Ceramic Separator for Electrochemcial Cells With Improved Conductivity |
摘要 |
Separator for an electrochemical cell comprising a flexible perforate carrier having a ceramic coating on and in the carrier, the ceramic coating comprising from 75 to 99 parts by mass of oxidic particles selected from particles of ZrO<SUB>2</SUB>, SiO<SUB>2 </SUB>and Al<SUB>2</SUB>O<SUB>3 </SUB>and comprising from 1 to 25 parts by mass of zeolite particles. These separators exhibit distinctly improved ion conductivity after filling with an electrolyte and are useful as separators in lithium ion batteries in particular.
