Organic radicals are crucial intermediates generated during the redox processes of organic electrode materials. However, the poor stability of organic radicals often results in the capacity fade of organic electrodes, and their stabilization mechanism is rarely explored. Additionally, the structure-property relationship between the organic radicals and the resultant organic electrodes is rarely reported. Therefore, finely regulating the stability of organic radicals to optimize the electrochemical performance of organic electrodes remains a significant challenge.
