Supported by the National Natural Science Foundation of China, the research findings of Professor Sun Kening from HIT Institute of Basic and Interdisciplinary Science were published in the internationally famous journal – American Chemical Society•Nano ( ACS Nano, 2014 impact factor 12.881). The title of the research paper is “Pushing the Limits: 3D Layer-by-Layer-Assembled Composites for Cathodes with 160 C Discharge Rates”.
Professor Sun Kening innovatively uses the Layer-by-Layer-Assembled method for the preparation of 3D graphene, studying the cathode performance of lithium ion batteries by using this material as a conductive substrate and loaded with Lithium iron phosphate. Compared to the traditional physical and chemical vapour phase deposition, the Layer-by-Layer-Assembled method for the preparation of 3D graphene is of lower cost but more efficient, which is suitable for future large scale application. In this study, the cathode material of the lithium iron phosphate uses the high electrical conductivity and the high stability of 3D graphene realizing the release of the capacity of 56 mAh/g in 160C. This research was completed by HIT Institute of Basic and Interdisciplinary Science and the University of Michigan. Professor Sun Kening is the first corresponding author.
Professor Sun Kening is the specially invited professor of Changjiang Scholars. He is the director of HIT Institute of Basic and Interdisciplinary Science and Institute of Chemical and Energy Materials. He mainly carries out research on fuel cells, lithium ion batteries, super-capacitors and other research into electrochemical energy storage systems.
