Battery Material Yield Loss Rate at 2.3% target maximum material loss: a worked example

Push target maximum material loss up to 2.3% and the picture changes. This example computes every intermediate figure at that operating point. a battery plant needs to track expensive material loss during slurry, coating, cell assembly, or pack assembly

The inputs for this scenario

  • Lost battery material: 320 kg or units (unchanged)
  • Total material issued: 12,500 kg or units (unchanged)
  • Target maximum material loss: 2.3 % (raised for this scenario; the documented default is 2)

Working through the calculation

  • Applying the documented formula (Material loss rate = lost battery material รท total material issued) to the inputs above produces each figure below.
  • At this operating point the engine returns 2.56 % material loss for battery material loss rate, the number this scenario is built around.
  • At this operating point the engine returns -0.26 points for material loss gap to limit.
  • At this operating point the engine returns 320 kg or units for lost material.
  • At this operating point the engine returns 12,500 kg or units for material issued.

How this compares with the baseline

  • Against the tool's baseline example, where target maximum material loss sits at 2% and the headline result is 2.56 % material loss, this scenario lands almost exactly on the baseline at 2.56 % material loss.
  • It computes lost material as a percent of total material issued, plus the gap in points between that loss rate and your maximum-loss limit. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Battery material loss rate: 2.56 % material loss (headline result)
  • Material loss gap to limit: -0.26 points
  • Lost material: 320 kg or units
  • Material issued: 12,500 kg or units
