摘要
以便增加电极表面区域并且提高费用存储能力,我们学习微电镀物品制作三维的高方面比率的机械系统技术微电极的结构基于玻璃。阳极的经常的潜在的方法被采用在微电极的表面上作为 electroactive 物质扔锰氧化物。周期的 voltammetry 和经常的当前的费用分泌物方法两个都被用来电气化学的性能测试准备电极,与没有为比较的结构的一个二维的电极。试验性的结果证明那三维的电极结构能有效地提高费用存储能力。在 1.0 mA/cm2 费用分泌物密度,三维的电极显示出 17.88 mF/cm2 的一个电容,比二维的电极高七倍。
In order to increase the electrode surface area and enhance the charge storage capacity, we study the micro electro mechanical system technology to fabricate three-dimensional high aspect ratio micro-electrode structure based on glass. The anodic constant potential method is employed to deposit manganese oxide as electroactive substances on the micro-electrode surface. Cyclic voltammetry and constant current charge-discharge method are both used to prepare electrode electrochemical performance testing, with a two-dimensional electrode without structure for comparison. Experimental results show that three-dimensional elec- trode structure can effectively enhance the charge storage capacity. At 1.0 mA/cm2 charge- discharge density, the three-dimensional electrode shows a capacitance of 17.88 mF/cm2, seven times higher than the two-dimensional electrode.
