Bipolar battery plate and fabrication thereof

A method for providing a bipolar battery plate, the method comprising:

• treating a first surface of a conductive substrate, the first surface comprising lead or a lead alloy;
• treating a second surface of the conductive substrate opposite the first surface, the second surface comprising lead or a lead alloy;
• depositing a first wet active material paste upon a specified portion of the treated first surface, the first wet active material paste comprising lead;
• depositing a different second wet active material paste upon a specified portion of the treated second surface, the second wet active material paste comprising lead dioxide;
• and
• curing the first wet active material paste and the second wet active material paste contemporaneously to provide a first battery electrode having a first conductivity type upon the first surface and a second battery electrode having an opposite second conductivity type upon the second surface;
• wherein the bipolar battery plate is located in a stack of other respective bipolar battery plates, where respective bipolar battery plates are isolated from each other by a separator having controlled porosity at least during the curing;
• and
• wherein pressure is applied to place a stack of the respective bipolar battery plates in compression at least during the curing.

A method for providing a bipolar battery plate, comprising:

• forming a conductive substrate;
• forming an ohmic contact layer upon a first surface of the substrate;
• forming an adhesion layer upon the ohmic contact layer, the adhesion layer comprising lead or a lead alloy;
• depositing a first wet active material paste upon a specified portion of the first surface, the first wet active material comprising lead or a lead oxide, the first wet active material paste including a patterned surface or profile;
• and
• curing the first wet active material paste including using multiple phases of curing defining different environmental conditions including varying at least one of temperature or humidity during a respective phase to form a corrosion layer, with at least two phases including elevated temperature versus ambient, the curing to provide an electrode having first conductivity type for the bipolar battery plate;
• wherein the bipolar battery plate is located in a stack of other respective bipolar battery plates, where respective bipolar battery plates are isolated from each other by a separator having controlled porosity at least during the curing.
