The present invention provides a lyocell fiber with increased tendency to fibrillate, requiring a time of less than 80 minutes to obtain a 50 SR value according to ISO 5267-1: 1999 while the reduction of the working capacity [c N/tex*] at the 50 SR value is less than 50%, as well as a method for producing same and products comprising same.

The present invention describes special cellulose compositions that allow a lyocell fiber with a reduced cellulose content to be produced on a stable industrial scale, as well as the lyocell fiber produced from it.

An insulating (nonconductive) microporous polymeric battery separator comprised of a single layer of enmeshed microfibers and nanofibers is provided. Such a separator accords the ability to attune the porosity and pore size to any desired level through a single nonwoven fabric. Through a proper selection of materials as well as production processes, the resultant battery separator exhibits isotropic strengths, low shrinkage, high wettability levels, and pore sizes related directly to layer thickness. The overall production method is highly efficient and yields a combination of polymeric nanofibers within a polymeric microfiber matrix and/or onto such a substrate through high shear processing that is cost effective 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.
