Public calculation provenance — checked 2026-10-20
Original AimatraLab teaching figure, not an experimental result. Python/matplotlib rendering.
Formula: LiFePO4. Electron transfer per formula unit: n=1 (explicit calculation assumption).
CIAAW 2024 abridged atomic weights: Li 6.94, Fe 55.845, P 30.974, O 15.999.

M=157.755000000000 g/mol. Q=nF/(3.6M)=169.893069281129 mAh/g.
The division by 3.6 converts C/g to mAh/g. Denominator: pure active-material mass.
Production calculations verified against vendor/tmccdb/src/lib/chemistry.ts and capacity.ts by tests.
lifepo4-mass.csv contains the elemental contributions used to generate the bar plot.
No empirical battery performance, uncertainty estimate, or reversible-electron inference is asserted.
