Treatment of electrochemical cell components with lithium tetrachloroaluminate (LiAlCl/sub 4/) to promote electrolyte wetting
Electrochemical cell components such as interelectrode separators, retaining screens, and current collectors are contacted with lithium tetrachloroaluminate prior to contact with molten electrolytic salt to improve electrolyte wetting. The LiAlCl/sub 4/ can be applied in powdered, molten, or solution form; but, since this material has a lower melting point than the electrolytic salt used in high-temperature cells, the powdered LiAlCl/sub 4/ forms a molten flux prior to contact by the molten electrolyte when both materials are initially provided in solid form. Components of materials such as boron nitride and other materials that are difficult to wet with molten salts are advantageously treated by this process.
