Graphite, Anode & Battery Materials Processing worked example

Energy Intensity with battery-material process load of 1,100 kW: a worked example in graphite, anode & battery materials processing

What does the result look like when battery-material process load reaches 1,100 kW? The full calculation is worked below with real intermediate numbers. Use it when comparing process routes, furnace settings, dryer conditions, milling times, or production scale-up assumptions on a kWh-per-kg basis.

The inputs for this scenario

  • Battery-material process load: 1,100 kW (raised for this scenario; the documented default is 420)
  • Process energy runtime: 12 hr (unchanged)
  • Blended electricity rate: 0.11 $ / kWh (unchanged)
  • Processed anode material: 1,400 kg (unchanged)

Working through the calculation

  • Applying the documented formula (Process energy cost = battery-material process load × process energy runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 13,200 kWh for process energy used, the number this scenario is built around.
  • At this operating point the engine returns 1,452 $ for process energy cost.
  • At this operating point the engine returns 1.04 $ / piece for energy cost per kg.
  • At this operating point the engine returns 121 $ / hr for hourly process energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where battery-material process load sits at 420 kW and the headline result is 5,040 kWh, this scenario comes in 162% above the baseline at 13,200 kWh.
  • A figure at this level is achievable when battery-material process load is genuinely sustained, not just peaked for a shift. It assumes the process draws a constant load for the full runtime; real furnaces vary draw across heat-up, soak and cool, so a flat load can mislead.
