    摘要： Provided is a slurry composition for a non-aqueous secondary battery functional layer that is capable of forming a functional layer that can inhibit heat generation in the event of an internal short circuit of a non-aqueous secondary battery and can also reduce internal resistance of the non-aqueous secondary battery. The slurry composition contains functional particles, a water-insoluble polymer, a water-soluble polymer, and water. The functional particles include foaming agent particles. The content of the water-insoluble polymer is not less than 0.01 parts by mass and not more than 20 parts by mass per 100 parts by mass of the functional particles, and the content of the water-soluble polymer is not less than 1 part by mass and not more than 10 parts by mass per 100 parts by mass of the functional particles. A value (F sup ) calculated by a specific formula (1) is 10 mass% or less.

    摘要： It is an object of the present disclosure to provide an electrode for lithium ion secondary battery-use that can efficiently prevent a temperature increase by reducing current through an increase in the battery internal resistance during abnormal overheating. The electrode for lithium ion secondary battery-use of the present disclosure comprises a binder composition containing particles formed by a second component being located substantially on a portion of the outside of particles comprising a first component. The initial adhesive force of the binder composition is at least 1. The storage elastic modulus of the binder composition at 150°C is no greater than 1,000 Pa.

    摘要： Provided is electrically conductive ink that shows favorable flowability and that can also suppress deformation, such as flattening, upon application of surface pressure.
    The electrically conductive ink is applied onto a substrate 21 of a separator 11 that constitutes a cell 13 of a fuel cell stack by way of screen printing so as to form ribs 22 on the substrate 21, wherein the electrically conductive ink has viscoelasticity, as measured by a rotary rheometer, that exhibits a loss tangent of 1 with a strain of 10 to 100%.
