In general the technology of lithium-aluminium-iron sulphide cells for electric vehicle applications is now estalished but needs evolutionary improvements to become fully commercial. 

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.

The electrolyte used in lithium (aluminium)-iron sulphide secondary cells is commonly a mixture of lithium chloride and potassium chloride. A lithium fluoride-lithium chloride-lithium bromide mixture has also been used. With the latter electrolyte the discharge occurs in two steps ... 

A further improvement on the lithium anode-iron sulphide (FeS2) thermal cell is one in which the anode consists of a lithium alloy (usually lithium-aluminium alloy, although lithium-silicon and lithium-boron...
