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.

The present invention is generally directed to energy storage systems comprising manufactured architectural materials having electrical battery systems embedded therein. The manufactured materials are generally provided as architectural panels, such as panels useful for interior or exterior cladding for buildings, flooring, countertops, or stairs. The panels comprise at least one battery device or battery assembly that is over-formed by and/or bonded with the architectural material. In preferred embodiments, the panels are formed by flowing a viscous architectural material precursor around the battery device or assembly and curing the precursor so as to solidify the architectural material. The panels may be electrically connected in any number of various arrangements, which can be chosen based on the specific application for the energy storage system.
