Filter media comprising nanofibers and related components, systems, and methods associated therewith are provided. In some embodiments, a filter media may comprise a first fiber web and a second fiber web designed to impart beneficial properties to the filter media. For instance, in some embodiments, the first fiber web may provide high particulate efficiency and the second fiber web may provide suitable capacity. In some embodiments, the first and second fiber webs may have certain properties (e.g., water contact angle, surface energy) that are similar or substantially the same. The similarities between the first and second fiber webs may serve to enhance the structural stability of the filter media under various conditions (e.g., high temperature, high pressure, steam sterilization) and/or permeability to certain fluids (e.g., water). Filter media, as described herein, may be particularly well-suited for applications that involve liquid filtration.

Stable filter media including nanofibers

Disclosed are battery separators comprising glass fibers and having a basis weight (gsm), a specific surface area (m/g), a density (gsm/mm) and a mean pore size (&#x3bc;m), which satisfy the equation disclosed herein. Also disclosed are batteries comprising the battery separators, and processes for making the separators.

Battery separators with controlled pore structure

Filter media, including those suitable for hydraulic applications, and related components, systems, and methods associated therewith are provided. The filter media described herein may include two or more layers, at least one of the layers having a relatively high percentage of microglass fibers. Additionally, the filter media may be designed such that the ratio of average fiber diameters between two layers is relatively small, which can lead to a relatively low resistance ratio between the layers. In some embodiments, at least one layer of the filter media comprises synthetic polymer fibers. Certain filter media described herein may have desirable properties including high dirt holding capacity and a low resistance to fluid flow. The media may be incorporated into a variety of filter element products including hydraulic filters.

Filter media suitable for hydraulic applications

The disclosure describes compositions and methods for producing a change in the voltage at which hydrogen gas is produced in a lead acid battery. The compositions and methods relate to producing a concentration of one or more metal ions in the lead acid battery electrolyte. The compositions include glass based compositions that are included as part of various battery components, such as the battery separator, pasting paper, additives to battery paste, etc.

Glass compositions with leachable metal oxides and ions

Disclosed are battery separators comprising glass fibers and having a basis weight (gsm), a specific surface area (m/g), a density (gsm/mm) and a mean pore size (&#x3bc;m), which satisfy the equation disclosed herein, provided that: the specific surface area is less than 1.5 m/g, or the density is greater than 180 gsm/mm. Also disclosed are batteries comprising the battery separators, and processes for making the separators.
