摘要: 超级电容器因具有高功率密度、长循环寿命和使用温度范围宽等显著优势,已成为化学电源产业内新的亮点。作为一种大功率储能器件,超级电容器在轨道交通、现代通讯、航空航天、国防等战略新兴领域具有广泛的应用前景,全球需求量迅速增长。目前,限制超级电容器规模应用的关键问题是其能量密度偏低以及成本过高。如何在保证其高功率密度和长循环寿命优势的前提下,提高超级电容器能量密度并降低其成本是当今研究的热点。近年来,全球的超级电容器研究者针对这一关键问题,从电极材料设计、新型电解液开发及器件构筑等方面开展了一系列的工作,从理论研究到工程应用都取得了重要的突破。本刊邀请了超级电容器领域内具有丰富研究经验的8个团队撰写了8篇关于超级电容器的综述或者研究论文,介绍了当前超级电容器领域的研究现状、发展趋势和所面临的挑战,希望籍此能使广大读者更加深入了解超级电容器这一领域,并共同推动我国超级电容器相关研究的进一步发展。在此,对本专辑的所有作者、审稿人及编辑部工作人员的卓有成效的工作和付出表示衷心的感谢!

Abstract: Supercapacitors (SCs) have become a new bright spot in electrochemical power source due to their high power density, long cycling life and wide operation temperature. As the high-power density energy storage devices, SCs have been widely applied in electric vehicle, modern communication, aerospace, defense, and many other emerging fields. The markets for SCs are continuously increasing. However, the commercialization of SCs suffers from a lower energy density and higher cost. Thus, one great challenge for the supercapacitor (SC) technology is to improve the energy density without sacrificing the power density and cycle life. To address this critical issue, the worldwide SC researchers have focused on design of electrode materials, developments in new-type electrolyte and assemble method of device. Many significant breakthroughs in theoretical studies and engineering applications have been achieved. In this special issue, we collect eight submissions including review and research articles from the leading research groups in SCs. The recent progresses, future trends and new challenges in the field of SCs researches have been presented and highlighted. We hope that this special issue may attract more attention from researchers to focus their studies on this booming field, and to promote the research and development of SCs in China. We would like to take this opportunity to thank all the authors, reviewers, and editorial staffs of Journal of Electrochemistry for their excellent and professional contributions to this special issue.
