With the increasing requirements for high energy density, long lifetime, high safety, environmentally friendly fabrication, and sustainable development of large energy storage devices, the society calls for new electrode materials in rechargeable batteries beyond traditional inorganic materials which are limited by specific capacity. Organic electrode materials have been widely used in rechargeable batteries due to their advantages of large theoretical capacity, designable structures and environmentally friendly fabrications. In this review, the radical intermediates of organic electrode materials produced in the charging-discharging process (redox reaction) and their types are systematically reviewed. The stability of radical intermediates controlled by changing the structure of materials, and thereby, the optimization in the electrochemical performance of organic electrode materials are described. The reasons for the optimization of electrochemical performance are analyzed in depth, and the mechanism is discussed. This review provides guidance for improving the electrochemical performance of secondary batteries with organic materials as electrodes in the future.
