Lithium AA-Size Cells for Navy Mine Applications: 2. Evaluation of CommercialCells

摘要

The discharge performance of five commercial AA-size lithium cells has beenevaluated to determine the feasibility of incorporating them into various battery packages for future Naval mine applications. Fresh cells and cells stored for varying durations at high temperature were discharged at (1) ambient room temperature at a low rate (3 mA) and (2) at a low temperature (-2 C) and 3 mA, 20 mA, and 50 mA rates including some with pulse applications. The Li/SOCl2 cells generally met all of the stringent performance requirements for mine operations. Specific test results often varied from manufacturer to manufacturer. The Li/MnO2 technology failed to provide sufficient capacity when discharged at -2 C at 20 mA after high temperature storage and was also unable to provide high current pulses at -2 C.
