Catch electrode variation before formation confirms it

In cell manufacturing the cost of a defect compounds: a coating deviation becomes a formation loss weeks later, after significant value has been added. The platform correlates upstream process data with downstream electrical results so drift is caught in the same run rather than in the yield report.

Where the cost sits

The problems we start from

These are the recurring findings from discovery workshops in this sector. If none of them describe your operation, a pilot is probably premature — and we will say so.

Operational problems

  • Yield loss is discovered after formation

    Electrical results arrive days or weeks after the process deviation that caused them, so the corrective action lands long after the affected material has moved on.

  • Upstream and downstream data never meet

    Coating, calendering, assembly and formation each keep their own records, making cross-stage correlation a manual data-science project.

  • Ramp-up hides systematic variation

    During ramp everything is moving at once, so it is genuinely difficult to separate a process problem from a recipe change or a material change.

  • Scrap value is high and rising

    Scrapping a formed cell destroys far more value than scrapping an electrode, yet detection usually happens at the expensive end.

Engineering constraints

  • Continuous and discrete processes in one chain

    Coating is continuous by length while assembly is discrete by cell, so genealogy has to bridge web position and cell identity.

  • Very high data rates

    Inline gauges produce thousands of readings per minute per lane, which has to be aggregated without losing the signal.

  • Recipe churn during ramp

    Limits and setpoints change frequently, so control limits must be versioned and analysis must respect the revision in force.

  • Multi-vendor equipment

    Lines combine Asian, European and in-house equipment with inconsistent interfaces and tag naming.

Platform capabilities

How the platform is configured for battery manufacturing

Same architecture, same modules — configured against the characteristics, sampling logic and evidence expectations of this sector.

Web-to-cell genealogy

Maps continuous coating position to discrete cell identity so a downstream failure can be traced to a specific lane and metre of electrode.

High-rate SPC

Streaming capability analysis per lane and per gauge with configurable subgroup logic for continuous processes.

Cross-stage correlation

Correlates coating, calendering and assembly parameters with formation and end-of-line electrical results to expose the real driver of yield loss.

Vision on electrode defects

Classifies pinholes, streaks, agglomerates and edge defects, tying each detection to web position and downstream cell.

Recipe and limit versioning

Every analysis respects the recipe revision in force at production time, which keeps ramp-phase data interpretable.

Expected ROI

A value case your controller can interrogate

Every line below is an assumption, not a promise. During a pilot each one is replaced with a measured figure from your own baseline, which is what makes the business case defensible in a capital review.

How we validate it

  • Baseline recorded before any change
  • Success criteria written into the pilot scope
  • Measured comparison in the pilot report
  • Exit conditions agreed up front

Illustrative model. Value is dominated by where in the process detection moves to, which is quantified during the pilot.
