摘要
目前的工作重点是采用多种有机磷配体的有效方法,在膦酸锰中产生不同的形态。此外,该研究还深入探讨了各种结构体系结果的电化学性能。不同的有机配体产生了不同的形态,如层状、纳米片组装的花朵状、棒状和球状结构。对合成的微孔膦酸盐(MnBPA、MnPPA、MnDPA 和 MnNAPH)进行了全面的表征,这表明有机配体在混合框架中的结合是正确的。此外,还在 1V 的宽电压窗口内考察了碱性介质中的电化学性能。与其他制备的电极材料相比,MnBPA 具有规则的微孔性质和较大的表面积,有助于加快离子传输速度,其最大电容为 846 F g-1。使用最佳电极 MnBPA 作为阴极元件的不对称纽扣电池装置达到了惊人的能量密度(E.D.)156.6 Wh kg-1,功率密度(P.D.)1658 W kg-1。此外,在现代技术的推动下,利用一种廉价的真空过滤技术制造出了一种非对称平面间数字结构柔性微型超级电容器。战略性设计的数字间结构用作定制掩模,有效地减少了离子扩散路径,从而实现了 105.2 mF cm-2 的高面积电容。
Ligand-mediated manganese phosphonates with variable morphological framework: efficient for energy storage application
The current work focuses on the efficient method of employing multiple organophosphorus ligands to produce distinct morphological forms in manganese phosphonates. Also, it offers insight into the electrochemical performance to various structural architecture outcomes. Different morphologies, such as layered, nanosheet-assembled flower, rod, and sphere structures, have resulted from implementing distinct organic ligands. The as-synthesized microporous phosphonates (MnBPA, MnPPA, MnDPA, and MnNAPH) have been thoroughly characterized, which signifies the proper incorporation of the organic ligands in the hybrid framework. The electrochemical performance in an alkaline medium has also been examined in a wide voltage window of 1V. The regular microporous nature and large surface area, which facilitate faster ionic transport, display a maximum capacitance of 846 F g-1 for MnBPA compared to other as-prepared electrode materials. A striking energy density (E.D.) of 156.6 Wh kg-1 and a power density (P.D.) of 1658 W kg-1 was attained by an asymmetric coin cell device using the best electrode MnBPA as the cathode component. Furthermore, moving toward contemporary technology, an asymmetric in-plane interdigital structured flexible micro-supercapacitor was fabricated using an inexpensive vacuum filtration technique. The strategically designed interdigital structure, which was used as a customized mask, effectively reduces the ion-diffusion path, resulting in a high areal capacitance of 105.2 mF cm-2.
