Cathode material for use in a high temperature rechargeable molten salt cell and high temperature rechargeable molten salt cell including the cathode material

摘要

Binary sulfides of chromium of the formula Cr.sub.2 S.sub.3, Cr.sub.3 S.s4, and CrS are used as the cathode in a high temperature molten rechargeable salt cell. The cathode material is thermally stable at high temperatures and also provides high specific energy densities and specific power densities to that the cell can be used in pulse power, electric propulsion and load leveling applications.
