Designing and Demystifying the Lithium Metal Interface toward Highly Reversible Batteries (Adv. Mater. 52/2021)

Lithium‐Metal Anodes In article number 2105962, Jia‐Qi Huang and co‐workers report the fabrication of a highly reversible working Li‐metal anode by synergistically modulating the solid electrolyte interphase chemistry and Li nucleation. Combined techniques are employed to demystify the initial formation and evolution scenarios of the Li‐metal interface, providing critical insights into the design guidelines of high‐efficiency Li‐metal batteries. A precisely designed interface enables highly reversible lithium deposition, analogous to the reliable shuttle of a spacecraft between the Earth and the moon.
