论文摘要
多孔电极是下一代超级电容器的基本组件快速出现的。使用CO3O4，MN3O4，Alpha Fe2O3和碳的多孔结构，它们在固体对应物中的优势是明确确定的。多孔结构中的性能提高与增强的活动特异性表面和直接通道有关，从而导致与氧化还原活性位点的相互作用改善。提出了利用FICK定律的理论模型，可以始终如一地解释实验数据。由于较高的扩散系数，多孔结构在特定电容中表现出近50-80个百分比的增量，以及高速率能力和出色的循环稳定性。
Porous electrodes are fast emerging as essential components for next generation supercapacitors. Using porous structures of Co3O4, Mn3O4, alpha Fe2O3, and carbon, their advantages over the solid counterpart is unequivocally established. The improved performance in porous architecture is linked to the enhanced active specific surface and direct channels leading to improved electrolyte interaction with the redox active sites. A theoretical model utilizing the Fick's law is proposed, that can consistently explain the experimental data. The porous structures exhibit nearly 50 - 80 percentage increment in specific capacitance, along with high rate capabilities and excellent cycling stability due to the higher diffusion coefficients.
