Lithium Ambient-Temperature Battery Reliability Program, May 1983-April 1985

From May 1983 through April 1985 Sandia National Laboratories continued to develop and evaluate nondestructive methodology for predicting the reliability of primary lithium batteries. During this period, considerable time was spent improving the microcalorimetry data acquisition and processing software and completing the curve-fitting algorithm for the impedance data. All initial measurements were conducted, and all cells either completed the storage portion of the text matrix or remained in storage. Some statistical analyses were completed. Several nondestructive measurement variables that correlate well with remaining capacity were identified. Finally, the status of the program was evaluated and the program was tentatively extended to October 1986.
