Abstract :
The author reports on an accelerated synchronous orbit life test of a five-cell, Li-TiS2 battery. The five-cell battery is comprised of experimental cells of advanced design that were obtained from the Jet Propulsion Laboratory (JPL). A charge/discharge, state-of-charge control scheme with taper charge current control is used to reduce the deleterious effects of high end-of-charge and low end-of-discharge voltages. The results of this Li-TiS2 battery test show a capability that should lead to success in meeting a 10-orbital year goal with near-term cell improvements
