ChemInform Abstract: In situ Observation of the Electrochemical Lithiation of a Single SnO₂ Nanowire Electrode.

Abstract

A nanoscale device consisting of a single SnO2 nanowire as an anode, an ionic liquid‐based electrolyte, and a LiCoO2 cathode inside a high‐resolution transmission electron microscope allows the in situ observation of the lithiation of the SnO2 nanowire during electrochemical charging.

Tracking the Diffusion-Controlled Lithiation Reaction of LiMn2O4 by In Situ TEM

“…A bias of -5V is applied between tip and sample to drive the reaction and counteract possible positive biases in the sample due to the secondary electron generation and the lithium oxide barrier. 20,21 The reaction could be halted by breaking off the contact between sample and tip.…”

Strain-Induced Corrosion Kinetics at Nanoscale Are Revealed in Liquid: Enabling Control of Corrosion Dynamics of Electrocatalysis

“…17 Understanding how corrosion proceeds in metal nanoparticle catalysts at the atomic scale requires monitoring the entire process with high resolution, which has only recently been possible. In situ liquid cell (LC) electron microscopy 18 can capture material evolution, [19][20][21] including growth, [22][23][24][25][26][27][28][29] phase transition, 30,31 diffusion, 32 and etching, [33][34][35][36] in real time.…”
