Multimodal and In-Situ Chemical Imaging of Critical Surfaces and Interfaces in Li Batteries

Abstract

This article describes ways that a range of microscopy, spectroscopy, and spectrometry tools are being used to address important challenges associated with energy storage science and technology, in particular the development of advanced batteries for transportation, consumer use, and renewable storage. In this article in situ transmission electron microscopy, in situ secondary ion mass spectrometry, and XPS have been used to examine the formation and properties of the solid-electrolyte interphase (SEI) layer. Also TEM, atom probe tomography (APT), and nanoSIMS have been used to optimize the structure and processing of a lithium transition metal oxide cathode.
