In situ TEM Studies of Micron-sized All-solid-state Fluoride Ion Batteries: Preparation, Prospects, and Challenges

2018-09-26 11:42:16 Keywords Fluoride Ion Battery, In situ TEM, Solid-state electrochemistry, Focused ion beam (FIB), All-solid-state-battery,
In situ TEM Studies of Micron-sized All-solid-state Fluoride Ion Batteries: Preparation, Prospects, and Challenges
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 ... Read more

Electrochemistry in Liquid Environments: Challenges in the Presence of Accelerated Electrons

2018-09-26 11:50:06 Keywords Beam damage, In situ TEM, Electrochemistry, Beam sensitivity,
Electrochemistry in Liquid Environments: Challenges in the Presence of Accelerated Electrons
A meticulous examination of transient stages of dynamic processes at the micrometer, nanometer or atomic scale is the aim in the field of in situ transmission electron microscopy. Studying a specimen in a state close to its native environment without drying possibly leading to structural alterations, triggers research in the field of in situ liquid TEM. However, for any in ...
