Distinguished Lecture Series in Energy: Dr. Yi Cui

Dr. Yi Cui, the director of the Precourt Institute for Energy and the founding director of the Sustainability Accelerator at Stanford University, presents “Reinventing Batteries Through Nanoscience” as a part of the Distinguished Lecture Series in Energy on Wednesday, September 27, 2023.
Abstract
----------------
The fast growth of power sources for transportation and grid-scale stationary storage presents great opportunities for new battery chemistries. How to increase energy density, reduce cost, speed up charging, extend life, enhance safety, and reuse/recycle are critical challenges. Here I will present how we utilize nanoscience to reinvent batteries and address many challenges by understanding the materials and interfaces through new tools and providing design principles of new materials. The topics to be discussed include materials design to enable high-capacity materials: Si and Li metal anodes and S cathodes; materials for low-cost large-scale stationary energy storage; and a set of tools including cryogenic electron microscopy for understanding thermodynamic, kinetic, and structural information of battery chemistries.
