Abstract
A prototype lithium sulphur dioxide battery, intended to power the AN/PRQ 501 Personal Locator Beacon, failed on discharge following high frequency vibration tests. The severity of the vibrational environment caused internal cell damage which weakened or detached the lithium electrode where it had been cold welded to the can. During discharge, individual cells having this defect would exhibit a loss of voltage followed by venting and subsequent explosion of the battery. Manufacturing improvements to the lithium-to-can weld, coupled with battery design features aimed at damping out vibrational effects have been successful in preventing this type of hazard. Research is underway to determine the electrochemical and/or thermal conditions which lead to such catastrophic failures.
