New lithium oxyhalide reserve battery technology

Abstract

A high power, light weight lithium oxyhalide reserve battery has been developed for the Theater High Altitude Area Defense (THAAD) missile program under sponsorship of the Atmospheric Interceptor Technology (AIT) program. This battery has two electrically isolated sections composed of 8 and 9 cells combined in series to provide required power when operating between 24.0 volts and 34.5 volts. One section provides 400 watts average power, while the other section provides a highly varied load that averages 200 watts. The battery has proven itself capable of sustaining this level of loading in excess of 360 seconds in environmental conditions ranging from -20/spl deg/C to 55/spl deg/C. This battery completed qualification to the requirements of the THAAD KV Battery Specification on August 25, 1999.
