报告内容摘要：
Electrochemical Energy Storage and Conversion Systems are promising energy conversion ones for portable, automotive, and stationary power applications with high efficiency and minimal environmental impact. Although significant progress has been made in the past decades in terms of overall performance, power density, and cost reduction, their performance and associated degradation with use continues to be barriers that prevent its commercialization. Understanding their mechanisms is a critical area of study which has motivated many efforts to develop and apply advanced high-resolution techniques to characterize and quantify the state of various chemical species and components before, during, and after their operation. In this session, we will discuss several in-situ and ex-situ advanced diagnostic tools, which include: optical visualization, neutron imaging, electron spectroscopy and microscopy (SEM, TEM, and photoelectron spectroscopy), X-ray techniques, magnetic resonance imaging, and thermal mapping.

Dr. Zhang’s research has focused on development of high-efficiency, sustainable and clean energy systems with micro/nanotechnology, ranging from fundamental understanding to system development of fuel cells, batteries, high-efficiency pulse combustion engines, electrical thrusters, and hybrid energy systems. He has also established a strong expertise in the micro-/nano-scale design, fabrication, and characterization of thermal/fluid, surface, material, optical, and electrical properties, and in the development of advanced spectroscopy. Dr. Zhang has acquired extensive research and teaching experience at several institutions including UTK, Oak Ridge National Lab (ORNL), UD, PSU, UCLA, Stanford University, and Nagoya University. Dr. Zhang is the author of over 60 publications, 2 book chapters and 2 patents. Two of his publications earned the “most cited paper” recognition and one of them won the 1st place prize. He also served as Track Chair and Session Chair in International Conferences on Energy Sustainability and Technology, respectively.
