Considerable progress has been made concerning elucidation of existing problems through use of factorial design of experiments as well as use of conventional test methods. A re-usable multicell test fixture has been developed which increases the number of multicell tests possible per unit time. Investigation of the hot battery failure mode has led to the disclosure of a gassing reaction at the cathode. This information was obtained through use of reference cells which denoted the limiting plate and through use of clear plastic cell blocks which enabled observation of gassing action. Cause of this phenomenon has not been isolated or corrected as yet. Correction of this difficulty should result in much improved multicell performance. Author
