先进的2D材料作为追求改善储能性能的新范式引起了人们的极大兴趣。在此，锑烯首次被用作构建高度可变形和可编辑的独立膜电极的有效活性组分，作为具有创纪录电极性能的超级电容器的基础。锑烯的插入能够改善锑烯/MXene复合电极的环境稳定性，并显著提高在质子和中性电解质中的储能能力。值得注意的是，在1 m H2SO 4电解质中测试的电极实现了4255 F cm-3的比电容，这代表了迄今为止报道的基于MXene的超级电容器电极的最新技术水平。由复合电极构建的柔性超级电容器也表现出高度竞争性的能量和功率密度：非对称超级电容器为459.75 mWh cm−3和3.12 W cm−3，在中性电解质中具有2 V的更宽的电势窗口;对称配置为112.52 mWh cm−3和1 W cm−3，在酸性介质中具有1265 F cm−3的出色电容。这项工作为在不同电解质介质和各种设备配置中具有功能的高性能超级电容器电极的制造提供了新的思路。
Advanced 2D materials have spurred great interest as a new paradigm in pursuing improved energy storage performance. Herein, for the first time, antimonene is utilized as an effective active component for constructing highly deformable and editable freestanding film electrodes, as the basis of a supercapacitor with record‐breaking electrode performance. The insertion of antimonene is able to improve the environmental stability of the antimonene/MXene composite electrode and remarkably enhance the energy storage capability in both protic and neutral electrolytes. Notably, an ultrahigh specific volumetric capacitance of 4255 F cm−3 is achieved by the electrode tested in a1 m H2SO4 electrolyte, which represents the state‐of‐the‐art value reported to date for supercapacitor electrodes based on MXenes. The flexible supercapacitors constructed by the composite electrode, also demonstrate highly competitive energy and power densities: 459.75 mWh cm−3 and 3.12 W cm−3 for the asymmetrical one with a much widened potential window of 2 V in neutral electrolyte; 112.52 mWh cm−3 and 1 W cm−3 for the symmetrical configuration with an outstanding capacitance of 1265 F cm−3 in acidic media. This work sheds new light on the fabrication of high‐performance supercapacitor electrodes with functionalities in different electrolyte media and various device configurations.
