What is Passivation in a primary battery? (video)
Passivation is the main "observable" effect of a surface reaction that occurs spontaneously onto lithium metal surfaces in all primary Lithium batteries based on a liquid cathode. The corrosion of lithium metal by liquid Thionyl Chloride into lithium ions leads to the formation of a solid protecting layer, the " passivation layer ".
