Cathode Active Material & Precursor Manufacturing worked example

Capacity Gap at 65% expected reactor and calciner uptime: a worked example in cathode active material & precursor manufacturing

This worked example runs the capacity gap numbers for a tougher week than the baseline: 65% expected reactor and calciner uptime instead of the typical 90%. Estimate usable CAM or precursor production capacity and identify the gap created by uptime and first-pass yield losses.

The inputs for this scenario

  • Rated CAM output per reactor cycle: 4 kg / cycle (held at the documented default)
  • Scheduled cycles in the period: 480 cycles (held at the documented default)
  • Expected reactor/calciner uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass quality yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross scheduled material capacity = rated output per production cycle × planned production cycles.
  • Usable CAM or precursor capacity works out to 1,211 kg at these inputs, and this is the headline figure for the scenario.
  • Gross scheduled material capacity works out to 1,920 kg at these inputs.
  • Capacity lost to uptime works out to 672 kg at these inputs.
  • Capacity lost to quality yield works out to 37.44 kg at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected reactor and calciner uptime sits at 90% and the headline result is 1,676 kg, this scenario comes in 27.78% below the baseline at 1,211 kg.
  • Use it for period capacity planning, customer volume commitments, and to decide whether to chase uptime or yield first. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Usable CAM or precursor capacity: 1,211 kg (headline result)
