Title:
絶縁層形成用スラリー、電気化学素子用セパレータの製造方法、及び電気化学素子
Document Type and Number:
Japanese Patent JP5753657
Kind Code:
B2
Abstract:
A slurry for forming an insulating layer of the present invention includes heat-resistant insulating fine particles, a thickening agent, and a dispersion medium. The insulating fine particles are dispersed in the dispersion medium. The slurry for forming an insulating layer has a viscosity of 5 to 500 mPa·s. The proportion of particles with a particle size of 1 μm or less in the insulating fine particles is 30 vol % or more and the proportion of particles with a particles size of 3 μm or more in the insulating fine particles is 10 vol % or less. An electrochemical device of the present invention includes a separator for an electrochemical device of the present invention that is produced using the slurry for forming an electrochemical device of the present invention.
