Corrosion resistance of lithium/iodine batteries fabricated in an extremely dry environment
Early lithium/iodine pacemaker batteries employed considerable amounts of inert plastic materials to encase the active ingredients inside the stainless steel case. Several years ago the Wilson Greatbatch Ltd. (WGL) Model 755 cell was introduced and represented a significant change in lithium/iodine battery construction. In this design (1) the iodinepolyvinylpyridine (PVP) depolarizer material was placed in direct contact with the 304L stainless steel case and much of the inert material was eliminated. This change resulted in obtaining substantially more depolarizer in the battery thereby greatly increasing the electrical capacity for the same cell volume. A study was instituted to evaluate possible corrosion effects between the iodine in the depolarizer and the stainless steel case.
