On September 14, 2018, at the invitation of Prof. Zhang, Professor Zheng Chen from the University of Nottingham Ningbo China and Professor Lifeng Yan from the University of Science and Technology of China visited SINANO and gave academic reports.

      Professor Zheng Chen's report is entitled "Redox activated carbon nanotubes and energy storage". Since 2000, Professor Chen and his collaborators have carried out material preparation, electrochemical performance, and application in electrochemical energy storage devices, especially water-based supercapacitors and supercapattery batteries. ) In applied research. This report provides a summary introduction to carbon nanotube-conductive polymer composite materials and carbon nanotube-manganese dioxide composite materials, including the assembly and testing of laboratory-type supercapacitors, supercapacitor cells, and commercial prototype supercapacitors. And super capacitor pool technology in the application prospects of large-scale energy storage to make corresponding predictions. For more information, please refer to the review paper recently published by the author (Chen GZ, Supercapacitor and supercapattery as emerging electrochemical energy stores, Int. Mater. Rev., 62(4) (2017) 173–202.)

      Professor Yan's report is entitled "Preparation of 3D Graphene Functional Materials and Application in Energy Storage Devices". Two-dimensional and three-dimensional graphene-based materials have important application prospects in energy storage and conversion. Based on the construction of multi-dimensional graphene-based materials, Professor Yan’s team has developed a variety of new green preparation methods for graphene, and on this basis Through reduction and self-assembly method, the low-temperature and atmospheric preparation of three-dimensional graphene hydrogel/aerogel has been realized, and the preparation of three-dimensional graphene/nanoparticle composite materials that capture nanoparticles in situ has been developed, and the preparation of three-dimensional graphene/nanoparticle composites with in-situ nanoparticle capture The composite preparation of double-network conductive elastomer, and the related materials have shown superior performance in lithium-ion batteries, microbial fuel cells, supercapacitors, etc. At the same time, it has also developed a new manufacturing technology for self-supporting graphene ultra-thin films, obtained transparent and highly conductive graphene ultra-thin films, and used them in ultra-thin film capacitors and sensors with superior performance. At the same time, in view of the problem of ion channel retention in supercapacitors, an in-situ electrochemical reduction method was designed and realized, and the prepared three-dimensional graphene hydrogel achieved non-stacking charge and discharge performance, which was beneficial to improve its volume specific capacitance.
