Morphology optimization of organic electrodes with more exposed redox-active sites and large contact area between active materials conductive carbon is crucial for higher actual capacity, improved rate performance, however, also challenging. In this work, we report a self-assembled perylene diimide disodium salts (PDI-ONa)-based cathode sodium batteries (SOBs) unveil an in situ electro-induced reorganization process that optimizes the nanostructured morphology significantly improves ionic electronic transport. Experimental theoretical data suggest such driven by continuous dissociation/restacking PDI-ONa during cycling. The resulting reorganized electrode exhibits excellent (136 126 mA h g–1 at 0.2 100 A g–1) cycling performance (141 after 24,000 cycles 3 g–1). Even −30 °C, it can perform well (140 500 0.1 Our findings provide fresh perspective on optimizing high-performance SOBs.
