Bipolar lead-acid battery plates

摘要

Electrodes, particularly useful in bipolar plates of lead-acid batteries, include a metal-containing substrate, an electrically conductive material secured to the first side of the substrate, an electrically conductive layer including a polymer secured to the second side of the substrate; and a metallic layer secured to the electrically conductive layer so that the electrically conductive layer is located between the metallic layer and the substrate. Bipolar plates are provided and include an electrically conductive electrode element, a grid spaced apart from the electrode in proximity to the first side of the electrode element, positive active material in contact with the first side or second side of the electrode element and negative active material in contact with the first side or second side of the electrode element which is not in contact with the positive active material.
