A Sodium–Antimony–Telluride Intermetallic Allows Sodium‐Metal Cycling at 100% Depth of Discharge and as an Anode‐Free Metal Battery (Adv. Mater. 1/2022)

Abstract
Anode-Free Batteries In article number 2106005, Hui Dong, David Mitlin, and co-workers report an intermetallic for anode-free batteries. The winter scene shows a birthday cake with lit candles that are melting: the cake represents the complex structure of a cycled sodium-metal anode with the protruding candles being the dendrites. A slice, obtained by cryogenic focused ion beam (FIB) microscopy, further reveals the underlying porosity that develops during repeated plating and stripping of the metal. The thick non-uniform red frosting on the cake represents the unstable solid electrolyte interphase (SEI) that drives the dendrite growth.
