INVESTIGATION OF HERMETICALLY SEALED MAINTENANCE-FREE, HIGH RATE, NICKEL-CADMIUM BATTERIES FOR AIRCRAFT APPLICATIONS
Abstract
The objectives of this program are to design, develop and fabricate hermetically sealed, maintenance-free, high rate, nickel-cadmium batteries for aircraft applications. The battery must be capable of delivering the necessary power for engine starting, it must be capable of withstanding the varied environmental conditions that may prevail in an aircraft, and it must be compatible with the constant potential charging system of the aircraft. To achieve these objectives: A basic research program has been undertaken with the ultimate goal of improving the electrochemical operation of sealed nickel- cadmium cells. Improvements sought include longer shelf life, better electrical performance at high rates of charge and discharge, and better electrical performance at high and low temperature extremes. To make the battery compatible with the constant potential charging system of the aircraft, a charge cntrol- charge conditioning system is being studied to allow rapid charging of the battery when it needs to be recharged. When the battery becomes fully charged, the charge control-charge conditioning system must also be capable of terminating the charging current on signal from an end-of-charge signal generating device.
