The secondary lithium metal negative electrode is regarded as the “end point” in closed form electrochemical energy systems. The inherent instability of the lithium metal interface against any known electrolyte and current collector makes any resultant passivation layer and alloys a critical aspect of the electrodeposition, and stripping, of the metal in addition to standard electrochemical determinants of plate metal morphology. In this presentation we present the conditions that result in a columnar morphology of lithium grown atop copper films, as well as the electrochemical behavior of this morphology as compared to standard foil lithiums.
