Abstract: Provided is a heat-sensitive layer for a lithium ion secondary battery that can efficiently block rising temperature during abnormal heating by increasing battery internal resistance and thereby reducing current. The heat-sensitive layer for a lithium ion secondary battery is formed from a heat-sensitive layer composition containing particles in each of which a second component is substantially partially disposed at the outside of a particle formed from a first component. The heat-sensitive layer composition has a storage modulus at 60° C. of 10 kPa or more and a storage modulus at 150° C. of 1 kPa or less.

Abstract: A slurry composition for composite particles for a positive electrode includes a positive electrode active material, a conductive material, a water soluble resin including a monomeric unit containing an acidic functional group, and a granular binder resin. The moisture content is at most 25% by mass, and the viscosity at a shear velocity of 10 s−1 is at most 2000 mPa·s. A method for producing composite particles for a positive electrode of an electrochemical element includes kneading a mixture including a positive electrode active material, a conductive material, and a water soluble resin including a monomeric unit containing an acidic functional group, preparing a slurry composition with a moisture content of at most 25% by mass and a viscosity at a shear velocity of 10 s−1 of at most 2000 mPa·s by adding a granular binder resin and water to the kneaded mixture, and spray drying the slurry composition.
