Cathode Active Material & Precursor Manufacturing worked example

Precursor Yield at 99% target precursor yield: a worked example

What does the result look like when target precursor yield reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when precursor yield in cathode active material and precursor manufacturing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Recovered precursor mass: 8 kg (unchanged)
  • Theoretical precursor mass from feed: 250 kg (unchanged)
  • Target precursor yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Precursor yield = recovered precursor mass ÷ theoretical precursor mass × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for precursor yield, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for precursor yield gap to target.
  • At this operating point the engine returns 8 count for recovered precursor mass.
  • At this operating point the engine returns 250 count for theoretical precursor mass.

How this compares with the baseline

  • Against the tool's baseline example, where target precursor yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target precursor yield is genuinely sustained, not just peaked for a shift. It is a mass-recovery ratio only; it does not assess precursor quality attributes like tap density, particle size distribution, or metal stoichiometry, which can pass on yield yet fail spec.
