摘要
为实现具有成本效益的电源,人们对天然资源进行了深入研究,而生物质资源则是其中的佼佼者。在这项研究中,利用磷酸(H3PO4)对香蕉皮进行了化学活化,从而开发出一种高性能锌离子混合超级电容器(ZIHSC)。化学活化 BP-H3PO4 材料的 SEM(扫描电子显微镜)形态显示出一种纳米多孔结构,BET(布鲁纳-艾美特-泰勒)进一步证实了香蕉皮生物炭表面积的增加(218.339 m2 g-1)。由于生物质很容易转化为生物炭和活性生物炭,因此该工艺的合成成本很低。经磷酸(H3PO4)处理的香蕉皮用于 ZIHSC 设备,显示出 228 F g-1 的出色比电容(扫描速率为 1 mV s-1)、120 Wh Kg-1 的能量密度和 73.98 mAh g-1 的比容量(电流密度为 0.1 A g-1)。基于世伟洛克的双电极 ZIHSC 电池在经过 50,000 次充放电循环后仍能保持惊人的容量。
Synthesis of high surface area activated carbon from banana peels biomass for zinc-ion hybrid super-capacitor
The race to achieve cost-effective power sources has led to intense research to explore natural sources, and biomass sources are the front-runners. In this work, the chemical activation of the banana peel was carried out using phosphoric acid (H3PO4) to develop a high-performance zinc-ion hybrid super-capacitor (ZIHSC). SEM (Scanning Electron Microscopy) morphology of chemically activated BP-H3PO4 materials revealed a nano-porous structure, and BET (Brunauer-Emmett-Teller) further corroborates the enhancement in surface area (218.339 m2 g−1) of banana peel biochar. The process yields a low synthesis cost due to the facile conversion of biomass to biochar and activated biochar. The phosphoric acid (H3PO4) treated banana peel for the ZIHSC device showed an excellent specific capacitance of 228 F g−1 (1 mV s−1, scan rate), an energy density of 120 Wh Kg−1, and a specific capacity of 73.98 mAh g−1 (0.1 A g−1, current density). The two-electrode Swagelok-based ZIHSC cell retains incredible capacity retention after 50,000 charge and discharge cycles.
