Abstract

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 various compositions disclosed include battery electrode plate grids designed to produce a concentration of one or more metal ions in the lead acid battery electrolyte. The disclosure also describes resin coated battery components or battery components coated with a metal oxide layer in which the coatings produce a concentration of one or more metal ions in the lead acid battery electrolyte.

Claims

1. A lead acid battery that comprises a negative electrode, a positive electrode, a separator between the negative and positive electrodes, and an electrolyte in contact with the negative and positive electrodes, wherein an electrode comprises an electrode grid metal alloy with a means for shifting the voltage at which hydrogen is produced at the negative electrode by between about 10 mV and about 120 mV.

2. A lead acid battery comprising the following components:

a case, a negative electrode, a positive electrode, a separator, an electrolyte, and a coating of metal or metal oxide coating a surface of at least one battery component wherein the surface is a surface that contacts the electrolyte within the battery.

3. A lead acid battery comprising the following components:

a case, a negative electrode, a positive electrode, a separator, electrolyte in contact with the components, and a resin containing particles of a metal or metal compound coating a surface of at least one battery component wherein the surface is a surface that contacts the electrolyte within the battery.
