Recently, extensive research efforts on electrochemical energy storage materials have been developed, motivated by the urgent need for efficient energy storage devices for the automotive market. Electrochemical capacitors (ECs) bridge the gap between batteries and solid-state and electrolytic capacitors. While the high power density of these devices is attractive, greater energy density is required for the future. To address this need, both experimental approaches that modify the electrolyte–electrode interface and the use of analytical methods to characterize these interfaces are being actively pursued. The development of advanced in situ analytical techniques to understand fundamental electrochemical processes and structural effects (pores, surface groups) down to the nanoscale level is expected to play a key role in developing the next generation of ECs with high energy and high power performance.

电化学电容器的未来发展方向

最近，由于汽车市场对高效储能设备的迫切需求，已经对电化学储能材料进行了广泛的研究。电化学电容器 (EC) 弥合了电池与固态和电解电容器之间的差距。虽然这些设备的高功率密度很有吸引力，但未来需要更高的能量密度。为了满足这一需求，正在积极寻求修改电解质-电极界面的实验方法和使用分析方法来表征这些界面。先进的原位开发了解基本电化学过程和结构效应（孔、表面基团）到纳米级的分析技术有望在开发具有高能量和高功率性能的下一代 ECs 中发挥关键作用。
