In situ TEM studies of micron-sized all-solid-state fluoride ion batteries: Preparation, prospects, and challenges.

Abstract
Trustworthy preparation and contacting of micron-sized batteries is an essential task to enable reliable in situ TEM studies during electrochemical biasing. Some of the challenges and solutions for the preparation of all-solid-state batteries for in situ TEM electrochemical studies are discussed using an optimized focused ion beam (FIB) approach. In particular redeposition, resistivity, porosity of the electrodes/electrolyte and leakage current are addressed. Overcoming these challenges, an all-solid-state fluoride ion battery has been prepared as a model system for in situ TEM electrochemical biasing studies and first results on a Bi/La0.9Ba0.1F2.9 half-cell are presented. Microsc. (C) 2016 Wiley Periodicals, Inc.
