  • Patent number: 10693193
    Abstract: The present disclosure is directed to bi-polar plates for use in lead-acid batteries, and methods of making the same. The bi-polar plates of the present disclosure comprise first and second conductive plates of lead joined by a plurality of connections through a plastic substrate. The connections may be formed by welding or in the process of casting the conductive plates, resulting in connections that are chemically homogenous with the conductive plates themselves. In addition, the welding and casting processes of the present disclosure offer significant time savings in the production of bi-polar plates.

  • Publication number: 20200076027
    Abstract: A bipolar plate includes a first conductive plate and a second conductive plate. The bipolar plate further includes a substrate between the first and second conductive plates. The bipolar plate further includes a plurality of cooling ducts extending from the first conductive plate, through the substrate, and to the second conductive plate. The cooling ducts are configured to permit the flow of a cooling liquid. The bipolar plate may be used in the assembly of a battery, such as a lead-acid battery or other suitable battery.

  • Patent number: 9728772
    Abstract: Positive active material pastes for flooded deep discharge lead-acid batteries, methods of making the same and lead-acid batteries including the same are provided. The positive active material paste includes lead oxide, a sulfate additive, and an aqueous acid. The positive active material paste contains from about 0.1 to about 1.0 wt % of the sulfate additive. Batteries using such positive active material pastes exhibit greatly improved performance over batteries with conventional positive active material pastes.
