Title: Electrical Energy Storage: Near-term and Long-term Perspectives
Rapid increase in global energy use and growing environmental concerns have prompted the development of clean, sustainable, alternative energy technologies. Renewable energy sources like solar and wind are a promising solution, but electrical energy storage (EES) is critical to efficiently utilize electricity produced from renewable sources as they are intermittent. EES is also the only viable near-term option for electrification of the transportation sector. Rechargeable batteries are prime candidates for EES, but their widespread adoption for electric vehicles and grid electricity storage requires optimization of cost, cycle life, safety, energy density, power density, and environmental impact, all of which are directly linked to severe materials challenges. Lithium-ion batteries have aided the revolution in portable electronics for more than two decades, but the necessity of large batteries for electric vehicles and grid storage prompts the development of next-generation of low-cost battery chemistries. After providing a brief account of the current status, this presentation will focus on the development of advanced materials and new battery chemistries for near-term and long-term battery technologies. Particularly, the challenges and approaches of transitioning from the current insertion-compound electrodes in lithium-ion batteries to new conversion-reaction electrodes with multi-electron transfer to increase the energy density and lower the cost will be presented. Specifically, lithium-based batteries based on low-cobalt oxide and sulfur cathodes and interdigitated alloy anodes will be presented. The challenges of bulk and surface instability and chemical crossover during charge-discharge cycling, advanced characterization methodologies to develop an in-depth understanding, and approaches to overcome the challenges will be presented.
Arumugam Manthiram is currently the Cockrell Family Regents Chair in Engineering and Director of the Texas Materials Institute and the Materials Science and Engineering Program at the University of Texas at Austin (UT-Austin). He received his Ph.D. degree in chemistry from the Indian Institute of Technology Madras in 1981. After working as a postdoctoral researcher at the University of Oxford and at UT-Austin with Professor John Goodenough, he became a faculty member in the Department of Mechanical Engineering at UT-Austin in 1991. Dr. Manthiram’s research is focused on clean energy technologies: rechargeable batteries, fuel cells, and supercapacitors. He has authored more than 760 journal articles with 55,000 citations and an h-index of 117. He directs a large research group with about 30 graduate students and postdoctoral fellows. He has provided research training to more than 200 students and postdoctoral fellows, including the graduation of 58 Ph.D. students and 26 M.S. students. He is the Regional (USA) Editor of Solid State Ionics, Co-Editor of Ceramics in Modern Technologies, and an Associate Editor of Energy and Environmental Materials.
Dr. Manthiram is a Fellow of six professional societies: Materials Research Society, Electrochemical Society, American Ceramic Society, Royal Society of Chemistry, American Association for the Advancement of Science, and World Academy of Materials and Manufacturing Engineering. He received the university-wide (one per year) Outstanding Graduate Teaching Award in 2012, the Battery Division Research Award from the Electrochemical Society in 2014, the Distinguished Alumnus Award of the Indian Institute of Technology Madras in 2015, the Billy and Claude R. Hocott Distinguished Centennial Engineering Research Award in 2016, and the Da Vinci Award in 2017. He is a Web of Science Highly Cited Researcher in 2017 and 2018.
