开发更有效的电力存储是满足未来社会和环境需求的迫切要求。这种对更可持续、更有效的能量存储的需求，激发了人们对先进电容器设计的新的科学和商业兴趣，其中包括纳米技术的实验技术和想法正在发挥关键作用。电容器可以快速充电和放电，是从微处理器到大型电源的许多类型电路的主要组成部分之一，但与电池相比，电容器的储能能力通常相对较低。正在深入研究具有定制形态和性质的纳米结构材料在电化学超级电容器中的应用，以便在不包括其固有的高功率密度和优异的循环性的情况下提供增强的能量密度。特别地，预见利用电解质离子的物理吸附或氧化还原反应的电极材料来弥合具有高能量密度的电池与具有高功率密度的电容器之间的性能差异。在这篇综述中，我们提出了一些新的纳米材料系统应用于电化学超级电容器，并显示如何材料的形态，化学和物理性质被定制，以提供增强的电化学超级电容器性能。
The development of more efficient electrical storage is a pressing requirement to meet future societal and environmental needs. This demand for more sustainable, efficient energy storage has provoked a renewed scientific and commercial interest in advanced capacitor designs in which the suite of experimental techniques and ideas that comprise nanotechnology are playing a critical role. Capacitors can be charged and discharged quickly and are one of the primary building blocks of many types of electrical circuit, from microprocessors to large-sale power supplies, but usually have relatively low energy storage capability when compared with batteries. The application of nanostructured materials with bespoke morphologies and properties to electrochemical supercapacitors is being intensively studied in order to provide enhanced energy density without comprising their inherent high power density and excellent cyclability. In particular, electrode materials that exploit physical adsorption or redox reactions of electrolyte ions are foreseen to bridge the performance disparity between batteries with high energy density and capacitors with high power density. In this review, we present some of the novel nanomaterial systems applied for electrochemical supercapacitors and show how material morphology, chemistry and physical properties are being tailored to provide enhanced electrochemical supercapacitor performance.
