Abstract
Abstract A lead acid storage battery has a cell composed of a positive plate comprising a positive active material layer and a positive current collector plate, a negative plate comprising a negative active material layer and a negative current collector plate, a separator and a frame-shaped gasket. In the cell, the positive plate and the negative plate are laminated with the gasket put between them. The gasket is in contact with peripheral edges of the positive current collector plate and the negative current collector plate. The positive active material layer and the negative active material layer are located in a cell space surrounded by both of the plates and the gasket with the separator put between them.
