电化学电容器，也称为超级电容器，正在成为能量存储中越来越重要的组件，尽管由于高成本/性能比，它们的广泛使用尚未实现。基础研究通过新材料的工程设计有助于降低成本。目前，电化学电容器中使用的最可行的材料是生物质衍生的和聚合物衍生的活性炭，尽管其他碳材料也是有用的研究工具。金属氧化物可以导致电化学电容器技术的一个步骤的变化，是一个令人兴奋的研究领域。选择合适的电解质和电极结构是决定器件性能的基础。尽管在理解电化学电容器的基本机制方面仍存在许多不确定性，但仍在继续取得真正的进展。有人认为，一个大的，合作的国际研究计划是必要的，以充分开发电化学电容器的潜力。
Electrochemical capacitors, also known as supercapacitors, are becoming increasingly important components in energy storage, although their widespread use has not been attained due to a high cost/ performance ratio. Fundamental research is contributing to lowered costs through the engineering of new materials. Currently the most viable materials used in electrochemical capacitors are biomass-derived and polymer-derived activated carbons, although other carbon materials are useful research tools. Metal oxides could result in a step change for electrochemical capacitor technology and is an exciting area of research. The selection of an appropriate electrolyte and electrode structure is fundamental in determining device performance. Although there are still many uncertainties in understanding the underlying mechanisms involved in electrochemical capacitors, genuine progress continues to be made. It is argued that a large, collaborative international research programme is necessary to fully develop the potential of electrochemical capacitors.
