Advanced Functional Materials, EarlyView.This work develops flexible zinc‐ion batteries (FZIBs) using a zincophilic/hydrophobic polymer (thermoplastic polycarbonate‐based polyurethane, TPCU) to protect Zn powder anodes and MXene/Silk (MXS) as flexible current collectors. The designed TPCU‐ZnP@MXS structure enables uniform Zn deposition, yielding dendrite‐free anodes with stable cycling ...
