Awesome! Hefei University of technology research and development of scalable super capacitors that can be repaired in real time

on April 15, it was learned from Hefei University of technology that the school of chemistry and chemical engineering of Hefei University of technology successfully developed a new type of super scalable capacitor through integrated device structure design in cooperation with Professor Huaiping's research team and Professor yushuhong's research team of University of science and technology of China. On April 15, it was learned from Hefei University of technology that the school of chemistry and chemical engineering of Hefei University of technology successfully developed a new super scalable capacitor through the integrated device configuration design from the research team of Professor Huaiping and the research team of Professor yushuhong of the University of science and technology of China, which achieved real-time self repair in the process of charging and discharging for the first time in the world, providing a new way for the research and development of intelligent flexible energy storage devices, and is expected to promote flexibility The development of wearable electronic devices

it is understood that the scalable supercapacitor has high mechanical flexibility and can maintain structural integrity and high conductivity during complex mechanical deformation such as bending and stretching. It can be used as an energy storage device for new wearable electronic devices and flexible bionic devices. The self repair performance is particularly important for the capacitor to automatically repair its structure and maintain its original conductivity and electrochemical performance when mechanical damage occurs. However, due to the lack of effective structural design and complete device configuration, the current scalable supercapacitor has limited mechanical deformation ability, and the dislocation between the capacitor electrode layer and the electrolyte layer is easy to occur, which seriously reduces the device capacity and stability, and seriously restricts the practical application of flexible supercapacitors

in response to this problem, the research team innovatively introduced dynamic metal coordination bonds in the monomer initiated polymerization process, and successfully developed nanocomposite hydrogel electrodes and electrolytes with excellent flexibility and optical and electrical multiple stimulus response repair properties. By further chemically welding Silver Nanowire Films on gel electrodes as fluid collectors, the team realized the use of rich metal sulfur coordination between layers, chemical bonding to build supercapacitors with an overall configuration

supercapacitors show excellent tensile elasticity

research has proved that based on the microstructure and interface force optimization of each group of capacitors and the integrated device configuration design, it is particularly suitable for the production line and laboratory to control the product quality. This new supercapacitor has excellent flexibility and repairable supercapacitor performance. The experimental results show that the surface capacitance of this new capacitor is as high as 885 mf/cm2, and the tensile strain is up to 8 times the length of the original oil delivery valve. At the same time, based on the excellent intrinsic elasticity and self-healing performance of electrodes and electrolytes and the integrated device configuration design, the capacitor has fast optical self-healing ability and efficient electrical real-time self-healing ability
