Use of the Li-Al/FeS battery in advanced vehicle propulsion systems

The lithium/molten salt system provides for a family of batteries with lithium as the electrochemically active element and a molten salt mixture containing lithium as the electrolyte. The basic concept of the Li-Al/FeS battery is given, and its status is compared to aqueous batteries and other advanced couples. Research work on more energetic couples such as Li-Si, FeS/sub 2/ and pure lithium is underway as well as Li-Al. Ongoing programs are summarized, one of which involves an electrified Chrysler T-van that uses a Li-Al/FeS battery. (LEW)
