Nickel/Cadmium Aircraft Batteries: Failure Prediction in Battery Shops by Gassing Rate Measurements.
Abstract
One of the serious problems which face a battery shop responsible for maintenance of nickel/cadmium aircraft batteries is to identify cells which would be likely to fail during the next period of service on board the aircraft. At present it seems that nearly all of the catastrophic battery failures which arise on board are due to failure of the separator materials in the cells. In the majority of cases it is likely that gradual deterioration of the separators takes place over a period of time at a rate which in large measure depends on the details of the stress to which the battery is subjected, and in particular to the thermal stress involved. This document discusses two modes of failure due to separator deterioration and how the deterioration may be detected at an early stage by measurement of gas emission.
