Saft America Lithium Sulfur Dioxide Battery (P/N 38303301) for FLYRT Application: Performance Discharge Test Report.

摘要

The Battery Technology Group of the Electrochemistry Branch (Code R33) of the Naval Surface Warfare Center, White Oak Detachment, was tasked by the Countermeasures Group of the Naval Research Laboratory to execute a series of performance discharge tests on a Li/SO2 battery. The battery was designed and assembled by SAFT America (P/N 38303301) to be used for the Flying Radar Target (FLYRT) Demonstration Program. The preliminary battery tests included discharge tests designed to determine the ability of the SAFT America battery to deliver a nominal 600 watts for 10 to 12 minutes within the voltage range of 66 to 100 volts. The battery was tested insulated in some cases to determine the effects of an adiabatic environment on its performance. The battery exceeded the goals set for power and lifetime in all tests. However, events consistently occurred at the end of battery life that raised safety concerns with the present battery design. Data were also analyzed for voltage delay characterization; no serious voltage delay problems were evident.
