Increasing requirements for wearable devices stimulate the development of flexible energy storage components. Herein, a flexible integrated electrode consisting of SnSnanosheet arraysanchored on the functionalized carbon cloth was prepared via a facile one-step hydrothermal method. Through pretreatment of carbon cloth, rough morphology is appeared on the surface of carbon fiber, which is conducive to optimizing the accessible load of SnS. The SnSnanosheet arrays and the carbon fiber as conductive skeleton cooperate with each other to provide a highly open surface, leading to the enhancement in capacitance (194.4 mF cm) and the outstanding retention after long-term service (86.5% after 10 000 cycles). A quasi-solid-state asymmetric flexible supercapacitor was assembled to evaluate the practical application under various conditions, suggesting satisfactory electrochemical performance as a maximum energy density of 10.95Wh cmat the power density of 4.75 mW cmand mechanical stability under actual conditions.
对可穿戴设备不断增长的需求刺激了柔性储能组件的发展。在此,通过简便的一步水热法制备了一种由锚定在功能化碳布上的SnS纳米片阵列组成的柔性集成电极。通过对碳布进行预处理,碳纤维表面出现粗糙形态,这有利于优化SnS的可及负载量。SnS纳米片阵列与作为导电骨架的碳纤维相互配合,提供了高度开放的表面,导致电容增强(194.4 mF/cm²)以及长期使用后的出色保持率(10000次循环后为86.5%)。组装了一种准固态不对称柔性超级电容器以评估其在各种条件下的实际应用,结果表明其具有令人满意的电化学性能,在功率密度为4.75 mW/cm²时最大能量密度为10.95 Wh/cm³,并且在实际条件下具有机械稳定性。
