摘要

超级电容器(SCs)是一种潜在的可靠的能量存储设备,因此受到了研究人员的极大关注。然而,由于有限的电容和低能量密度,仍有改进的余地。开发增强其电化学特性的新方法的竞赛仍然很激烈,其目标是通过增加其比电容和提高其工作电压来提高其能量密度,以与电池相匹配,同时保持高功率能力并降低生产成本。鉴于此,本文简要总结了高能量密度超导材料的研究现状和新见解,以期对超级电容器研究领域的新研究人员有所帮助。从电解质、电极和设备修改的角度,强调和探索了新的适用方法。与传统的超级电容器相比,电极材料/复合材料和电解质的特殊组合及其制造设计大大提高了超级电容器的电化学性能和能量密度。重点放在与SCs能量存储过程相关的动态和机械变量上。为了指出高能超导设计的积极未来,最后强调了其潜力和困难。进一步探讨了提高超级电容器能量密度的几个重要课题,以及主要影响因素之间的一些联系。本文还讨论了这一引人入胜的课题的障碍和前景。这给了超级电容器的基本理解,以及下一代改进的超级电容器正在开发用于商业和消费者使用的关键设计原则。

High Energy Density Supercapacitors: An Overview of Efficient Electrode Materials, Electrolytes, Design, and Fabrication

Supercapacitors (SCs) are potentially trustworthy energy storage devices, therefore getting huge attention from researchers. However, due to limited capacitance and low energy density, there is still scope for improvement. The race to develop novel methods for enhancing their electrochemical characteristics is still going strong, where the goal of improving their energy density to match that of batteries by increasing their specific capacitance and raising their working voltage while maintaining high power capability and cutting the cost of production. In this light, this paper offers a succinct summary of current developments and fresh insights into the construction of SCs with high energy density which might help new researchers in the field of supercapacitor research. From electrolytes, electrodes, and device modification perspectives, novel applicable methodologies were emphasized and explored. When compared to conventional SCs, the special combination of electrode material/composites and electrolytes along with their fabrication design considerably enhances the electrochemical performance and energy density of the SCs. Emphasis is placed on the dynamic and mechanical variables connected to SCs′ energy storage process. To point the way toward a positive future for the design of high-energy SCs, the potential and difficulties are finally highlighted. Further, we explore a few important topics for enhancing the energy densities of supercapacitors, as well as some links between major impacting factors. The review also covers the obstacles and prospects in this fascinating subject. This gives a fundamental understanding of supercapacitors as well as a crucial design principle for the next generation of improved supercapacitors being developed for commercial and consumer use.

期刊介绍: The Chemical Record (TCR) is a "highlights" journal publishing timely and critical overviews of new developments at the cutting edge of chemistry of interest to a wide audience of chemists (2013 journal impact factor: 5.577). The scope of published reviews includes all areas related to physical chemistry, analytical chemistry, inorganic chemistry, organic chemistry, polymer chemistry, materials chemistry, bioorganic chemistry, biochemistry, biotechnology and medicinal chemistry as well as interdisciplinary fields. TCR provides carefully selected highlight papers by leading researchers that introduce the author''s own experimental and theoretical results in a framework designed to establish perspectives with earlier and contemporary work and provide a critical review of the present state of the subject. The articles are intended to present concise evaluations of current trends in chemistry research to help chemists gain useful insights into fields outside their specialization and provide experts with summaries of recent key developments.
