Correlative analysis of structure and chemistry of LixFePO4 platelets using 4D-STEM and X-ray ptychography
L. A. Hughes, Benjamin H. Savitzky, Haitao D. Deng +9
Lithium iron phosphate (LixFePO4), a cathode material used in rechargeable Li-ion batteries, phase separates upon de/lithiation under equilibrium. The interfacial structure and che…
Layer-Resolved Many-Electron Interactions in Delafossite PdCoO2 from Standing-Wave Photoemission Spectroscopy
Qiyang Lu, Henrique Martins, J. Matthias Kahk +7
When a three-dimensional material is constructed by stacking different two-dimensional layers into an ordered structure, new and unique physical properties can emerge. An example i…
Universal phase dynamics in VO2 switches revealed by ultrafast operando diffraction
Aditya Sood, Xiaozhe Shen, Yin Shi +9
Strongly correlated materials that exhibit an insulator-metal transition are key candidates in the search for new computing platforms. Understanding the pathways and timescales und…
Electrochemical Ion Insertion: From Atoms to Devices
Aditya Sood, Andrey D. Poletayev, Daniel A. Cogswell +7
Electrochemical ion insertion involves coupled ion-electron transfer reactions, transport of guest species, and redox of the host. The hosts are typically anisotropic solids with t…
Coulombically-stabilized oxygen hole polarons enable fully reversible oxygen redox
Iwnetim I. Abate, C. Das Pemmaraju, Se Young Kim +10
Stabilizing high-valent redox couples and exotic electronic states necessitate an understanding of the stabilization mechanism. In oxides, whether they are being considered for ene…
Electrochemical kinetics of SEI growth on carbon black, I: Experiments
Peter M. Attia, Supratim Das, Stephen J. Harris +2
Growth of the solid electrolyte interphase (SEI) is a primary driver of capacity fade in lithium-ion batteries. Despite its importance to this device and intense research interest,…
