Title: Nanometer-scale electrochemical intercalation and diffusion mapping of Li-ion battery materials

Abstract

The electrochemical energy storage systems based on Li-based insertion and reconstitution chemistries are a vital component of future energy technologies. Development of high energy and power density materials demands detailed understanding of the nanoscale mechanisms involved in Li-battery operation, including the interplay between the interfacial electrochemical reactions, electron and Li-ion diffusion, and structural defects. We demonstrate that strong coupling between Li-ion concentration and lattice parameters can be used as an efficient basis for real-space imaging of Li-ion currents and electrochemical reactivity on the nanometer length scales, providing what until now has been an elusive view of the electrochemical reactivity on a level of single structural element.
