Abstract

Because of their low electrical conductivity, sluggish ion diffusion, and poor stability, conventional electrode materials are not able to meet the growing demands of energy storage and portable devices. Graphene assembled films (GAFs) formed from graphene nanosheets have an ultrahigh conductivity, a unique 2D network structure, and exceptional mechanical strength, which give them the potential to solve these problems. However, a systematic understanding of GAFs as an advanced electrode material is lacking. This review focuses on the use of GAFs in electrochemistry, providing a comprehensive analysis of their synthesis methods, surface/structural characteristics, and physical properties, and thus understand their structure-property relationships. Their advantages in batteries, supercapacitors, and electrochemical sensors are systematically evaluated, with an emphasis on their excellent electrical conductivity, ion transport kinetics, and interfacial stability. The existing problems in these devices, such as chemical inertness and mechanical brittleness, are discussed and potential solutions are proposed, including defect engineering and hybrid structures. This review should deepen our mechanistic understanding of the use of GAFs in electrochemical systems and provide actionable strategies for developing stable, high-performance electrode materials.

石墨烯组装膜作为电化学反应平台的研究进展

传统电极材料导电性低，离子扩散缓慢，稳定性差，已不能满足日益增长的储能和便携式设备的需求。由石墨烯纳米片形成的石墨烯组装膜（gaf）具有超高导电性、独特的二维网络结构和卓越的机械强度，这使它们具有解决这些问题的潜力。然而，对gaf作为一种先进的电极材料缺乏系统的了解。本文综述了gaf在电化学中的应用，全面分析了其合成方法、表面/结构特征和物理性质，从而了解了它们的结构-性能关系。系统地评估了它们在电池、超级电容器和电化学传感器方面的优势，重点是它们优异的导电性、离子传输动力学和界面稳定性。讨论了这些器件存在的问题，如化学惰性和机械脆性，并提出了潜在的解决方案，包括缺陷工程和混合结构。这一综述将加深我们对gaf在电化学系统中应用的机理理解，并为开发稳定、高性能的电极材料提供可行的策略。下载：下载高分辨率图片（117KB）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.
