Battery Material Yield Loss Rate at 1.44% target maximum material loss: a worked example

Suppose target maximum material loss falls to 1.44%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate battery material yield loss from lost material, total material issued, and the target loss limit.

The inputs for this scenario

  • Lost battery material: 320 kg or units (held at the documented default)
  • Total material issued: 12,500 kg or units (held at the documented default)
  • Target maximum material loss: 1.44 % (the input this scenario stresses; the baseline uses 2)

Working through the calculation

  • The calculation starts from the formula this tool documents: Material loss rate = lost battery material รท total material issued.
  • Battery material loss rate works out to 2.56 % material loss at these inputs, and this is the headline figure for the scenario.
  • Material loss gap to limit works out to -1.12 points at these inputs.
  • Lost material works out to 320 kg or units at these inputs.
  • Material issued works out to 12,500 kg or units at these inputs.

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. 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.

Results at a glance

  • Battery material loss rate: 2.56 % material loss (headline result)
  • Material loss gap to limit: -1.12 points
  • Lost material: 320 kg or units
  • Material issued: 12,500 kg or units
