Abstract
A Li/SO2 battery, developed to power the AN/PRQ-501, Personal Locator Beacon (PLB), was found to explode on a number of occasions when discharged following a high frequency vibration test. These events took place in an engineering test lab in 1985. The initial investigation showed that the cell had been damaged in the vibration test so that the cold weld of lithium metal to cell wall had been torn. This had left a small piece of lithium, still attached to the can. It was therefore expected that the low rate (i.e., approximately 50mA) capacity would be diminshed from the normal 80 hours of service to about 3 hours. Explosions were totally unexpected and unexplained at that time.
