Method of preparing a positive electrode for an electrochemical cell
A method of preparing an electrochemical cell including a metal sulfide as the positive electrode reactant and lithium alloy as the negative electrochemical reactant with an alkali metal, molten salt electrolyte is disclosed which permits the assembly to be accomplished in air. The electrode reactants are introduced in the most part as a sulfide of lithium and the positive electrode metal in a single-phase compound. For instance, Li/sub 2/FeS/sub 2/ is a single-phase compound that is produced by the reaction of Li/sub 2/S and FeS. This compound is an intermediate in the positive electrode cycle from FeS/sub 2/ to Fe and Li/sub 2/S. Its use minimizes volumetric changes from the assembled to the charged and discharged conditions of the electrode and minimizes electrode material interaction with air and moisture during assembly.
