Solution‐Processable Thermally Crosslinked Organic Radical Polymer Battery Cathodes

Get radical: A one-step post-synthetic crosslinking method that is compatible with solution processing is developed to improve the performance of organic polymer electrodes. The highest electrode capacity of 104 mAh g−1 (vs. a theoretical capacity of 111 mAh g−1) is achieved by introducing 1 mol % crosslinker, whereas the highest capacity retention (99.6 %) is obtained with 3 mol % crosslinker.
