Directional Regulation of Zinc Deposition Through Constructing Hierarchical Janus Carbon Matrix with Organic‐Decorated Multi‐Channels

Advanced Science, EarlyView.
A Janus carbon matrix is engineered by covalently anchoring organic sulfonic anions within tubular pores of hierarchical CMK‐5, serving as an interfacial layer for Zn metal anodes. This design establishes a charge gradient for Zn2+ diffusion, enabling the directional deposition of confined and uniform Zn inside the pores while suppressing parasitic ...
