ABSTRACT:
This invention pertains to electrochemical cells, and specifically to an inner seal member in an electrochemcical cell. The inner seal member is positioned against, and in intimate contact with that portion of the separator which extends above the cathode mix, or a retaining washer on the cathode mix, and is also in intimate contact with the cathode mix or the retaining washer. The seal member is preferably emplaced as a fluid material and is preferably distributed by centrifugal force, by rotating the cell as the sealant material is dispensed into the cell. The inner seal member is effective to retard loss of battery performance over an extended period of storage time, both at room temperature and at elevated temperature. The seal member is a composition of hydrocarbons or fatty acid ester oils having the capacity to remain in full surface-to-surface contact, as it cools, with the surfaces upon which it is placed warm or hot, in the cell.
