摘要

集流器是锂离子电池和超级电容器装置中的关键部件,负责从电极材料中收集电子并将其导入外部电路。然而,随着电池系统的发展和对更高能量密度需求的增加,传统集流器的局限性(如高接触电阻和低耐腐蚀性)日益明显。本综述研究了现代电池和超级电容器系统中与集流器相关的功能和挑战,尤其侧重于使用碳涂层方法来提高集流器的性能。表面涂层以其简便性和广泛适用性而著称,是应对这些挑战的一种有前途的解决方案。本综述全面概述了锂离子电池和超级电容器中各类金属和非金属基底的碳涂层集流体,包括涂层材料和技术的比较分析。报告还讨论了碳涂层集电体的制造方法及其对行业的实际影响。此外,该综述还探讨了前景和机遇,强调了下一代高性能涂层的开发,并强调了先进集流器在优化能源设备性能方面的重要性。

Carbon-coated current collectors in lithium-ion batteries and supercapacitors: Materials, manufacture and applications

Carbon-coated current collectors in lithium-ion batteries and supercapacitors: Materials, manufacture and applications
The current collector is a crucial component in lithium-ion batteries and supercapacitor setups, responsible for gathering electrons from electrode materials and directing them into the external circuit. However, as battery systems evolve and the demand for higher energy density increases, the limitations of traditional current collectors, such as high contact resistance and low corrosion resistance, have become increasingly evident. This review investigates the functions and challenges associated with current collectors in modern battery and supercapacitor systems, with a particular focus on using carbon coating methods to enhance their performance. Surface coating, known for its simplicity and wide applicability, emerges as a promising solution to address these challenges. The review provides a comprehensive overview of carbon-coated current collectors across various types of metal and nonmetal substrates in lithium-ion batteries and supercapacitors, including a comparative analysis of coating materials and techniques. It also discusses methods for manufacturing carbon-coated current collectors and their practical implications for the industry. Furthermore, the review explores prospects and opportunities, highlighting the development of next-generation high-performance coatings and emphasizing the importance of advanced current collectors in optimizing energy device performance.
