickness is 300 μm (roll temperature according to the first roll / second roll / third roll / The sequence of the fourth roll is 205°C / 205°C / 185°C / 175°C, the drawing speed is 5 m / min). For the obtained film, the volume resistivity ρ and the tensile elongation E were determined, and tests for bending resistance and flexibility were performed according to the following methods. The results are shown in Table 1.

Abstract

Provided is a resin composition for an electroconductive resin film offering excellent electroconductivity, tensile elongation, bending resistance, and flexibility, and suitable for an electrode in a redox flow cell or the like or for covering and protecting the same. A resin composition comprising (A) 100 parts by mass of a thermoplastic resin, (B) 1-60 parts by mass of carbon nanotubes, and (C) 1-100 parts by mass of at least one type selected from the group consisting of acetylene black and graphite.

Description

technical field [0001] The present invention relates to a resin composition used for a conductive resin film, and more specifically, to a resin composition used for a conductive resin film excellent in tensile elongation, bending resistance, or flexibility. Background technique [0002] In recent years, so-called renewable energy such as solar power generation, wind power generation, and wave power generation has attracted attention as a new energy source that can replace fossil fuels such as petroleum or atomic power. However, since these renewable energies are strongly affected by weather and the like, the output is extremely unstable. Therefore, in order to connect a large amount of these energies to the power grid, for example, it is necessary to install a large-capacity storage battery in parallel to stabilize output fluctuations and the like. [0003] One of large-capacity storage batteries is a redox flow cell. A redox flow battery is a battery that separates two ki...
