Carbon-based materials (CBMs) have shown great versatility because they can be chemically combined with other materials for various applications. Chemical modification of CBMs can be achieved via covalent or non-covalent interactions. Non-covalent interactions are weak and fragile, causing structural change and molecule dissociation. Therefore, in this review, we summarize the covalent modification of CBMs via organic chemistry techniques, aiming at forming more robust and stable CBMs. Besides, their application as electrode materials in energy storage systems is also within the scope of this review. Covalent binding of redox-active organic molecules with CBMs improves the transfer rate of electrons and prevents the dissolution of redox-active molecules, resulting in good conductivity and cycle life. Numerous papers on the functionalization of CBMs have been published to date, but some of them lack scientific evidence and are unable to understand from chemistry viewpoint. Reliable articles with adequate evidence are summarized in this review from a synthetic chemistry viewpoint.
碳基材料（CBMs）具有很强的通用性，因为它们可以与其他材料进行化学结合以用于各种应用。CBMs的化学修饰可以通过共价或非共价相互作用实现。非共价相互作用较弱且不稳定，会导致结构变化和分子解离。因此，在本综述中，我们总结了通过有机化学技术对CBMs进行的共价修饰，旨在形成更坚固、稳定的CBMs。此外，它们作为储能系统电极材料的应用也在本综述范围内。氧化还原活性有机分子与CBMs的共价结合提高了电子转移速率，并防止氧化还原活性分子溶解，从而产生良好的导电性和循环寿命。迄今为止，已经发表了许多关于CBMs功能化的论文，但其中一些缺乏科学依据，无法从化学角度理解。本综述从合成化学角度总结了有充分证据的可靠文章。
