How quickly can sodium-ion learn? Assessing scenarios for techno-economic competitiveness against lithium-ion batteries
Adrian Yao, Sally M. Benson, William C. Chueh
Sodium-ion batteries have garnered significant attention as a potentially low-cost alternative to lithium-ion batteries, which have experienced supply shortages and pricing volatil…
Interpretation of High-Dimensional Linear Regression: Effects of Nullspace and Regularization Demonstrated on Battery Data
Joachim Schaeffer, Eric Lenz, William C. Chueh +3
High-dimensional linear regression is important in many scientific fields. This article considers discrete measured data of underlying smooth latent processes, as is often obtained…
Correlative image learning of chemo-mechanics in phase-transforming solids
Haitao D. Deng, Hongbo Zhao, Norman L. Jin +14
Constitutive laws underlie most physical processes in nature. However, learning such equations in heterogeneous solids (e.g., due to phase separation) is challenging. One such rela…
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

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…
Theory of coupled ion-electron transfer kinetics
Dimitrios Fraggedakis, Michael McEldrew, Raymond B. Smith +6
The microscopic theory of chemical reactions is based on transition state theory, where atoms or ions transfer classically over an energy barrier, as electrons maintain their groun…
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,…
Electrochemical kinetics of SEI growth on carbon black, II: Modeling
Supratim Das, Peter M. Attia, William C. Chueh +1
Mathematical models of capacity fade can reduce the time and cost of lithium-ion battery development and deployment, and growth of the solid-electrolyte interphase (SEI) is a major…
