Cathode Active Material & Precursor Manufacturing calculator

Co-Precipitation Efficiency Calculator

Calculate how much dissolved metal feed reports to usable precursor solids instead of filtrate, wash water, off-spec material, or process loss. 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 how much dissolved metal feed reports to usable precursor solids instead of filtrate, wash water, off-spec material, or process loss.
  • Use it when co-precipitation efficiency in cathode active material and precursor manufacturing needs a clean rate and gap-to-target you can put on a tier board.
  • Turns metal recovered in precursor solids, metal fed to precipitation, target co-precipitation efficiency into a rate for co-precipitation efficiency in cathode active material and precursor manufacturing.

Formula used

  • Co-precipitation efficiency = metal recovered in precursor solids ÷ metal fed to precipitation × 100
  • Co-precipitation gap to target = target co-precipitation efficiency - co-precipitation efficiency

Inputs explained

  • Metal recovered in precursor solids: Enter nickel, manganese, cobalt, or total transition metal captured in accepted precursor solids.
  • Metal fed to precipitation: Use total contained metal from sulfate feed, recycle stream, or blend charge on the same basis.
  • Target co-precipitation efficiency: Use the process target for the chemistry, pH window, residence time, and solids content.

How to use the result

  • Use it when co-precipitation efficiency 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

  • What problem does this co-precipitation efficiency calculator solve? Calculate how much dissolved metal feed reports to usable precursor solids instead of filtrate, wash water, off-spec material, or process loss. You get a rate you can defend before quoting, scheduling, or sign-off.
  • Which inputs change the rate the most? metal recovered in precursor solids, metal fed to precipitation, target co-precipitation efficiency usually move the rate most. Pull from measured cathode active material and precursor manufacturing runs, supplier data, and recent quotes rather than memory.
  • How should I act on the output? Use the gap to target to prioritize the next cathode active material and precursor manufacturing kaizen or corrective action.
  • What should I double-check before acting? Confirm the counts came from the same time window and the same scope; mismatched scope is the most common error.
