Lithium Metal Batteries: Cross Talk between Transition Metal Cathode and Li Metal Anode: Unraveling Its Influence on the Deposition/Dissolution Behavior and Morphology of Lithium (Adv. Energy Mater. 21/2019)

In article number 1900574, Martin Winter, Tobias Placke, and co‐workers report on the cross‐talk phenomena between the positive electrode materials LiNi0.5Mn1.5O4 (LNMO), LiNi0.6Mn0.2Co0.2O2 and LiFePO4 and the negative Li metal electrode, i.e., the cross‐over of transition metals dissolved in the electrolyte, especially visible for Li metal ‖ LNMO cells. This work uncovers the need for thorough investigations of Li metal negative electrodes in full cells with a transition metal positive electrode.
