<p>Electrochemical cells where the cathode preferably comprises an electroactive sulfur-containing material and the anode preferably comprises lithium, and the cells deliver a high percentage of the theoretical discharge capacity, exhibit high charge- discharge efficiency, and/or show low self-discharge rates. The cells comprise one ore more N-O additives and at least one of the N-O additives comprises a nitrate.</p> |
