Cathode Active Material & Precursor Manufacturing calculator

Precursor Yield Calculator

Calculate precursor yield from recovered precursor mass versus theoretical or charged metal-equivalent mass for a co-precipitation batch or campaign. Two counts and a target give you a rate plus how far you are from where you need to be.

What this calculator does

  • Calculate precursor yield from recovered precursor mass versus theoretical or charged metal-equivalent mass for a co-precipitation batch or campaign.
  • 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.
  • Turns recovered precursor mass, theoretical precursor mass, target precursor yield into a rate for precursor yield in cathode active material and precursor manufacturing.

Formula used

  • Precursor yield = recovered precursor mass ÷ theoretical precursor mass × 100
  • Precursor yield gap to target = target precursor yield - precursor yield

Inputs explained

  • Recovered precursor mass: Enter dry precursor hydroxide or carbonate mass that passed filtration, washing, drying, and in-process release.
  • Theoretical precursor mass: Use recipe stoichiometry or metal feed charged to the reactor converted to the same precursor mass basis.
  • Target precursor yield: Use the co-precipitation yield target or minimum acceptable batch yield for this chemistry and campaign.

How to use the result

  • Use it when precursor yield in cathode active material and precursor manufacturing is being reviewed against a KPI.
  • Trend matters more than a single snapshot; pull the result for the last several periods before you act.

Common questions

  • Why use this precursor yield tool for cathode active material and precursor manufacturing? Calculate precursor yield from recovered precursor mass versus theoretical or charged metal-equivalent mass for a co-precipitation batch or campaign. You get a rate you can defend before quoting, scheduling, or sign-off.
  • Which assumptions drive the rate? recovered precursor mass, theoretical precursor mass, target precursor yield usually move the rate most. Pull from measured cathode active material and precursor manufacturing runs, supplier data, and recent quotes rather than memory.
  • What do I do with this number? Use the gap to target to prioritize the next cathode active material and precursor manufacturing kaizen or corrective action.
  • What should I verify first? Confirm the counts came from the same time window and the same scope; mismatched scope is the most common error.
