Regulating Steric Hindrance in Redox‐Active Porous Organic Frameworks Achieves Enhanced Sodium Storage Performance (Small 1/2022)

Sodium Ion Batteries Polymer electrodes have been significantly limited by poor reversible specific capacities, where a majority of aromatic C6‐benzene linkages are redox inactive. In article number 2105927, Xiang Zhu, Hao Jiang, and co‐workers show that decreasing steric hindrance of aromatic C6‐benzene rings within a porous organic framework affords a significant improvement in the redox reaction kinetics, thereby facilitating the acceptance of sodium ions on these rings and boosting overall battery performance.
