Abstract
An improvement in lead-acid batteries is disclosed. The improvement is directed toward construction of a lead-acid rechargeable battery in which bipolar positive and negatives plates (biplates) share the same grid or substrate. According to the present invention, such biplates are stacked upon each other, separated by interleaved, highly porous glass mat separators. These substratea positioned between the positive and negative plate areas act as electrical connections attaching the plates to terminals of the battery. The battery case cover is used to provide compressive force on the biplates and separators.
