The Air Force is developing sodium-sulfur rechargeable batteries for satellite baseload power applications. This technology has been selected for development due to its high energy density and high energy efficiency. The major technical problem to overcome before these cells can be operationally used is the life of the battery cells. All previous tests of these cells, and thus all life data that exist, were based on terrestrial battery requirements such as electric vehicles and load leveling systems. The sodium-sulfur cell tests being conducted at Wright-Patterson AFB are simulating mid-altitude and geosynchronous orbits. The results of these tests so far are very encouraging, with over 1300 cycles collected on the oldest cells and no failures due to cycling.
