Prof. Jinghong Li is a Cheung Kong Professor at Department of Chemistry, Tsinghua University. He obtained his B.Sc. from University of Science and Technology of China in 1991, and Ph.D. from Changchun Institute of Applied Chemistry (CIAC), Chinese Academy of Sciences (CAS) in 1996. He then worked as postdoctoral researcher or research scientist at University of Illinois at Urbana-Champaign, University of California at Santa Barbara, Clemson University, and Evonyx Inc., USA (1997-2001). He was appointed as full professor at CIAC from May 2001 and Tsinghua University from July 2004. He served as associate editors for the following journals: Journal of Physics and Chemistry of Solids, and Science of Advanced Materials and many others. His current research interests include electroanalytical chemistry and bioanalysis, nanoanalysis and biosensing, physical electrochemistry and interfacial electrochemistry, material electrochemistry and nanoscopic electrochemistry, energy conversion and storage. He has published more than 250 papers in top journals including Nature Nanotech., J. Am. Chem. Soc., Adv. Mater., Anal. Chem., ACS Nano, Adv. Funct. Mater. and so on..


Electrochemistry combined with nanotechnology provides a promising strategy to solve the energy storage challenge. In electrochemical energy storage devices like lithium-ion batteries the optimization of electrode materials plays a vital role to improve device performance. In recent years, based on our understanding gained from the research on the kinetics and thermodynamics of lithium insertion and removal, we have constructed a series of high-capacity, high-cycle-stability lithium ion batteries through the fabrication of hierarchical nano-composite electrode materials, introduction of active substrates and so on. We also designed and fabricated functional electrodes based on semiconductor nanomaterials. Using the photo-electrochemical test station built in house, we studied the photo-electrochemical properties and the reaction mechanisms of our novel semiconductor nanomaterials, providing new insights for the design of high-sensitivity, simple and low-cost photo-electrochemical analysis.
