Abstract
Methods of modifying fibers, such as glass fibers, are disclosed. The modified fibers can be used, for example, in a lead acid battery.
Claims34
A method, comprising:
- applying pressure at more than one angle to a plurality of fibers to form a plurality of modified fibers;
- and
- after applying pressure, incorporating at least some of the fibers into a battery electrode paste,
- wherein the plurality of fibers has an average length of greater than 1.5 millimeters before applying pressure and the plurality of fibers has an average length of less than 1.5 millimeters after applying pressure, and pressure is sequentially applied at more than one angle.
1 more element
A method, comprising:
- applying pressure to the plurality of fibers;
- and
- after applying pressure, incorporating at least some of the plurality of fibers into a battery electrode paste,
- wherein the plurality of fibers has a first average length before applying pressure and a second average length after applying pressure, the first average length being at least 15 times greater than the second average length, and pressure is sequentially applied at more than one angle.
1 more element
A method, comprising:
- applying a first pressure to the plurality of fibers;
- removing the first pressure from the plurality of fibers;
- rotating the plurality of fibers;
- applying a second pressure to the plurality of fibers;
- and
- after applying the second pressure, incorporating at least some of the plurality of fibers into a battery electrode paste,
- wherein the plurality of fibers has a first average length before applying the first pressure and a second average length after applying the second pressure, the first average length being greater than the second average length.
