Emerging technologies, such as portable electronics, have had a huge impact on societal norms, such as access to real time information. To perform these tasks, portable electronic devices need more and more accessories for the processing and dispensation of the data, resulting in higher demand for energy and power. To overcome this problem, a low cost high-performing flexible fiber shaped asymmetric supercapacitor was fabricated, exploiting 3D-spinel manganese oxide MnO as cathode and 2D molybdenum disulfide MoS as anode. These asymmetric supercapacitors with stretched operating voltage window of 1.8 V exhibit high specific capacitance and energy density, good rate capability and cyclic stability after 3000 cycles, with a capacitance retention of more than 80%. This device has also shown an excellent bending stability at different bending conditions.
诸如便携式电子产品等新兴技术对社会规范产生了巨大影响，比如获取实时信息。为执行这些任务，便携式电子设备需要越来越多用于数据处理和分配的配件，从而导致对能源和电力的更高需求。为克服这一问题，利用三维尖晶石型氧化锰MnO作为阴极、二维二硫化钼MoS作为阳极，制备了一种低成本高性能的柔性纤维状非对称超级电容器。这些具有1.8V扩展工作电压窗口的非对称超级电容器表现出高比电容和能量密度、良好的倍率性能以及3000次循环后的循环稳定性，电容保持率超过80%。该器件在不同弯曲条件下也表现出优异的弯曲稳定性。
