Abstract

In this work, a supercapacitor device with a graphene/hexagonal boron nitride (hBN) electrode and KCl electrolyte was simulated to investigate its electrochemical performance. Key parameters such as potential and current of the cell, ion concentration (\(\hbox {K}^+\) and \(\hbox {Cl}^-\)), electrode and electrolyte potential, and total current density at the interface were analyzed over time. The electrode current density as a function of electrode potential was also studied. The results demonstrated a maximum specific capacitance of 624.72 F/g at a current density of \(-\hbox {1.08 A/cm}^2\) and a potential of 0.116 V, confirming the system’s behavior within the supercapacitor range. Additionally, the maximum power dissipation density was 54.13 \(\hbox {W/cm}^3\) at a current density of −0.61 \(\times\) \(\hbox {10}^{-4}\) \(\hbox {A/cm}^2\). These findings highlight the potential of KCl as an effective electrolyte in graphene/hBN-based supercapacitors, paving the way for enhanced energy storage technologies.

以石墨烯/氢化硼为电极材料，以氯化钾为电解液的超级电容器装置及其性能模拟

在这项工作中，模拟了一种具有石墨烯/六方氮化硼（hBN）电极和KCl电解质的超级电容器器件，以研究其电化学性能。随着时间的推移，对电池的电位和电流、离子浓度（\(\hbox {K}^+\)和\(\hbox {Cl}^-\)）、电极和电解质电位以及界面总电流密度等关键参数进行了分析。研究了电极电流密度随电极电位的变化规律。结果表明，当电流密度为\(-\hbox {1.08 A/cm}^2\)，电势为0.116 V时，该系统的最大比电容为624.72 F/g，证实了该系统在超级电容器范围内的性能。当电流密度为−0.61 \(\times\)\(\hbox {10}^{-4}\)\(\hbox {A/cm}^2\)时，最大功耗密度为54.13 \(\hbox {W/cm}^3\)。这些发现突出了KCl作为石墨烯/ hbn基超级电容器中有效电解质的潜力，为增强储能技术铺平了道路。

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
