Abstract
A prototype lithium sulphur dioxide battery, intended to power the AN/PRQ 501 Personal Locator Beacon (PLB), failed on discharge following high frequency vibration tests. The severity of the vibrational environment resulted in damage to the lithium electrode. During discharge, individual cells having this defect lost voltage, vented and exploded. This safety hazard has since been corrected with a cell design where the lithium-to-can weld is more durable. In addition, better tolerance to high frequency vibration and resonance effects was achieved by an improved battery package design. A new technical specification for the PLB battery is described to assure a high degree of safety and performance over a wide range of temperatures and environmental conditions.
