The electrolyte comprises a lithium salt dissolved in a nonaqueous solvent mixture which contains a tin iodide (SnI2) additive. A cathode slurry is prepared comprising iron disulfide powder, carbon, binder, and a liquid solvent. The mixture is coated onto a conductive substrate and solvent evaporated leaving a dry cathode coating on the substrate. The anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added.
