Abstract：
In this work, we reported the electrochemical performance of a type of carbon fabric-based supercapacitor by coating MnOx@rGO nanohybrids on carbon fabric with a simple one-step hydrothermal method. We studied the mass ratio of MnOx to rGO on the electrochemical properties of the carbon fabric-based supercapacitors. We found that as the mass ratio is 0.8:1 for MnO@rGO, the supercapacitor with a loading of 5.40 mg cm-2 of MnO@rGO nanohybrids on carbon fabric exhibits a specific capacitance of 831.25 mF cm-2 at 0.1 mA cm-2 current density. It also shows long-term cycling capacitance retention of 97.2% after 10,000 charge-discharge cycles at a current density of 0.4 mA cm-2. We speculate that the high electrochemical performance results from the strong interfacial bonding between the hierarchical architecture of MnO@rGO nanohybrids and carbon fabric.
摘要：
在这项工作中,我们报道了一种基于碳织物的超级电容器的电化学性能，通过简单的一步水热法将MnOx@rGO纳米杂化物涂覆在碳织物上。研究了MnOx与rGO的质量比对碳纤维织物基超级电容器电化学性能的影响。我们发现MnO@rGO的质量比为0.8:1，在碳织物上负载为5.40mgcm-2的MnO@rGO纳米杂化物的超级电容器在0.1mAcm-2电流密度下的比电容为831.25mFcm-2。在0.4mAcm-2的电流密度下，经过10,000次充放电循环后，它还显示出97.2％的长期循环电容保持率。我们推测，高电化学性能是由于MnO@rGO纳米杂化物的分层结构与碳织物之间的强界面结合所致。
