Title:
HIGH DIELECTRIC CONSTANT NANO-COMPOSITE COATING SEPARATOR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/201757
Kind Code:
A1
Abstract:
The present invention provides a high dielectric constant nano-composite coating separator having a high ionic conductivity and excellent battery performance and manufacturing method thereof. The nano-composite coating prepared by inorganic-organic polymer composite particles formed by compounding 50-90 parts by weight of gel polymer and 10-50 parts by weight of nano inorganic ceramic particles, has a dielectric constant significantly higher than that of the prior art and enhanced safety. The present invention utilizes a cooperative effect of the characteristic of the high dielectric constant inorganic nano-particles and the polymer of low molecular weight to obtain the inorganic-organic polymer composite particles for preparing the nano-composite coating separator having the characteristics of high-efficiency absorption and gelation of an electrolyte and excellent battery performance. The processes of synthesis and slurry preparation adopted by the present invention produce no other byproducts, and all solid components function effectively in the battery, thus being highly efficient, low-cost, and environmentally friendly.
