摘要

双电层电容器(EDLC)在电力系统的平稳运行中得到了广泛的应用。然而,要将EDLC成功融入能源互联网,需要全面了解其在各种运行条件下的电气响应。本文采用分子动力学模拟的方法研究了EDLC放电过程中短时记忆效应的物理机制。通过电阻器和电容器传输线模型的等效电路,揭示了恒相元件在EDLC中的物理意义。

Modelling of Short-Term Memory Effect in Electric Double Layer Capacitor with Graphene-based Electrode
Electric double layer capacitor (EDLC) has seen widespread applications in energy storage for smooth operation of power systems. However, successful integration of EDLC into energy internet requires comprehensive understanding of its electrical response under various operation conditions. This work employs molecular dynamic simulations to study the physical mechanism behind the short-term memory effect reported in discharging process of EDLC. The physical meaning of constant phase element for EDLC is also revealed with equivalent circuit of transmission line model of resistors and capacitors.
