Abstract

The electrochemical reactivity of lithium and similar alkali metals has been widely explored because of the interest in these materials for high energy density batteries both primary and secondary cells. The studies presented in this paper focus on the electrochemical characterization of lithium thin films prepared in an atomically clean state in an ultra-high vacuum chamber and then transferred to an electrochemical cell consisting of SO2-saturated acetonitrile. The role of prior oxidation with small and large doses of gaseous O2 and H2O in the UHV preparation chamber is also explored, along with the role that prolonged solution immersion times of these same surfaces prior to discharge has on the ultimate electrochemical reactivity.
