The concept of self‐expanding lithium‐ion transport channels to construct a fast‐charging anode is proposed by Guoxing Li, Yuliang Li, and co‐workers in their Research Article (e202113313). The self‐expanding lithium‐ion transport channels can be achieved by a self‐reversible conversion of chemical bonds with different bond lengths in the anode driven by the interactions with lithium ions during cycling. They reduce the energy barrier of lithium‐ion transport, accelerate lithium‐ion solid‐state diffusion, and thus enable an excellent fast‐charging performance.
