Electrode Width Utilization Calculator
Electrode width utilization affects active material yield, slitting efficiency, trim scrap, and cost per cell. This calculator helps process engineers compare usable coated width with available foil or web width against the utilization target.
What this calculator does
- Calculate electrode web width utilization from coated usable width, available foil width, and target utilization.
- a coating or slitting engineer needs to evaluate electrode layout, edge trim, and usable web width
- Returns the percentage of available electrode web width converted into usable coated width.
Formula used
- Electrode width utilization = usable coated electrode width รท available foil/web width
- Width utilization gap = target utilization - calculated utilization
Inputs explained
- Usable coated electrode width: Use width that can be slit into acceptable electrodes after edge trim and defects.
- Available foil/web width: Use incoming foil or coated web width on the same basis.
- Target width utilization: Use the layout, cost, or process target for the electrode design.
How to use the result
- Use it for coating layout, slitting plans, trim scrap reduction, and cost-per-cell improvement.
- It does not account for lengthwise defects, coating weight variation, or slitter yield unless those affect usable width.
Common questions
- Should edge trim be excluded? Yes. Use only the width that can become acceptable electrode strips.
- Can I use inches instead of mm? Yes, as long as usable and available widths use the same unit.
- Why does width utilization matter? Low utilization increases foil, coating, drying, and active material cost per usable electrode.
- How can I use the result? Use it to compare electrode layouts, trim strategies, and coating-width changes before locking the process standard.
