Graphite, Anode & Battery Materials Processing worked example

Drying Energy Cost at 72% included drying cost share: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop included drying cost share to 72%, then walk the calculation through step by step. Estimate drying cost exposure for graphite, anode powder, slurry intermediates, or coated material using dried kg, energy cost per kg, included cost share, and fixed dryer setup cost.

The inputs for this scenario

  • Dried anode material mass: 1,200 kg (held at the documented default)
  • Drying energy cost per kg: 0.42 $ / kg (held at the documented default)
  • Included drying cost share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed dryer setup cost: 350 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable drying energy cost = dried anode material mass × drying energy cost per kg × included drying cost share.
  • Total drying energy cost works out to 713 $ at these inputs, and this is the headline figure for the scenario.
  • Drying energy cost per kg processed works out to 0.59 $ / piece at these inputs.
  • Variable drying energy cost works out to 363 $ at these inputs.
  • Fixed dryer setup cost works out to 350 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where included drying cost share sits at 100% and the headline result is 854 $, this scenario comes in 16.52% below the baseline at 713 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to included drying cost share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It treats energy cost per kg as flat, but real specific energy rises sharply for high-moisture or solvent-laden feeds, so a single rate can understate cost for wet material.
