Abstract
The Air Force Research Laboratory (AFRL), Energy Storage and Thermal Sciences (PRPS) Branch has been developing nickel-metal hydride (Ni-MH) rechargeable batteries as an environmental replacement for existing valve regulated lead-acid (VRLA) and vented/sealed nickel-cadmium (VNC/SNC) batteries since 1995 and has evaluated cylindrical, prismatic and bipolar designs for this application. Recent advances in cell chemistry and design have resulted in a significant improvement in ultra low temperature performance indicating the suitability of these batteries for military aircraft applications over the temperature range from -40 °C to +65 °C. Results of the latest in-house tests of developments in bipolar and prismatic cell and battery designs indicate the current prismatic cell formulations are limited to temperatures above -25 °C while those used in bipolar designs operate over the full military aircraft temperature regime.
