Abstract

Carbon dots (CDs) are functionalized carbon-based nanomaterials that have the potential for use in advanced batteries, owing to their ultrasmall size, tunable surface functional groups and excellent dispersibility. This review summarizes recent advances in CD-based materials for advanced batteries. Methods for the preparation of CDs are first introduced, focusing on the feasibility of large-scale synthesis, and four critical uses of CDs are analyzed: electrolyte solutions, metal electrode coatings, electrode materials, and solid-state batteries. We then consider how CDs suppress dendrite formation, decrease volume expansion, accelerate charge transfer, and improve ion migration. Finally, existing problems are discussed, including the industrial production of CDs, their role as additives in the evolution of electrode interfaces, and strategies for giving them multifunctionality.

用于先进电池系统的碳点

碳点（cd）是一种功能化的碳基纳米材料，由于其超小的尺寸、可调节的表面官能团和优异的分散性，在先进电池中具有潜在的应用前景。本文综述了近年来先进电池用cd基材料的研究进展。首先介绍了CDs的制备方法，重点介绍了大规模合成的可行性，并分析了CDs的四种关键用途：电解质溶液、金属电极涂层、电极材料和固态电池。然后我们考虑CDs如何抑制枝晶的形成，减少体积膨胀，加速电荷转移，并改善离子迁移。最后，讨论了目前存在的问题，包括cd的工业生产，它们作为添加剂在电极界面演变中的作用，以及赋予它们多功能性的策略。下载：下载高分辨率图片（166KB）下载：下载全尺寸图片

期刊介绍： New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
