Abstract:
Disclosed are battery separators comprising glass fibers and having a basis weight (gsm), a specific surface area (m 2 /g), a density (gsm/mm) and a mean pore size (μm), which satisfy the equation disclosed herein, provided that: the specific surface area is less than 1.5 m 2 /g, or the density is greater than 180 gsm/mm. Also disclosed are batteries comprising the battery separators, and processes for making the separators.

Claim (Index 20):
The battery separator of  claim 2 , wherein the specific surface area is less than 1.50 m 2 /g, wherein the fibers comprise about 5% to about 50% fibers having an average diameter less than or equal to 1.0 \u03bcm, wherein the mean pore size is less than 6 \u03bcm, wherein the density is about 180 gsm/mm to about 400 gsm/mm. wherein the basis weight is between 150 gsm and 1000 gsm, wherein the battery separator has a percent recovery, when compressed from 10 kPa to 100 kPa and recovered to 10 kPa, of greater than 84% when measured according to Battery Council International Battery Technical Manual BCIS-03 (Rev. September 09) method number 1, and wherein the percent recovery is equal to (T rec /T comp )*100%, where T comp  is the thickness of the battery separator at 20 kPa during compression and wherein T rec  is the thickness at 20 kPa during recovery.
