Recently, with our university as the first signatory unit, Prof. Gao Jihui's team, Prof. Sun Fei, was the first author's title entitled 'In-situ high-content nitrogen-doped carbon nanospheres enhance the storage activity of positive and negative polarizers to build 4.5 V high energy. The research paper on density all-carbon lithium-ion capacitors' was published in Nanometer Express, a well-known publication in the nanometer field. Lithium-ion capacitors (LICs) combine the features of lithium-ion batteries and supercapacitors, promising good power density, energy density and circulation Life expectancy, with great application prospects.
In order to solve the problem of charge transfer kinetics and life matching between two electrodes, Gao Jihui's team obtained a high concentration of nitrogen-doped carbon nanoballs based on continuous aerosol-assisted spray synthesizing technology, and also used as a positive and negative electrode material for lithium ion capacitors. Effectively resolves the electrochemical contradiction between the negative electrode storage lithium ion (Li+) and the positive electrode storage hexafluorophosphate (PF6-), demonstrating the development potential and application prospects of high-voltage all-carbon symmetrical lithium ion capacitors, and at the same time through the regulation of carbon nanomaterials Chemical environment to design high-performance lithium-ion capacitors provide ideas.
Sun Fei followed Gao Jihui from the second grade to develop carbon-based functional materials and research on the removal of pollutants. During his Ph.D., he went to the research group of Professor LV Yunfeng of the University of California, Los Angeles to jointly cultivate and gradually expand the carbon-based electrochemical storage. Energetic research was selected in July 2017 through the appointment of associate professor Yang Jiaojian of the university. In the past two years, the carbon-based materials have been controlled by the chemical environment, the controlled preparation of coal-based carbon materials and their electrochemical energy storage, gas molecular adsorption, and the recycling of pollutants. The application of removal has carried out more in-depth research. Related research has been published in “Nano Research”, “Advanced Energy Materials”, “Material Chemistry A”, “Science Report”, “Power Supply”, “Carbon Materials” and “Chemical Engineering”, etc. Hot papers and ESI high cited papers.
Gao Jihui's team has been conducting research on energy cleansing conversion and utilization since 2006. At present, 'carbon-based functional materials that integrate energy storage and pollutant control' 'enhanced calcium-based/carbon-based materials for solar thermal conversion use', ' "Low-level coal steps, high-value transformation and utilization," and "quantum chemistry and molecular dynamics calculations involving energy conversion and utilization processes" have been studied. In the past five years, we have undertaken major projects including the National Natural Science Foundation of China, projects, and youth fund projects. The National Natural Science Foundation of China has a total of 8 projects. Based on the research foundation for the removal of coal-based active coke pollutants, in 2017, the team and Shenhua Group, Shandong University, etc. jointly obtained 'sulfur recovery from coal-fired flue gas. And in the utilization of resources and technology' national key research and development special support; in 2018, the team and Zhejiang University, Huazhong University of Science and Technology, etc. jointly obtained the national key research and development support for the 'coal process organic pollutant emission control technology'.
