The main discharge products have been characterized and the effect of electrolyte properties on cell performance have been demonstrated. This paper describes the temperature performance of a lithium-oxygen battery using non-aqueous electrolyte and correlates this to changes in electrolyte viscosity with temperature. This paper presents the temperature performance of our baseline Li-O2 cell in the temperature range from -30°C to +40°C at discharge rates from 0.5 to 0.05 mA/cm2
