Lithium‐Metal Anodes: A Lightweight 3D Cu Nanowire Network with Phosphidation Gradient as Current Collector for High‐Density Nucleation and Stable Deposition of Lithium (Adv. Mater. 48/2019)

A dense and stable lithium deposition process is highlighted by a snowy world, where the snowflakes represent the Li ions and the branches are like the ultralight 3D copper nanowire network with a phosphidation gradient employed by Wei Lv, Quan-Hong Yang, Feiyu Kang, and co-workers in article number 1904991. The gradient surface increases the lithiophilicity and high utilization of 3D structure, enabling a dendrite-free lithium-metal anode with high energy density.
