SINGLE-LAYER LITHIUM ION BATTERY SEPARATOR |
摘要 |
The present invention relates to a microporous polymeric battery separator comprised of a single layer of enmeshed microfibers and nanofibers. Such a separator accords the ability to attune the porosity and pore size to any desired level through a single nonwoven fabric. As a result, the inventive separator permits a high strength material with low porosity and low pore size to levels unattained. The combination of polymeric nanofibers within a polymeric microfiber matrix and/or onto such a substrate through high shear processing provides such benefits, as well. The separator, a battery including such a separator, the method of manufacturing such a separator, and the method of utilizing such a separator within a battery device, are all encompassed within this invention. |
