ABSTRACT:
In lithium iodine electrochemical cells, control of polyvinylpyridine film thickness and/or polyvinylpyridine film surface area coverage and/or control of the quantity thereof on or with respect to the lithium anode operative surface directly affects cell voltage characteristics during discharge, allowing the tailoring of the voltage characteristics near cell end-of-life (EOL) in a useful way.
