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

The present disclosure generally relates to filter media including glass fibers. The fiber characteristics (e.g., composition, dimensions) are selected to impart the desired solubility, filtration and mechanical properties so that the filter media may be used in the desired application.

Filter media including glass fibers

Disclosed are glass compositions, glass fiber compositions, glass fiber battery separators, glass fiber filter media, battery additives and active materials formed with glass compositions disclosed, glass fiber radiation shields, and glass fiber paper compositions. Certain embodiments include, among other components, bismuth oxide. Certain embodiments include about 0.5-30% bismuth oxide of the composition by weight and silica oxide at about 54-70% of the composition by weight. Embodiments may also include other components. For example, zinc oxide can make up about 0.01-3% of the composition by weight.

Batteries containing bismuth glass compositions

Glass compositions

Disclosed are glass compositions and glass fibers formed from certain embodiments of the disclosed glass compositions. Certain embodiments of the glass compositions include, among other components, bismuth oxide. Certain embodiments of the glass composition include about 0.5&#x2013;30% bismuth oxide of the composition by weight and silica oxide at about 54&#x2013;70% of the composition by weight. Embodiments of the glass compositions may also include other components. For example, zinc oxide can make up about 0.01&#x2013;5% of the composition by weight.
