Porphyrin Integration Enhances Bipolar Redox Accessibility for High-Rate Sodium-Based Dual-Ion Storage.
Closing the gap between theoretical multielectron capacity and practical accessibility remains the central bottleneck for high-energy organic batteries. Herein, we report a molecular design strategy that integrates a porphyrin motif into a sulfur-rich conjugated polymer (BTTP) to align electronic structure, state-depen...
