Cathode Active Material & Precursor Manufacturing worked example

Particle Size Distribution Yield at 99% target psd yield: a worked example

This scenario runs the particle size distribution yield calculation on the strong side: 99% target psd yield, with every other input held at its documented default. Use it when particle size distribution 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

  • Powder within PSD specification: 8 kg (unchanged)
  • Total powder classified or sampled: 250 kg (unchanged)
  • Target PSD yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Particle-size distribution yield = powder within PSD specification ÷ total powder classified or sampled × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for particle-size distribution yield, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for psd yield gap to target.
  • At this operating point the engine returns 8 count for powder within psd specification.
  • At this operating point the engine returns 250 count for total powder classified or sampled.

How this compares with the baseline

  • Against the tool's baseline example, where target psd yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it after classification, milling, or co-precipitation when you have weighed the in-spec fraction against the total mass sampled or classified. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Particle-size distribution yield: 3.2 % (headline result)
