US 9,269,941 B2 · Molten salt battery

Abstract

A molten-salt battery is provided with rectangular plate-like negative electrodes (21) and rectangular plate-like positive electrodes (41) each housed in a bag-shaped separator (31). The negative electrodes (21) and positive electrodes (41) are arranged laterally and alternately in a standing manner. A lower end of a rectangular tab (22) for collecting current is joined to an upper end of each negative electrode (21) close to a side wall (1A) of a container body (1). The upper ends of the tabs (22) are joined to the lower surface of a rectangular plate-like tab lead (23). A lower end of a rectangular tab (42) for collecting current is joined to an upper end of each positive electrode (41) close to a side wall (1B) of the container body (1). The upper ends of the tabs (42) are joined to the lower surface of a rectangular plate-like tab lead (43).
