The entrapment of free‐lithium in a 3D fibrous Li 7 B 6 framework produces a LiB nanostructured anode with a stable interface. This structure is demonstrated by Q. Zhang and co‐workers on page 4257. The nanostructured anode not only reduces the areal current density that lowers the growth velocity of lithium deposits, but also limits the final size of the deposited lithium, which leads to a dendrite‐free morphology at the macroscale.
