TL;DR: The spatial variation of lithium-ion diffusion times in the battery-cathode material LiCoO(2) is probed at a resolution of ∼100 nm by using an atomic force microscope to both redistribute lithium ions and measure the resulting cathode deformation, revealing that the diffusion coefficient increases for certain grain orientations and single-grain boundaries.

TL;DR: Electrochemical strain microscopy (ESM), which is a newly developed scanning probe microscopy based characterization method, utilizes the intrinsic link between bias-controlled Li-ion concentration and molar volume of electrode materials, providing the capability for studies on the sub-20 nm scale.

TL;DR: In this article, Li-CH═NR and Li-N═CR2 species, which are detrimental to anode properties, were formed by a reaction between the Li and the graphite-like C3N species.

TL;DR: A scanning probe microscopy approach to explore voltage-controlled ion dynamics in ionically conductive solids and decouple transport and local electrochemical reactivity on the nanometer scale is developed and a broad applicability of this method to other ionically conducting systems is predicted.

TL;DR: This work uses a recently developed liquid cell for in situ electrochemical transmission electron microscopy to obtain insight into the electrolyte decomposition mechanisms and kinetics in lithium-ion (Li-ion) batteries by characterizing the dynamics of solid electrolyte interphase (SEI) formation and evolution.
