Electrochemical cell and method of assembly. [Patent application]
A method of preparing an electrochemical cell is disclosed which permits the assembly to be accomplished in air. The cell includes a metal sulfide as the positive electrode reactant, lithium alloy as the negative electrode reactant, and an alkali metal, molten salt electrolyte. Positive electrode reactant is introduced as Li/sub 2/FeS/sub 2/, a single-phase compound produced by the reaction of Li/sub 2/S and FeS. The use of this compound permits introduction of lithium in an oxidized form. Additional lithium can be introduced in the negative electrode structure enclosed within an aluminum foil envelope between layers of porous aluminum. Molten salt electrolyte is added after assembly and evacuation of the cell by including an interelectrode separator that has been prewet with an organic solution of KCl. 2 figures, 2 tables.
