Abstract

Carbon dots (CDs), as emerging members of the carbon nanomaterial family with ultra-small sizes and unique physicochemical properties, which has attracted a great deal of attention in energy conversion and storage, especially in rechargeable batteries in recent years. Although CDs have shown remarkable potential in different batteries, the mechanism of its role for solving common problems in batteries is lacking. In this review, we first clarify the constitutive relationship between the preparation, modification and electrochemical properties of CDs and provide strategies for structural design. Notably, we categorize the role of CDs in batteries from a new perspective, detailing the mechanism that CDs function in different electrochemical properties. Finally, we provide several issues facing CDs in battery applications and directions for further research. This review is expected to serve as an insightful guidance for scientists who work with the fascinating material of CDs and to stimulate further exploration in energy storage.

从结构工程到电池机制的新视角解密碳点

碳点（CD）作为碳纳米材料家族中的新兴成员，具有超小尺寸和独特的物理化学特性，近年来在能量转换和储存领域，尤其是充电电池领域引起了广泛关注。虽然 CD 在不同的电池中都显示出了巨大的潜力，但其在解决电池中常见问题方面的作用机理还缺乏研究。在这篇综述中，我们首先阐明了 CD 的制备、改性和电化学性能之间的构成关系，并提供了结构设计策略。值得注意的是，我们从一个新的角度对光盘在电池中的作用进行了分类，详细介绍了光盘在不同电化学特性中的作用机制。最后，我们提出了 CD 在电池应用中面临的几个问题以及进一步研究的方向。希望这篇综述能为研究 CD 这种神奇材料的科学家提供有见地的指导，并激励他们在储能领域进行进一步的探索。
