Tuqiang Chen, Ph. D.

Dr. Chen received his B.S. and M.S. degrees both in Fine Chem. Engineering from Beijing University of Aeronautics and Astronautics, Beijing, P. R. China in 1982 and 1987, respectively. He received his Ph. D. in Inorganic Chemistry from the University of New Mexico (UNM) in 1995. He joined TPL, Inc. in February 1998 after his postdoctoral research with Dr. R. T. Paine in the Chemistry Department of the University of New Mexico. After 9 years with TPL as principal investigator and program manager, he left TPL and founded TH Chem, Inc. in 2007. He has been serving as PIs in many US federal R&D programs, including NSF, NASA, DoE, and DoD SBIR/STTR programs. Most of the research projects are conducted in collaboration with Sandia National Laboratories (SNL), the University of New Mexico (UNM), and New Mexico Institute of Mining and Technology. His research areas include preparation and characterization of nanocomposites for Li-ion and supercapacitor applications, 3-D Li-ion batteries and supercapacitors, and solid polymer electrolyte (SPE) synthesis and characterizations.
The seminar will discuss recent advances in 3-dimensional Li-ion battery chemistry and technologies. It will include discussion of fundamental structural features of 3-D Li-ion batteries, the superior performance characteristics resulting from these unique structures, and challenges the technology faces. In particular, results from Dr. T. Chen’s team will be presented and discussed including preparation and characterization of ultrafine metal mesh (UMM) based Li-ion electrodes and 3-D devices. The synthesis and characterization of chemically labile Li imides, for solid polymer electrolyte (SPE) applications, will also be presented in the seminar. These labile imides can be readily grated to a flexible polymer backbone to form single-ion conducting polymers.
