The second molten salt battery to have received detailed attention is the lithium/ iron sulphide battery. During discharge, the negative electrode reaction is the dissolution of Hthium from a lithium/aluminium alloy (10—20% Li), while the positive electrode reaction is the reduction of iron disulphide which occurs in stages...

The better performance of the FeS2 electrode cells vis a vis the FeS cells led to these becoming the focus of the lithium-aluminium/iron sulphide battery development programme at Argonne. In 1986 a life of 1000 cycles was achieved on prismatic cells with flooded electrolyte and dense electrodes operating on the upper voltage plateau.

Eagle Richer entered into the development of the lithium-metal sulphide battery system for vehicle propulsion in 1975. The electrochemical system under study utilizes an anode of a lithium-aluminium alloy and a cathode of the metal sulphides. Iron sulphide (FeS) or iron disulphide (Fe 2) is currently most commonly utilized. Initial efforts were directed toward... 

Westinghouse are developing a 36 V electric vehicle lithium-aluminium-iron sulphide battery which has a specific energy of 112 W h/kg on the basis of cell mass and 98 W h/kg on the basis of battery module weight including heat dissipating system. 

Mine Safety Appliances have also designed a system with lithium as the active anode material and ferrous sulphide as the cathode, which shows significant improvements in performance over the conventional systems (Table 60.8). The lithium-iron sulphide system is based on a pile-type construction, which allows the battery voltage to be easily adjusted.
