Abstract

Rechargeable batteries represent a promising energy storage technology that can serve at various energy scales: they can be used to improve the stability and reliability of electric grid and to promote the utilization of renewable energy sources (solar, wind, etc.); they can also be used to power up a wide range of mobile devices from cell phones to electric vehicles. The development of high performance batteries relies on the improvement of materials, electrodes, electrolytes, separators, etc. In this presentation, two approaches to develop high performance battery materials will be presented. First, Materials Genome project will be introduced, which is a new approach that combines high-throughput computational and experimental efforts to design new materials. Second, a few examples will be shown to demonstrate another approach that combines novel synthesis method and advanced in situ characterization methods (e.g. synchrotron X-ray diffraction, solid state nuclear magnetic resonance, electron microscopy) to improve the performance of battery materials. These advanced in situ methods can also be used in other energy technologies and other fields such as biomedical, environmental, and MEMS research.


Biography

Dr. Hailong Chen is currently a Postdoctoral Associate at the Department of Materials Science and Engineering at Massachusetts Institute of Technology, working with Prof. Gerbrand Ceder. His research interests include the development of new devices for energy conversion and storage, as well as the application of advanced in situ characterization methods in energy research area. Hailong’s current research at MIT focuses on the Materials Genome project, a novel approach to design and synthesize new functional materials through combined computational and experimental approach. Hailong received his BS degree in materials science and engineering and MS in chemistry from Tshinghua University, China. He received his PhD in chemistry at the State University of New York - Stony Brook with Prof. Clare Grey. His PhD research focused on the synthesis of nano materials and the use of advanced in situ characterization techniques (e.g., synchrotron X-ray diffraction, solid state nuclear magnetic resonance spectroscopy, and electron microscopy) to study the microstructure and the functioning mechanism of nano materials in energy devices.
