SLURRY FOR FORMING INSULATING LAYER, SEPARATOR FOR ELECTROCHEMICAL DEVICE, METHOD FOR PRODUCING THE SAME, AND ELECTROCHEMICAL DEVICE

摘要

Disclosed is a slurry for forming insulating layers, which contains heat-resistant insulating fine particles, a thickening agent and a dispersion medium. The insulating fine particles are dispersed in the dispersion medium, and the ratio of particles having a particle diameter of not more than 1 µm is not less than 30% by volume and the ratio of particles having a particle diameter of not less than 3 µm is not more than 10% by volume in the particles contained in the insulating fine particles. The slurry for forming insulating layers has a viscosity of 5-500 mPa s. An electrochemical device comprising a separator for electrochemical devices which is produced by using the slurry for forming insulating layers is also disclosed.
