Abstract

Not only are advancements being made in planar lead-acid battery design, but the cost advantages are significant because of the low materials cost of the sealed lead-acid battery. In the authors´ opinion, the planar approach makes more sense in the rectangular world. Cylinder batteries lose 10 to 25% of their energy and volumetric densities when assembled into a rectangular case. Not only does this process cause loss of efficiency, but it adds significant additional cost to the battery pack. Planar batteries offer comparable efficiencies when considering the space and weight of the entire battery pack, not the individual cells. However, these accomplishments are delivered at only a fraction of the cost
