Method for preparing a sodium/sulfur cell
A method for preparing a sodium/sulfur cell comprises inserting a solid sodium slug, adapted to be connected to an external circuit, into the anodic reaction zone of a cell subassembly maintained within an inert atmosphere. The cell subassembly comprises a cell container and a tubular cation-permeable barrier disposed within the container such that a first reaction zone is located within cation-permeable barrier and a second reaction zone is located between the outer surface of the cation-permeable barrier and the inner surface of the container. One of the reaction zones is the anodic reaction zone and the other of the reaction zones is a cathodic reaction zone containing a precast composite cathodic reactant comprising a sulfur-impregnated porous conductive material connected to the cation permeable barrier and adapted to be connected to the external circuit. The preperation method also provides closure means for the subassembly and seals it to the subassembly at a temperature less than about 100/sup 0/ C. The method of the invention overcomes deficiencies of the prior art methods by allowing preparation of a sodium/sulfur cell without the use of molten reactants and the fill spouts that are required when the cell is filled with molten reactants. 1 figure.
