高功率储能器件的研究进展

Research progress of high-power energy storage devices

由于技术原理不同,高功率储能器件在能量密度、功率特性和持续释能时间等方面差异较大,发展水平不一,所适用场景也不同。目前缺乏以单一技术特点为主线对典型高功率储能器件进行系统性梳理,使不同受用者对高功率储能器件有更加清晰的了解。本文概述了不同高功率储能器件的原理及适用场景,并从能量密度、功率密度、高功率特性等方面对各类高功率器件进行对比;重点以持续释能时间为轴线,对高功率储能器件水平现状进行分类论述,并对其未来发展方向进行总结讨论;最后,对高功率储能器件的发展作出展望。

The different high-power energy storage devices have different characteristics,such as energy density,power,and sustained release time,owing to their energy storage mechanisms,leading to the disequilibrium of the development level and different application scenarios.There is a lack of systematic arrangements for typical high-power energy storage devices based on a single technical featurethat helps customers have a clearer understanding of high-power energy storage devices.This study outlines the mechanisms and application scenarios of typical high-power energy storage devices and compares different characteristics of high-power energy storage devices,such as energy density,power,and sustained release time.The research progress of high-power energy storage devices is categorized and summarized based on sustained release time.Moreover,an outlook on the development of high-power energy storage devices is presented.
