Abstract

A molten salt cell is described in which a special material is used as the active material in the negative electrode. Such active material permits extensive cycling of the battery and does not significantly alter cell voltage. Molten salt cells made in accordance with this invention exhibit high energy content and high discharge rates. In addition, they can be cycled extensively without significant loss of capacity.
