Cathode Active Material & Precursor Manufacturing worked example

Calcination Energy with calcination kiln load of 6 kW: a worked example in cathode active material & precursor manufacturing

Suppose calcination kiln load falls to 6 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate kiln or furnace energy cost and energy cost per kg CAM for calcining precursor with lithium source into finished cathode powder.

The inputs for this scenario

  • Calcination kiln load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Kiln firing runtime: 8 hr (held at the documented default)
  • Energy price: 0.12 $ / kWh (held at the documented default)
  • Accepted CAM output: 1,000 kg CAM (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Calcination energy cost = calcination kiln load × kiln firing runtime × energy price.
  • Calcination energy cost works out to 5.76 $ at these inputs, and this is the headline figure for the scenario.
  • Calcination energy used works out to 48 kWh at these inputs.
  • Calcination energy cost per kg CAM works out to 0.01 $ / piece at these inputs.
  • Hourly calcination energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where calcination kiln load sits at 12 kW and the headline result is 11.52 $, this scenario comes in 50% below the baseline at 5.76 $.
  • It computes the total kiln energy cost for a fire and the energy cost per kilogram of accepted cathode active material. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
