Abstract
In one or more embodiment described herein, a precursor of an active material of an electrode of a lead-acid battery may be made by a process that includes forming an active material paste and curing the active material paste to form the precursor of the active material of the electrode of the lead-acid battery. The active material paste may be made by combining at least water, an acid, a glass composition having at least 25 wt. % of a single metal oxide, and lead oxide. The metal oxide may be selected from barium oxide, lead oxide, zinc oxide, or antimony oxide.
Claims16
A method for forming the precursor of an active material of an electrode of a lead-acid battery, the method comprising:
- forming an active material paste by a method comprising combining at least water, an acid, a glass composition comprising at least 75 wt. % of lead oxide, and lead oxide, wherein the glass composition is granular, and wherein the lead oxide is granular;
- curing the active material paste to form the precursor of the active material of the electrode of the lead-acid battery.
A precursor of an active material of a lead-acid battery, wherein the precursor is formed by a method comprising:
- forming an active material paste by a method comprising combining at least water, an acid, a glass composition comprising at least 75 wt. % of lead oxide, and lead oxide, wherein the glass composition is granular, and wherein the lead oxide is granular;
- and
- curing the active material paste to form the precursor of the active material of the electrode of the lead-acid battery.
A lead-acid battery, the lead-acid battery comprising:
- an electrolyte solution;
- at least one negative plate;
- and
- at least one positive plate;
- wherein:
- one or both of the at least one negative plate or at least one positive plate comprise an active material formed from a precursor of an active material;
- the precursor of the active material is formed by a process comprising:
- forming an active material paste by a method comprising combining at least water, an acid, a glass composition comprising at least 75 wt. % of lead oxide, and lead oxide, wherein the glass composition is granular, and wherein the lead oxide is granular;
- and
- curing the active material paste to form the precursor of the active material of the electrode of the lead-acid battery.
A method for forming the precursor of an active material of an electrode of a lead-acid battery, the method comprising:
- forming an active material paste by a method comprising combining at least water, an acid, a glass composition comprising at least 25 wt. % of a single metal oxide, and lead oxide, wherein the glass composition is granular, wherein the lead oxide is granular, and wherein the metal oxide is selected from the group consisting of:
- barium oxide;
- lead oxide;
- zinc oxide;
- tin oxide;
- or
- antimony oxide;
- curing the active material paste to form the precursor of the active material of the electrode of the lead-acid battery;
- wherein one or both of:
- the glass composition comprises at least 25 wt. % of zinc oxide;
- or
- the glass composition comprises at least 25 wt. % of antimony oxide.
