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.
