20090269489 | SEPARATOR PROVIDED WITH ASYMMETRICAL PORE STRUCTURES FOR AN ELECTROCHEMICAL CELL - A separator for an electrochemical cell, comprising (A) a flexible perforate support, and (B) a porous ceramic material which fills the perforations in the support and is suitable for receiving an ion-conducting electrolyte, wherein the porous ceramic material comprises a first porous layer which is characterized by an average pore size and also at least one second porous layer for contacting with an electrode, the second porous layer having an average pore size which is smaller than the average pore size of the first porous layer. | 10-29-2009 |
20090311418 | LITHIUM BATTERY SEPARATOR HAVING A SHUTDOWN FUNCTION - Electrical separators for batteries, especially lithium batteries, having a shutdown mechanism. A process for their production. An electrical separator is used in batteries and other systems in which electrodes have to be separated from each other while maintaining ion conductivity. Safety is very important in lithium batteries, since in contrast to other types of battery (Pb, NiCd, NiMeH) the solvent for the electrolyte is not water but a combustible solvent. A separator for lithium cells must possess a shutdown mechanism while not being able to melt down. This is achieved by an electrical separator having a shutdown layer which comprises particles which melt at a desired temperature, close the pores of the separator, and so stop ion flow. Since the separator also comprises a porous inorganic (ceramic) layer on a carrier, the cells cannot melt down as a result of a completely melted separator. | 12-17-2009 |
