报告摘要/Abstract

Energy storage is the key to integrating renewable resources into the power grid and to deploying electric vehicles in the near future. Advanced nanostructured materials are needed to improve the performance and reduce the cost of different energy storage systems. For example, lithium-ion batteries are the current choice for electric vehicles, but face many challenges, such as energy density, charge rate, and safety. Atomic layer deposition (ALD) is a powerful nanofabrication technique capable of depositing highly uniform and conformal film coatings on any dimensional substrates for a variety of applications. This talk will discuss the use of ALD to develop key energy materials, including electrode materials, solid-state electrolytes, and surface coating materials, and their applications in developing high-performance lithium-ion batteries. Moreover, the presentation will also introduce the recent progress in the development of next-generation batteries, sodium-ion batteries and lithium-sulfur batteries, which exhibit high energy and power density and extremely low cost. These new battery systems are very promising alternatives to lithium-ion batteries for both transportation and electricity grid. Furthermore, the talk will also cover the applications of advanced characterization techniques, such as synchrotron radiation, in- situ high-temperature X-ray diffraction, high-resolution transmission electron microscope, in analyzing the structure of energy materials and understanding reaction mechanisms in battery systems. Outlook for the key challenges and great opportunities in next-generation energy storage systems will be presented in the end.

 

作者简介/Speaker’s short biography

Dr.Jian Liu is an Assistant Professor in School of Engineering atthe University of British Columbia (UBC) Okanagan campus (Kelowna, BC, Canada). Dr. Liu received his Master’s degree in the State Key Laboratory for Advanced Metals and Materialsat University of Science and Technology Beijing in 2009, and his Ph.D. at University of Western Ontario (London, ON, Canada) in 2013. Prior to joining UBC in January 2017, Dr. Liuworked as a Postdoctoral Fellow at Lawrence Berkeley National Laboratory (LBNL) and Pacific Northwest National Laboratory (PNNL). His current research focus on advanced nanofabrication techniques (atomic layer deposition, chemical vapor deposition), materials design for Li-ion batteries and beyond, and interfacial control and phenomena understanding in energy storage systems. Dr. Liu has published 52 high-quality papers with over 2300 citations and an H-index of 23. He is the recipient of severalprestigious awards and scholarships, including Chinese Government Award for Outstanding Self-Financed Students Abroad (2013), Natural Sciences and Engineering Research Council of Canada (NSERC) Postdoctoral Fellowship Award (2014-2016), Mitacs Elevate Postdoctoral Fellowship Award (2013-2014), and PNNL Alternated-Sponsored Fellowship (2015-2016).
