Abstract

Abstract : In article number 2003769, Myung‐Hyun Ryou, Hongkyung Lee, Yong Min Lee, and co‐workers report a LiNO3 pre‐planted lithium metal powder (LN‐LMP) electrode, practically designed for ultra‐thin and wide electrode fabrication. The pre‐planted LiNO3 allows not only chemically induced uniform nitration of the LMP surface but also steady release into the electrolyte during cycling, leading to sustainable solid electrolyte interphase stabilization during further cycling. By benefiting from these effects, the LN‐LMP electrode enables highly reversible Li plating/stripping over the entire surface even in a corrosive carbonate‐based electrolyte system.
