Battery electrode coating defects
Detect pinholes, agglomerates, streaks, and uncoated patches on electrode coatings.
Example outputs shown for illustration. Numbers depend on your samples and protocol.
Results
Each measurement below comes from your own images, tied back to the annotated frame it came from, so results stay comparable across samples, locations, and conditions.
class
Defect count by type
Each detected feature assigned to a class using the agreed rule set, shown on the image.
Example, not a claimed result
In your report: Per-feature class, counts by class, and annotated overlays.

Confidence in every resultTraceable measurements, reviewed against your agreed reference method.
- Traceable scale
- The report records the image scale, calibration evidence, and a method-specific expanded measurement uncertainty. It does not use one product-wide accuracy number.
- Reference comparison
- The configured method is compared with your accepted reference method or reviewed annotations, and reports bias by measurement range and image condition.
- Detection performance
- Detections are evaluated against reviewed reference regions with precision, recall, and segmentation overlap, separated by the conditions that affect performance.
- Repeatability
- The locked protocol is rerun on the same inputs and on a defined repeat set. The review records variation from image acquisition, sampling, and analysis separately where possible.
What this result does not establish: Detects coating defects visible at the imaged surface and classifies them by type. Their electrical consequence depends on cell design and is confirmed by cell testing.
The measurement, today
Electrode coating is inspected by eye on a moving web. Pinholes and small agglomerates pass at line speed, and defect density is never quantified per unit area.
What it costs
A pinhole or agglomerate becomes a weak point that can drive a short or early capacity loss in the cell. Found on the web, the coating can be rejected; found in a finished cell, the whole cell is scrap.
From image to reviewed result
- 1
Image the web
Capture coated electrode under even illumination, on the line or a sampled strip.
- 2
Find the defects
Regions that depart from uniform coating are detected.
- 3
Classify by type
Each defect is labelled pinhole, agglomerate, streak, or uncoated patch.
- 4
Normalise per area
Counts become a defect density per square metre with a location log.
