Levy, S C

A 6-year test program to evaluate an ambient-temperature Li primary battery was initiated on cells from two manufacturers. Three modes of premature failure were observed in Li/SO/sub 2/ cells: corrosion of the lithium-to-can contact, corrosion of the glass in the glass-to-metal seal in the header, and corrosion at the Al-Ta weld in the positive lead. Potential fixes for each of these failure modes were incorporated into cells from two suppliers, and accelerated tests of these cells have begun. 2 figures, 1 table. (RWR)
