【摘要】 基于碳材料的超级电容器因其高功率密度、快速充放电能力而在电化学储能技术领域发挥着重要的作用，但是较低的能量密度严重限制其发展应用。相较于常规对称型超级电容器，非对称型超级电容器可以充分利用理论工作电压窗口，大幅拓宽工作电压进而提升整体能量密度。本文简单介绍了非对称型超级电容器的优势与分类，以及在电极电位拓宽策略方面的最新研究进展，为未来开发新型超级电容器提供参考方向。更多还原

【Abstract】 Carbon based supercapacitors play an important role in the field of electrochemical energy storage technology due to their high power density and fast charging and discharging capabilities, but their low energy density severely limits their development and application.Compared to conventional symmetric supercapacitors, asymmetric supercapacitors can fully utilize the theoretical working voltage window, significantly expand the working voltage, and thereby improve the overall energy density.This article briefly introduces the advantages and classification of asymmetric supercapacitors, as well as the latest research progress in electrode potential broadening strategies, providing reference directions for the future development of new supercapacitors.更多还原
