Synthetic teaching example provenance — checked 2026-10-20 Original AimatraLab teaching scatter plot, not an experimental result. Python/matplotlib rendering. Input dataset: vendor/tmccdb/src/tools/rate-performance/data/rateExamples.ts, id rate-performance-example, isExample=true. Specific current (mA/g), specific capacity (mAh/g): 20,302; 50,296; 100,284; 250,252; 500,211; 1000,162. These are illustrative synthetic values, not extracted from a publication or a real customer sample. The input CSV contains only those two original columns and a visible synthetic-data comment. Normalisation: each R = specific current / its paired measured specific capacity, unit h^-1. 20/302=0.066225165563 h^-1; 1000/162=6.172839506173 h^-1. Convention source (not a source of these six synthetic points): Tian et al. (2019), Quantifying the factors limiting rate performance in battery electrodes, Nature Communications 10, 1933, Eq.4. https://www.nature.com/articles/s41467-019-09792-9 Live demonstration: https://aimatralab.com/lab/rate-performance/ The figure displays only points. It contains no fitted curve, fitted parameter claim or inferred transport mechanism.
