New generation of battery materials are accompanied by large volume and structure change and instability of interphase. Nanoscale materials design represents a new powerful paradigm shift and offers new solutions to address these challenges. Here I will present our recent progress on: 1) Nanoscale design of host and interface for Li metal anodes; 2) Discovery of sulfur cathode phase behavior, leading to new guidance to materials design; 3) The first successful example of cryogenic electron microcopy applied to battery materials research, leading atomic scale resolution of Li metal dendrite and solid electrolyte interphase.
