Battery knowledge · Electrolytes and separators
Ceramic-coated separator
A polyolefin separator coated with a thin layer of alumina or boehmite particles. The ceramic raises the temperature at which the film shrinks, so the electrodes stay apart longer in a thermal event.
Example
Electrolytes and separators: an example situation
Greater liquid uptake may improve wetting while changing mechanical behavior. Several properties define separator performance.
Read Ceramic-coated separator alongside Separator in this context. A porous, electronically insulating film between the electrodes. Electrons cannot cross it; ions move through the electrolyte in its pores.
Use in Lemonergy
Connect transport with electronic isolation.
This is a reference concept. No executable Lemonergy block has been verified for this term.
