In the past two decades rechargeable batteries have been a great success in powering consumer electronics. There is a recent strong interest in applying rechargeable batteries to vehicle electrification and grid-scale storage, which present new challenges and opportunities for batteries including energy density, cost, safety, cycle life among many parameters. This talk reviews existing technologies and looks into next generation of batteries with great promise for vehicles and grids. Particularly, novel battery materials are key for a revolutionary change. High-energy batteries examples include silicon and lithium metal anodes, and sulfur and air cathodes. Novel aqueous and redox-flow batteries with low cost could impact the grid-scale storage. Smart separators could enhance the battery safety significantly.
Yi Cui is an Associate Professor and a David Filo and Jerry Yang Faculty Scholar in the Department of Materials Science and Engineering and Department of Chemistry (courtesy) at Stanford University, and a joint faculty in SLAC National Accelerator Laboratory. He has BS from the University of Science and Technology of China (1998), Ph.D from Harvard University (2002) and was Miller Postdoctoral Fellow at the University of California, Berkeley. In 2005 he joined in Stanford as an Assistant Professor. In 2010 he was promoted to an Associate Professor with tenure. His current research is on nanomaterials for energy storage, solar cells, water, topological insulators and biology. He is an Associate Editor of a top nanotechnology journal Nano Letters. He is a co-director of the Bay Area Photovoltaics Consortium, which is funded with $25M by the US Department of Energy. He has founded Amprius Inc., a company to commercialize high-energy battery technology from his research group.
