Abstract
Fine glass fibers, as well as fiber webs, separators, and pasting papers comprising the fine glass fibers, are generally described. In some embodiments, the fine glass fibers have a relatively high BET specific surface area (e.g., greater than or equal to 1.6 m2/g) while maintaining a relatively low aspect ratio (e.g., less than or equal to 80).
Claims35
A battery separator, comprising:
- a fiber web comprising fine glass fibers;
- wherein the fine glass fibers have an average diameter of less than 1.6 microns, an average aspect ratio of less than or equal to 80, and an average BET specific surface area of greater than or equal to 1.6 m2/g;
- and
- wherein the fiber web has a basis weight of greater than or equal to 20 g/m2 and less than or equal to 600 g/m2.
A pasting paper for use in a battery, comprising:
- a fiber web comprising fine glass fibers;
- wherein the fine glass fibers have an average diameter of less than 1.6 microns, an average aspect ratio of less than or equal to 80 and an average BET specific surface area of greater than or equal to 1.6 m2/g;
- and
- wherein the pasting paper has a thickness of greater than or equal to 0.1 mm and less than or equal to 0.5 mm.
A plurality of glass fibers comprising fine glass fibers having an average diameter of less than 1.6 microns, an average aspect ratio of less than or equal to 80, and an average BET specific surface area of greater than or equal to 1.6 m2/g.
