Supporting Data for Rapid Determination of Solid-State Diffusion Coefficients

Yu-Chuan Chien of Uppsala University provides the raw electrochemical and operando X-ray diffraction data supporting the publication "Rapid determination of solid-state diffusion coefficients by intermittent current interruption". The dataset includes experimental results comparing the Galvanostatic Intermittent Titration Technique (GITT) and Intermittent Current Interruption (ICI) methods for measuring Li-ion diffusion in LiNi0.8Mn0.1Co0.1O2 (NMC811) battery material. R scripts used for analysis and presentation are also included.

Use Cases

• Comparing diffusion coefficient measurement methods (GITT vs. ICI) based on the side-by-side experimental data
• Correlating Li-ion diffusion kinetics with structural changes based on the operando X-ray diffraction data
• Validating theoretical derivations from Fick's laws using the provided electrochemical experiment results
• Reproducing the analysis and visualizations from the associated manuscript using the included R scripts

Strengths

• Includes raw data from both electrochemical and operando X-ray diffraction experiments
• Provides analysis scripts written in R for reproducibility
• Data directly supports a peer-reviewed scientific publication

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and dataset size are unknown, which may limit suitability assessment
• Last update date is unknown; freshness unverified
