Stable Anode‐Free All‐Solid‐State Lithium Battery through Tuned Metal Wetting on the Copper Current Collector (Adv. Mater. 8/2023)

All‐Solid‐State Batteries In article number 2206762, Yijie Liu, David Mitlin, and co‐workers report a stable anode‐free all‐solid‐state battery (AF‐ASSB) with a sulfide‐based solid‐electrolyte (argyrodite Li6PS5Cl). The battery is achieved by tuning the wetting of lithium metal on the “empty” copper current‐collector. In the cover image, the sprinting antelope represent the lithium cations rapidly diffusing through the solid‐state sulfide electrolyte with the blood‐red sunset behind them. The still water underneath represents the smooth lithium‐metal anode, while the mountains represent the dendrites, which the antelope avoid.
