(Invited) Synchrotron-Based Characterization of Electrochemical Energy Storage Devices

Johanna Nelson Weker

Synchrotron-based X-ray characterization enables the non-destructive characterization of heterogeneous functional materials such as batteries, electrolyzers, and peudocapacitors. With in situ and operando X-ray scattering, spectroscopy, and microscopy techniques, we are sensitive to atomic-scale changes up through nanometer and micrometer morphology changes. Using …

Designing and mapping cascade catalysis pathway for balanced polysulfide conversion in Li-S batteries

Leyuan Zhang, Dongfang Cheng, Pu Zhang, David G. Hopkinson et autres

Abstract Lithium–sulfur batteries are fundamentally constrained by the sluggish 16-electron sulfur reduction reaction. Electrocatalytic sulfur reduction reaction is inherently complex, involving multiple lithium polysulfide intermediates (Li 2 S n , n = 2–8), each with distinct adsorption and activation requirements, leading to …

Boron‐Modified Silicon Carbonitride as a Sulfur Host for Stable Lithium–Sulfur Batteries

Murilo M. Amaral, Arijit Roy, Romil Bhandavat, Hudson Zanin et autres

Failure in lithium–sulfur batteries (LSBs) is largely attributed to the uncontrolled transport of soluble polysulfides. Therefore, an electrically conducting matrix that hosts elemental sulfur and prevents polysulfide dissolution into the electrolyte is highly desirable. Covalent ceramics prepared through a polymer pyrolysis route …

Michael J. Dzara, Samuel S. Welborn, Christopher Crain, Molleigh B. Preefer et autres

The operating lifetime of Ni-YSZ fuel electrodes used in solid oxide electrolysis cells and fuel cells (SOECs and SOFCs) is limited by Ni redistribution, one of the primary degradation mechanisms that must be overcome to extend the longevity and maximize the performance …
