Polyrotaxane‐Assembled Semi‐Interpenetrating Polymer Electrolytes Enabling High‐Voltage Lithium Metal Batteries

Advanced Science, EarlyView.
This work develops a polyrotaxane‐based supramolecular semi‐interpenetrating network electrolyte. Its unique architecture decouples ion transport, achieving high ionic conductivity (0.18 mS cm−1), a superior Li+ transference number (> 0.73), and an extended electrochemical window (> 4.9 V), thereby significantly enhancing the performance of high ...

Beyond Cartilage‐Inspired Supramolecular Polyurethane for Adaptive Impact‐Resistant Protection with Robustness, Self‐Healing, and Recyclability

Advanced Science, EarlyView.
Cartilage‐inspired supramolecular polyurethane–urea (PU‐BAMB) elastomers are developed by integrating hierarchical hydrogen bonding and π–π stacking interactions within a dynamically reconfigurable network. This synergistic supramolecular architecture overcomes the intrinsic trade‐off between rigidity and recoverability, imparting exceptional toughness,
