Reinventing Batteries Through Materials Design and New Tools

How to increase battery energy density, reduce cost, speed up charging, extend life, enhance safety and reuse/recycle are critical challenges. Here I will present the 15 year research in my lab to address many of challenges by understanding the materials and interfaces through new tools and providing guiding principles for design. The topics to be discussed include: 1) A breakthrough tool of cryogenic electron microscopy, leading to atomic scale resolution of fragile battery materials and interfaces. 2) Materials design to enable high capacity materials: Si and Li metal anodes and S cathodes. 3) Lithium extraction from sea water and for battery recycling. 4) New battery chemistry for grid scale storage.
