| titleOfInvention | Resilient battery separator |
| abstract | The present invention provides a battery separator comprising a nonwoven web of first and second fibers having a mean diameter of about 15 µm or less, wherein the first fibers comprise at least about 60 wt.% of a first polyolefin having a first melting temperature and no more than about 40 wt.% of a second polyolefin having a second melting temperature which is lower than the first melting temperature, the second fibers comprise a third polyolefin having a third melting temperature which is higher than the second melting temperature, the nonwoven web has two sides, one of which sides has been contacted with a heated surface such that the nonwoven web has been subjected to a temperature higher than the second melting temperature and lower than the first and third melting temperatures so as to render the contacted side more smooth than the other side, the battery separator is spontaneously wettable by an electrolyte, the battery separator has a thickness of at least about 50 µm, and the battery separator has a percent rebound thickness of at least about 92% after the application of pressure up to 80 kPa. The present inventive battery separator preferably comprises two such nonwoven webs mated to each other nonsmooth side-to-nonsmooth side. The present invention also provides a method of preparing such a battery separator, as well as a battery incorporating such a battery separator. |
