使用地球丰富材料的水性超级电容器的抑制自放电
Suppressed self-discharge of an aqueous supercapacitor using Earth-abundant materials
摘要：
超级电容器（也称为静电双层电容器-EDLC）提供优异的功率存储容量和动力学，但遭受快速自放电。我们将沸石骨架引入到活性电容器电极中，目标是定制自由脱附能，从而定制超级电容器的自放电速率。使用低成本碳质材料和台式生产方法来制造超级电容器电极，其具有17.25 F g $^{-1}$的测量比电容、100%的库仑效率和通过恒电流充电/放电曲线测量确定的24小时内超过25%的电荷保持率。与没有沸石涂层的电极相比，该电荷保持率提高了$\sim$ 350%。
英文摘要：
Supercapacitors (aka electrostatic double-layer capacitors -- EDLCs) offer excellent power storage capacity and kinetics, but suffer under rapid self-discharge. We introduced a zeolite framework into the active capacitor electrode, with the goal to tailor the free desorption energy and thus the self-discharge rate of supercapacitors. Low-cost carbonaceous materials and benchtop production methods were used to create supercapacitor electrodes with a measured specific capacitance of 17.25 F g$^{-1}$, a coulombic efficiency of 100%, and charge retention of over 25% over 24 hours determined by galvanostatic charge/discharge curve measurements. This charge retention was an enhancement of $\sim$350% compared with electrodes without zeolite coating.
