摘要： A sodium-sulfur battery according to the present invention is provided with a reservoir space 100 that retains and solidifies a high-temperature molten material having flowed out of a cell 4, in order to prevent the high-temperature molten material from leaking out of a casing 1, even when an accident occurs to generate the high-temperature molten material inside the casing. The reservoir space 100 can be formed along a perimeter of the casing 1, or alternatively, can be formed inside the casing 1. The reservoir space 100 includes, for example, a composite member 15 of a rigid member 11, a heat-insulating material 12, and a heat-resisting material 13.

摘要： An outer peripheral surface of a cylindrical cell is coated with a heat insulation material. A heat-resistant material is stacked radially outside the heat insulation material. An electrical insulation material is stacked radially outside the heat-resistant material. The order in which the heat insulation material, the heat-resistant material and the electrical insulation material are stacked one on top of another may be changed. A coating material other than the heat insulation material, the heat-resistant material and the electrical insulation material may be provided.

摘要： An NaS battery module includes a container, a plurality of cells for an NaS battery and sand. The side walls of the container partition the inside and outside of the container in a direction in which the arrangement plane of the cells extends. An upper wall and a lower wall of the container partition the inside and outside of the container in a direction perpendicular to the direction in which the arrangement plane of the cells extends. The lower wall and the side walls are high heat insulating walls whereas the upper wall is a solid low heat insulating wall having a heat insulating property lower than that of the high heat insulating wall. The cells and the sand are housed inside of the container. A variable louver is disposed outside of the upper wall so as to cover the outer surface of the upper wall.
