A metal halogen battery system, said system having the following construction, a store means constructed in the form of a container which includes a generally unitary filter means extending around most of the inside surface of the container and with the filter means being spaced a predetermined distance away from said surface to form spacing between the filter means and the inside surface, said filter means being operative to separate the hydrate formed from the liquid electrolyte, a hydrate former-gas pump means associated with the store means and being operative to intermix halogen gas from the battery cell with aqueous electrolyte from the store means and from the cell, a gas space means being maintained at the top of the store means with the hydrate former-pump means exhausting into the proximity of the gas space, said gas space means being operative to reduce transfer of liquid from the store to the cell, exit conduit means generally adjacent the top of the store means for transmitting fluid containing halogen gas to the cell, and second exit conduit means generally adjacent the bottom of the store means for recirculating filtered electrolyte to the battery system.

This invention is directed toward a seal (25) for fused salt batteries (10) having a current conducting rod (19) partially within said battery and partially outside which includes a layer of compressible material (32) on the body of the current conducting rod leaving exposed the opposite ends thereof and a swaged metal sheath (33) covering and compressing the layer of material to approximately its maximum density. Optionally, a sealing glass (35) having a low coefficient of thermal expansion approximating that of the current conducting rod and the metal sheath can also be employed over the end of the rod and/or a plating (31) of a conductive metal can be provided over the end of the current conducting rod outside of the battery and/or a separate coating (28) of a different material can be deposited on the rod between the rod and the layer of compressible material. A process is also provided for forming the seal.

The connector of this invention comprises a thin, flexible sheet of graphite in which the pores and voids of the graphite are filled with a polymer to render the graphite impervious to the electrolyte of the capacitor.
