In the development of LiAl/FeS cells for electric vehicle propulsion and stationary batteries a considerable increase of perfrmance and cycle life of technical cells (140 Ah nominal capacity) has been achieved. These cells were fabricated with improved laminated MgO powder separators and vacuumtight brazed metal-ceramic feedthroughs. Specific energy of cells fabricated in small series is 100 Wh.kg-1, several hundred full cycles have been completed, the cells being still on test. The total materials cost of LiAl/FeS cells for a large scale production was estimated for a number of different cell designs. The cost range for cells with inexpensive MgO powder separators makes the LiAl/FeS system attractive for electric vehicle propulsion.
