    Abstract: Composite particles for a positive electrode of an electrochemical element include a conductive material, a Ni containing positive electrode active material, a water soluble resin including a monomeric unit containing an acidic functional group, and a granular binder resin. The content of the water soluble resin is 1 to 10 parts by mass per 100 parts by mass of the Ni containing positive electrode active material. An electrochemical element includes a collector and a positive electrode active material layer obtained by formation with the composite particles. Furthermore, a method for producing the composite particles includes drying and granulating an aqueous slurry composition including the above components in order to obtain the composite particles. The content in the slurry composition of the water soluble resin is 1 to 10 parts by mass per 100 parts by mass of the Ni containing positive electrode active material.

    Abstract: Provided is a binder composition for a solid electrolyte battery having excellent processability in solid electrolyte battery production and with which a solid electrolyte battery having excellent battery performance can be obtained. The binder composition for a solid electrolyte battery contains a particulate polymer having a core-shell structure and an organic solvent. A mass ratio of content of a polymer forming a core portion of the particulate polymer relative to content of a polymer forming a shell portion of the particulate polymer (i.e., a ratio of “polymer forming core portion/polymer forming shell portion”) is 1/0.3 to 1/5.

    Abstract: 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.
