Battery Anode Overhang Analysis

Ensuring an optimal anode overhang is key for the performance and lifespan of lithium batteries. Our Battery Anode Overhang Analysis allows you to measure the anode overhang in an easy and intuitive way. 

• Measure the anode overhang for each individual electrode with unparalleled accuracy.
• Visualize a color overlay or display numeric results in a table.
• Assess the anode overhang with respect to the right or left adjacent cathode.
• Measure the overhang along the anode contour or along a straight projection.
• Evaluate global measures, such as the distance from the highest cathode to the lowest anode.

Extreme bending of the anode sheets can cause delamination or cracks in the active material. The Battery Analysis Module offers effective tools to analyze anode shape.

• Visualize the shape of the anode as a spline curve.
• Locate the point of maximum curvature for each anode separately.
• Measure the exit angle for each anode.
• Visualize the level of local curvature as a color overlay.
• Set a tolerance for the curvature to detect sharp bends.

The Battery Anode Overhang Analysis integrates seamlessly with the powerful automation framework and reporting capabilities of VGSTUDIO MAX.

• Record your battery analysis as a macro and apply it to new data sets without any manual interaction.
• Create meaningful, concise reports for presenting and archiving the analysis results.
• The Battery Analysis Module is compatible with our fully automatic VGinLINE solution and the VGinLINE APPROVER..

• All analysis results can be assigned a tolerance to automatically make a pass/fail decision.
• Use the evaluation capabilities of VGSTUDIO MAX to combine tolerances of several analysis results into a global decision.
• Place visual annotations in the scene to highlight specific findings.
• Automatically create annotations based on conditions you define.

The Battery Anode Overhang Analysis relies on a user-provided segmentation of the anodes and cathodes. Try out our machine learning-based Paint & Segment tool or use your preferred method to create the segmentation. The Battery Anode Overhang Analysis offers a range of functions to detect segmentation failures either through visual inspection or by automated plausibility checks.

• Verify that the total number of electrodes matches the expected value.
• Perform other plausibility checks, such as whether most anodes are neighbored by two cathodes.
• Use "zig-zag" line visualization to verify the correct segmentation of the electrode tips at a single glance.
