An operando calorimeter for high temperature electrochemical cells
David Young, Ariel Jackson, David Fork +4
Operando calorimetry has previously been utilized to study degradation, side reactions, and other electrochemical effects in electrochemical cells such as batteries at or near room…
Lithium Metal Penetration Induced by Electrodeposition through Solid Electrolytes: Example in Single-Crystal Li6La3ZrTaO12 Garnet
Tushar Swamy, Richard Park, Brian W. Sheldon +6
Solid electrolytes are considered a potentially enabling component in rechargeable batteries that use lithium metal as the negative electrode, and thereby can safely access higher…
Producing High Concentrations of Hydrogen in Palladium via Electrochemical Insertion from Aqueous and Solid Electrolytes
Jesse D. Benck, Ariel Jackson, David Young +2
Metal hydrides are critical materials in numerous technologies including hydrogen storage, gas separation, and electrocatalysis. Here, using Pd-H as a model metal hydride, we perfo…
Apparatus for Operando X-ray Diffraction of Fuel Electrodes in High Temperature Solid State Electrochemical Cells
Jesse D. Benck, Daniel Rettenwander, Ariel Jackson +2
Characterizing electrochemical energy conversion devices during operation is an important strategy for correlating device performance with the properties of cell materials under re…
Li-diffusion accelerates grain growth in intercalation electrodes: a phase-field study
Ananya Renuka Balakrishna, Yet-Ming Chiang, W. Craig Carter
Grain boundary migration is driven by the boundary's curvature and external loads such as temperature and stress. In intercalation electrodes an additional driving force results fr…
Modeling of internal mechanical failure of all-solid-state batteries during electrochemical cycling, and implications for battery design
Giovanna Bucci, Tushar Swamy, Yet-Ming Chiang +1
This is the first quantitative analysis of mechanical reliability of all-solid state batteries. Mechanical degradation of the solid electrolyte (SE) is caused by intercalation-indu…
