Abstract : New test equipment and special demountable cells were designed and constructed for use in preliminary assessment of newly proposed accelerated life tests. Cycling tests were performed on groups of five cells each at ambient temperatures of -20, -5, 10, 25, and 40 C, and both with and without temperature gradients. The special demountable cells with internal heaters were used to provide an internal cell temperature of 40 C for those cells with temperature gradients. (Author)
